Power Sources Covered in this review: CO2 - Spring Piston - Variable Pump -HPA (High Pressure Air)
Pro’s:
CO2 Airguns allow for fast repeat shooting, great for action shooters, generally CO2 Airguns will supply a medium power range. No need to pump or cock your CO2 powered weapon in-between shots and a CO2 power source can allow for a very realistic action of the gun you are shooting.
Spring Piston Airguns are best suited of single shot situations, they can provide low to high power output depending on the spring used. Spring Piston Airguns are very low cost to operate since you only need to buy the Pellets or BB’s. Spring Piston Airguns are not greatly effected by outside temperatures.
Variable Pump Airguns allow you to decide how much power your gun will have and can offer very high power output depending on the Airgun. Variable Pump Airguns are very low cost to operate since you only need to buy the Pellets or BB’s. Variable Pump Airguns are not greatly effected by outside temperatures. Variable Pump Airguns generally have very low recoil and vibration.
HPA (High Pressure Air) Airguns generally do not require pumping or cocking in-between shots and some even come in semi automatic or bolt action. HPA Airguns can have very high power output and even be used on larger game using large caliber ammunition. HPA Air Rifles have lower recoil and low vibration. HPA Airguns can be charged ahead off time so they are ready for use when you need them.
Con’s:
CO2 Airguns require the additional cost to buy the CO2 as they do not function without it. CO2 Airguns have a limited power output and lose power as you shoot and use up the CO2. CO2 Airguns are effected by hot and cold temperatures and will have less power in colder temperatures and may not even work in super cold environments.
Spring Piston Airguns require cocking before each shot. Spring Piston Airguns can have a lot of recoil and vibration, so much so that special optics must be considered when buying an optical sight. The action of the spring recoil can effect accuracy, especially if you are not use to the vibration and recoil or have spent some time practicing using a Spring Piston Airgun.
Variable Pump Airguns will require multiple pumps to achieved maximum power output which can take some time in-between shots. So you are going to have to work for each shot.
HPA (High Pressure Air) Airguns require the use of a manual pump to fill their built in air tank to maximum pressure and it does take a lot of time to manual fill an HPA tank. Alternatively you can have the air tank filled at a shop or buy a pressurization system similar to a scuba tank out paintball setup, the cost of this setup can be very high but will save you the castle of manually pumping air in to your HPA Airgun. HPA Airguns are generally a little more bulky then other Airgun systems since they have to accommodate fairly large air pressure tanks.
Well ANT (Advanced Novelty Tech) made an update model that supports a bunch more guns, that's a good thing of course. This new model is called the "FIRE" and it supports the following guns. I did find however that ANT list that the Gletcher NGT and Webley Mark VI Revolvers where supported by the FIRE but my findings indicated the CO2 screw on both these guns had a smaller diameter so they where not compatible. Other than that small discrepancy most of the other guns on their list should work just fine.
What exactly is the ANT Advanced Novelty Tech FIRE CO2 HPA Conversion Kit?
The Advanced Novelty Tech FIRE CO2/HPA Conversion Kit is a remote line adapter for Airsoft, BB, and pellet guns. Compatible with over 60 guns, it is easy to install and converts a compatible gun for use with a Paintball remote line and CO2 or HPA tank. Eliminating the need for disposable CO2 cartridges, while still being interchangeable with disposable CO2 cartridges, it delivers a longer, more powerful, and more consistent shooting experience between refills.
So what is the ANT Advanced Novelty Tech FIRE CO2 HPA Conversion Kit going to do for you?
Eliminate the need for the more expensive disposable 12 gram CO2 cartridges.
Use interchangeably with disposable 12 gram CO2 cartridges.
Use in conjunction with a Paintball remote line with standard quick disconnect fittings and a CO2 or HPA tank. (recommended use up to 1000 psi)
Shoot thousands of rounds before needing to refill your CO2.
Fits compatible Airsoft, BB, and pellet gun CO2 pistols.
Easy drop-in installation.
Overall cost savings.
More consistent FPS especially when shooting fast or in full auto.
Materials: Mostly plastic with some metal construction.
Weight: 1.3 pounds (586 grams).
Barrel: 5.5 inches, non-rifled.
Propulsion: 12 gram CO2.
Action: Revolver, single & double actions.
Ammunition Type: 4.5mm steel BB's.
Ammunition Capacity: 10 rounds.
FPS: 375.
Trigger Pull: The trigger pull on the Umarex Brodax CO2 BB Revolver is actually rather nice. If you decide to cock the hammer back and shoot it single action style then you get a little bit of that SAA Revolver like ratcheting sound. The trigger pull in single action mode is short with virtually no take-up and on the light side. Double action shooting with the Umarex Brodax CO2 BB Revolver is not overly long or heavy either so action shooting is totally possible with this BB shooting CO2 revolver.
Accuracy: I can not comment so far on the shooting performance for the Umarex Brodax CO2 BB Revolversince I have not shot it yet. The weather is getting nicer outside so that should happen pretty soon. The claimed FPS for the Umarex Brodax CO2 BB Revolver is stated at only 375 which I find seems a bit low for a none blowback fairly straight forward BB pistol with an almost 6 inch barrel so hopefully my testing shows performance up into the 400's which I am hoping for. The open sights are non adjustable but there are tons more options by taking advantage of the two rails top and bottom for adding either a red dot or laser to increased target shooting ability.
Build Quality: The Umarex Brodax CO2 BB Revolver is pretty much an all metal pistol with the outer shell being made up of plastic, there is a fair bit of internal metal going on along with the trigger, hammer and of course the inner barrel made out of metal parts. Mechanically the Umarex Brodax CO2 BB Revolver feels solid and even though it only weight in at 1.3 pounds it feels much heavier in the hand.
Realism: The Umarex Brodax CO2 BB Revolver as far as I know is not an exact replica of any real steal gun currently in production. It's basically a spin off of an ultra tactical .44 magnum revolver with a super beefed up front barrel assembly sporting all kinds of accessory option to be placed on the top and bottom rails. I like that Umarex made sure to recess the barrel opening so it has a more realistic barrel size. Like many new CO2 airguns coming out these days the CO2 is not only well hidden inside the grips but a handy Allen key is built into the handle.
Not the heaviest revolver on the market but it feels really nice in the hand and has good balance, the weight is not bad at all and feels heavier than 1.3 pounds.
Trigger action is really good in both single and double action, short light single action trigger and totally usable double action trigger.
CO2 is well hidden with built in Alan key in the handle.
Rails top and bottom for all kinds of accessory add on options.
Barrel is recessed for that larger caliber look.
Nice and discreet safety.
Comes with three 10 shot easy to load rotary magazines.
Low cost with high fun factor.
Cons:
Grips are a bit hard to remove to get at the CO2, may work-in over time?
All black sights are not great on dark backgrounds and are non adjustable.
Would have liked to see fps into the 400 range.
Comments:
The Umarex Brodax CO2 BB Revolver when I first picked it up did not appeal to me all that much, maybe knowing it was for the most part yet another mostly plastic BB revolver with those thin pop in disc magazines didn't help me take notice much. But as I have been playing around with the Umarex Brodax CO2 BB Revolver it has grown on me a lot. I think it has a really cool look that is also very usable in terms of putting juts about any accessory you want on this CO2 revolver. The hammer and trigger action are also both excellent for not juts an inexpensive Airgun but even a higher end airgun. And right out of the box, or should I say clam-shell plastic wrap, you get three rotary disc magazines which is a nice bonus.
My Vimeo Table Top Review for the Umarex Brodax CO2 BB Revolver:
I am showcasing here on the Replica Airguns website and over on the Replica Airguns YouTube channel a series of videos I am making for the purpose of selling some guns out of my personal collection. I simply have no more room for the new guns and in some cases I either have duplicate guns or very similar versions so there is no need to have both. Some guns I am less attached to and as I already stated I need to make room for some of the new stuff I will be reviewing and or buying for myself.
In this third Mike's Personal Guns For Sale video I am offering four BB rifles, three of which have full auto or at least burst mode ability and the fourth BB rifles is more of a Shotguns with the ability to shoot three BB's at once. Most of these BB rifles are really hard to get here in Canada now since one is not made anymore and the two are simply not currently being imported into Canada.
Make sure to watch my above YouTube video to see these four BB rifles I am selling and instructions on how you can take part in the sale and purchase of them. By the way I am only selling to Canadian residents since shipping cross borders is a little sketchy.
Here is a list of the BB Rifles I am selling from my personal gun collection:
When I say Airguns, I am referring to pretty much all BB, Airsoft, Pellet, Paintball and even Blank guns for most of the topics listed here.
Do’s:
Treat your Airgun just like you would a real gun. If something goes wrong, perhaps the outcome will not be as severe but do you really want to take a trip down to your local emergency ward to get a BB or Pellet removed?
Always assume your airgun is loaded, for some reason it always seems those empty guns are the ones that do the most damage.
Be discrete, If it looks like a gun other people will think it is a gun so don’t flash your airguns around in public. Keep it in a case when transporting and shoot it in an area that will not alarm other people.
Always wear eye protection when shooting your Airgun. Do you really want to shoot your eye out? No Joke!
Be aware of your surroundings like windows, hard objects that could make your ammo bounce back at you. Make sure you are shooting your Airgun in a safe direction at all times, know your target and beyond.
Use Airguns to teach others and learn how to safely and effectively shoot a gun. Airguns can be less intimidating then a real gun (Not so loud and very little recoil) and make for great start out and transitions guns.
Use Airguns to get more inexpensive trigger time and become a more experienced shooter. Airguns cosy only pennies per round to shoot and can be shot in way more areas than a real gun can, practice makes perfect so get shooting!
Use Airguns in areas where real guns may not be allowed or safe to use. Again, Airguns can be shot in all kinds of places, in your back yard or even in a properly setup indoor home range.
Use Airguns with adequate power for safe and humane pest control where real guns may be prohibited.Airguns are quiet and less likely for the bullet to travel long ranges which makes them ideal for close range pest control in areas where real guns are too loud and to powerful.
Don’ts:
Do not assume because it is an airgun it is not dangerous or simply a toy. Many Deaths have been caused by Airguns along with a lot of pain and suffering so treat your Airgun with respect. It is not a toy or you would find them in the toy department at your local store along with yo-yos and stuffed animals.
Do not point or shoot at people unless of course you are using an Airsoft gun in an Airsoft field or facility. Yes Airsoft guns are meant to shoot at each other (with appropriate attire like eye protection and full body clothing), but steel BB and Pellet can cause serious injury especially at close range and on direct skin contact.
Do not leave your Airgun loaded, you never know who is going to come across it and accidentally discharge it. Remember, a loaded gun is a dangerous gun in the wrong hands. You may know better than to assume the gun is undulated but children and even adults without any gun training will most definitely handle the airgun without consideration of the danger it poses.
Do not use an Airgun for self protection. See my related video. Simply put, Airguns are not practical for self defense because they rarely have enough Stopping Power. The ones that do have enough power need to be pre-charged and in most cases are only single shot meaning if you miss or don’t get the job done no the first shot then you are done.
Do not use an underpowered Airgun for pest control. See related video. Using a low powered BB pistol for pest control is cruel, you will only injure the animal making it suffer unnecessarily. Use a high powered pellet rifle to get the job done.
Do not take your gun apart, in most cases this will void the warranty and the reality is that airguns rarely need to be cleaned since no dirty gun powder is used. lead pellet rifles may require occasional barrel cleaning to keep the rifled barrel free of debris.
Do not over oil your Airgun, a little goes a long way and too much oil will just attracted dirt, use the right airgun oil and just enough to keep part functioning smoothly.
Do not over pump an Airgun. Over pumping an Airgun can cause damage to valves and seals and in a worse case situation a rupture the air pressure reservoir or even cause the airgun to explode!
With the popularity of the KWC - Cybergun 1911 Blowback CO2 Pistols and how super realistic they are in so many ways, it is no surprise that people often ask me if they can replace the original grips with grips made for a real 1911.
The short answer is yes you can! You will have to be prepared to remove just a little bit of material from the backside of both grips near the bottom of the handle where there is an area that has been flared out to accommodate the CO2. Not really a big deal, you can use a Dremel for the quick and easy approach or even some sand paper if you don't mind taking a little more time.
I don't often review target and or hunting rifles since for the most part Replica Airguns is all about well... replica airguns :) I have reviewed some of my own personal spring piston and pump rifles since I have them and there is a cross over in folks that like both the replica airguns and airguns meant for target and or hunting purposes.
We do have a small selection of spring piston rifles in our Replica Airguns Canada store suitable for target and small game so I thought I would point some of them out in this preview video.
First off let’s get one thing straight! What I’m looking for in a BB gun is more than likely going to be way different than what someone else is looking for in what they think is the “Best BB Gun” available.
Many people will determine the Best BB Gun as the BB gun that has the highest price tag, usually you get better quality the higher the price goes up but not always, there are times when perhaps you are paying for a name brand or cosmetic add ons that don’t always make the gun better or the best.
On the other hand, some people will determine the best BB gun as the one that is the least cost since they may not have a lot of money to spend, and an expensive BB gun is a BB gun that that person would not be able to afford or even own, far from an ideal or the Best BB Gun for them.
Many people only look at the specifications to determine if that particular BB gun is the outright best BB Gun. One specification that people seem to fixate on is how powerful is the BB gun in question? If it has the highest FPS then surely it must be the best BB Gun! That Pop can never saw it coming! What about cost of operation, so things like reliability and how many shots per CO2 you can get out of a BB gun. All important features to consider when picking out the Best BB Gun!
Style is another important part of what makes a BB Gun the Best option for you, are you wanting a classic BB Pistol? Perhaps a Modern BB Gun, Maybe even a BB gun that you can not get in your area because of gun laws? Style is a very individual preference and what looks good to me may look terrible to someone else.
One aspect that is very important to me, is realism, does the BB Gun operate the same and does it have similar metal and plastic parts as the real steel version? Does the BB gun I am considering have blowback operation and a true single or double action trigger like it’s big brother? What about a full size drop out magazine and the ability to field strip the BB Gun?
Some people want their BB gun for simple backyard good old fun shooting and so as long as it shoots pretty straight and works as it’s supposed to, then that is all they care about. Many real steel shooters want a BB Gun to operate exactly like their real steel version, so they can practice with it to get in more trigger time when going to a gun range is not an option.
Of course there are aspects like Reliability, Performance, Fit and Finish, Licensing and Build Quality that all determine what makes the Best BB Gun and again it really depends which of these qualities are most important to you that will determine which BB Gun is the best BB Gun.
So how do you determine which is the Best BB Gun? Make a list of what you are looking for in a BB Gun. Attributes like Cost, Performance, Build Quality, Style, Realism, Availability…
Once you have narrowed down your Best BB Gun list, get as much information on each BB Gun you are considering, to narrow the list down even more. There are tons of Youtube videos you can watch for your Best BB Gun final short list to help you determine your ultimate choice.
So please don’t ask me what the Best BB Gun is? I can not even tell you which one I like the best since my wish list changes from day to day…
First off we are not talking about 6mm Plastic Airsoft Guns but rather 4.5mm Steel BB versus .177 caliber Pellet.
Same but Different:
Generally speaking a BB CO2 Pistol and a Pellet CO2 Pistol are very similar, they just shoot a bit different types of ammo, that will determine a couple mechanical differences in both guns. You may come across a CO2 Pistol that can shoot both Pellets and BB's but these are not as common.
Magazine Types:
The fist main difference is usually the magazine design, since lead pellets don’t stack on top of each other very well compared to steel BB’s, action CO2 BB and Pellet pistols will have a very different types of magazine designs. Pellet CO2 Pistols will generally use a rotary type magazine while BB Pistols will use a stick or stacked ammo magazine. In terms of realism, a stick or stacked magazine is better suited than a rotary magazine. Some Action Pellet Pistols will have what looks like a stick magazine, but the stick will actually have two rotary magazine on either side. You will often find higher capacity magazines in BB CO2 Pistols since Rotary magazines usually only offer around 8 rounds (16 on a double sided stick style).
Another downside to a rotary magazine is knowing when you are out of ammo, a rotary magazine does not allow for this, it will just keep turning around and around no matter if there is ammo in it or not, so you need to listen to the the sound of the CO2 gun to determine when a rotary type magazine is empty. BB Action shooters do not have this problem since in most cases the magazine BB spring follower acts exactly the same as real steel gun follower locking back the slide on the last shot, stopping any follow up shots from happening.
Ammo Size:
Steel BB’s traditionally only come in 4.5mm which is the same as .177 caliber. Lead pellets can come in a myriad of sizes, the most comma being .177, .20 and .22 caliber but they can go as large as 50 caliber for PCP air rifles used to hunt even large game.
Barrel Rifling:
Another common difference between BB and Pellet CO2 Pistols is the rifling inside the barrels. Lead pellets need to spin in order for them to shoot straight. Steel BB’s on the other hand fly pretty true thought the air weather they spin or not. Rifling is most often not used in steel BB pistols because the hardened steel can damage the rifling and since there is little to no benefit in adding rifling to a BB guns barrel in terms of accuracy, then why even have it. Pellet pistols with their softer lead ammunition need to have the rifling in order to create the spin that keeps the pellet true and straight while in flight.
Accuracy:
Even though many BB CO2 Pistols can shoot accurately at close to medium ranges, they are not as accurate as a Pellet CO2 Pistol, especially as the distance become greater to your target. Not only does the spinning of the pellet help accuracy, but also the added mass of the lead pellet keeps them from being as effected by cross winds and airborne debris.
Hunting and/or Pest Control:
In most cases I do not recommend using a pistol for pest control because, plain and simple they are harder to shoot accurately. This is because there is no stock on a pistol to help steady the gun, and the front and rear sight are much closer together on a pistol than compared to rifle sights which means there is more margin for error when signing in a target. Pistols are generally lower powered than rifles which also plays a roll when considering a pistol for pest control since it may not have enough power to get the job done humanly. That said, there are pellet pistols deigned with power in mind, usually these are spring piston, or pressurized air powered air guns which can have a lot more power than a standard CO2 BB or Pellet Pistol.
Pistols versus Rifles:
This is not the forum for a full pistol versus rifle comparison. I can tell you that you will find a lot more pellet rifles than your will find BB rifles, they both exist but for the most part rifles are geared more towards target shooting and hunting. Most of the BB rifles available would be styled after replicas so the focus is not necessarily on power and or accuracy in these models.
Abundance:
In terms of Replica Action Shooters, BB Pistols outweigh the Pellet pistols by a land-slide. BB’s just work better in action pistols because the round hard steel ammo operates much easier and more reliably than the softer lead pellets, at least for action shooters. And the point of Replica Action Shooters is not so much power and accuracy but more so towards rapid fire good old back yard fun shooting.
Which is Best?
Well… Neither one is best, it just depends what you are looking for.
Do you want accuracy at longer ranges - if so maybe get a Pellet CO2 Pistol.
Do you want more realism in terms of magazine loading and your slide locking back on the last shot - then you may be in the market for a BB CO2 Pistol.
Do you want more power down range - heavy pellets are going to hit harder and truer than lighter Steel BB’s.
Do you want trouble free shooting - hard steel BB’s rarely miss-feed or misfire compared to softer Lead Pellets especially in action shooters.
The best is what’s best for you and not always what's best for me…
While the weather is still nice, I decided to setup some clay pigeon targets at varying further out ranges than the typically 30 feet I shoot on my deck. So I figured 40-60-80-100 foot ranges would be a good test to see if a 4.5mm Steel BB rifle could effectively hit targets at any of these ranges.
I did do a similar test earlier on using my Umarex Steel Force but I think the Steel Force may have been a bit underpowered for the 80-100 foot shots.
So today I brought out my Drozd Blackbird since it has a bit of power and what it may lack in accuracy it for sure makes up in volume! As with many of my shooting videos I captured all the fun using a bunch of different cameras and camera angles and today I even wore a dedicated lapel mic which I have a min-review for coming up shortly!
So make sure to watch my YouTube video and see how the Baikal Drozd Blackbird does shooting clay pigeons up to 100 feet away...
You guessed it, another Full Auto Fun YouTube Video! And another great Blowback BB gun from the past dusted off and brought out for some more shooting fun :)
With that said this video is me actually shooting my original Cybergun / KWC Licensed GSG 92 version that I modded to shoot full auto. It was giving me a bit of trouble today but it seemed to work out the kinks near the end.
In an upcoming Full Auto Fun Video I do plan to bring out a new KWC full auto ready M92 and Mini UZI to see how these factory full auto 4.5mm BB guns shoot out of the box.
I do have to say, modifying the PPK to Full Auto is not recommended, mine originally worked well but the heavy blowback in full auto eventually broke the firing pin setup and I lost it somewhere in my back field. I had to Macgyver a bolt in place to kind of work but now my Full Auto Modded PPK shoots out of control, what I mean by this is when I press the trigger, it does not stop shooting until all the BB's are gone. Safe, I don't think so!
My suggestion is to leave the Umarex Walther PPK as is, it truly is a an awesome CO2 Blowback BB replica with some really decent blowback recoil in a small airgun.
Full Auto Fun video number three this week and this one is perhaps the craziest one! When you take a Drozd Blackbird that already has a 800-1000 round BB magazine, convert it to 1200 rounds of full auto, add a custom JimC Barrel to it, some bulk CO2 and a bunch of other cosmetic accessories... Well you get the most ridiculous full auto BB gun you can ask for.
Since I had an extra 800-900 BB's more than I am used to when making these full auto videos, I decided to add a few additional targets over and above the clay pigeons I have been using so far. I picked up a nice fairly heavy gauge Santa tin and a rather solid hard wax candle from the dollar store that proved to add some drama to this Full Auto Fun video!
Make sure to also watch my first two Full Auto Fun videos:
If you like what you see in this video and want an absolutely crazy BB gun, then checkout our Replica Airguns Store where we Sell the Drozd BB gun and some add ons for it!
This "Full Auto Fun" video focuses on my KWC/Cybergun 4.5mm Steel BB CO2 Blowback Mini UZI BB Gun, where I kick of a short series based around shooting a bunch of 4.5mm Steel BB machine guns! Sounds like fun cause it is fun!
This KWC/Cybergun Blowback Mini UZI comes in a variety of versions, 4.5mm Steel BB and Airsoft versions, it also comes in RWS and KWC Distributed models.
In this video I basically shoot a bunch of clay pigeons positioned in various locations and film it using 4 different camera angles to spice things up a bit.
I also mention some upcoming videos where I will be shooting my RAP4 MP5 and Baikal Drozd Blackbird Full Auto BB guns so make sure to watch those video when I upload them later on this week!
In this "head to head to head" pistol shootout I compare three of my more powerful, or you could say effective air pistols against each other. Shooting at some pop cans from about 30 feet away to see how destructive each one is. I don't generally recommend air pistols for pest control simply because they tend to be less accurate and powerful than rifles, especially out at the longer ranges where a magnified scope is required and notably where the pesky vermin like to hang out.
I would have to say out of the three tested in this video comparison, the Webley Alecto in .22 caliber and the Modified Drozd Full Auto BB Gun would for sure get the job done at closer ranges. The Webley Alecto simply because it can hurl a heavy grain .22 caliber lead pellet right around the 500 fps mark which will take down small pests, again at close ranges.
My second choice or even first choice depending on how active the pest are would be my modified full auto 1200 rounds per minute Drozd that hurls 4.5mm Steel BB's at over 500 fps (under 4.2 foot pounds) at a rate of 20 BB's per second! A 4.5mm Steel BB traveling at 500 fps will penetrate fur and feathers very well and with most of the 20 BB's hitting a target in a matter of 1 second, that is going to humanly put a small to even medium sized pest down for sure. And yes the Drozd becomes a pistol when yuo take the rear stock off ;)
My last choice for the job is the Xisico XSP180 in .177 caliber since like the Webley Alecto it is only a single shot, so you got to make it count and being that it has less overall energy than the Webley Alecto again I would prefer the Alecto over the XSP180.
Watch my "head to head to head" Vimeo video to see how these three pellet pistols compare:
In this Comparison Video I go through the benefits and shortcomings of CO2, Spring Piston and Pump Airguns. I focus mainly on Airguns but there is a bit of a crossover with Airsoft guns.
All three systems (CO2, Spring, Pump) create pressure that forces the ammunition with a high force out of the barrel. Similar to how gun powder is the source of energy for a bullet.
Here are some basic statements that best describe CO2, Spring Piston and Pump Airguns.
CO2 Airguns:
CO2 Airguns use the expansion of CO2 gas to create the pressure required for the ammo.
CO2 Airguns generally store enough CO2 for multiple shots per cartridge.
CO2 Airguns have a limit as to how much power they can produce since CO2 has a set vapor pressure of 850 psi, or about 56 bar at room temperature which is around 25 C or 77 F. CO2 Gas also requires a warm environment to expand so warmer temperature and longer barrels help with power.
Some CO2 guns can also use pressurized air tanks in place of CO2.
Spring Piston Airguns:
Spring Airguns use the release of a pre-cocked spring and plunger system to compress air to power the ammo.
Spring Piston Airguns require the cocking of the spring between each shot so they are single shot only.
Spring Airguns are limited to how much effort is humanly possible to cock the spring into position. If you make the spring to strong then not everyone will be able to use the Airgun effectively. Too week of a spring and the Airgun will lack power.
Spring Piston Airguns are known for having a fair amount of recoil and vibration when the spring moves both forward and backwards quickly inside the Airgun.
Spring Airguns can use either a mechanical spring or a gas spring.
Pump Airguns:
Pump Airguns (either Single or Multi-Pump) store air pressure in a chamber that when released, powers the ammo.
Most Pump Airguns require at least 1 or more pumps, often up to 10 pumps for each shot and you generally only get one shot per set of pumps. Not to be confused with PCP Airguns (Pre Charged Pneumatic) which have large pressure tanks that are recharged with a high volume of pressurized air that is capable of shooting multiple shots per charge.
Pump Airguns are also somewhat limited to how much effort is humanly possible since the higher the chamber pressure, the harder it will be to pump the Airgun.
Misc Airguns:
Generally speaking both Spring and Multi-Pump Airguns have more potential power than a CO2 guns since CO2 has a set peek pressure limit.
Pump and CO2 Airguns are know to have very little recoil since the pressure is stored in a chamber and then released by a valve. No slapping back and forth of a large internal spring.
Pros:
CO2 Airguns:
CO2 Airguns allow for multiple shots per CO2 cartridge for more realistic action shooting.
CO2 Airguns do not require any human effort to charge the gun other than loading the CO2 and Ammo into the Airgun.
CO2 Airguns allow for true semi auto shooting ability.
Spring Piston Airguns:
Spring Airguns have the potential for high velocity since the larger and stiffer the spring, the greater the output force.
Spring Airguns do not require anything other than your ammunition, typically either a Pellet or BB.
Spring Airguns are mechanically very simple which makes them very reliable and less expensive to produce than other types of Airguns.
Pump Airguns:
Pump Airguns have the potential for high velocity since more pumps equals greater output force, only limited by the users strength and the pressure rating of the Airgun.
Pump Airguns do not require anything other than your ammunition, typically either a Pellet or BB.
Pump Airguns have next to no recoil which makes them very easy to shoot and highly accurate.
Cons:
CO2 Airguns:
CO2 Airguns require the purchase and use of CO2 or they simple do not work.
CO2 Airguns are very susceptible to temperature changes, especially cold temperature since CO2 needs a warm environment in order to expand. Cool down effect also plays a role in power output.
CO2 Airguns have a maximum set amount of power output.
Spring Piston Airguns:
Spring Airguns require the pre-cocking of the spring for each shot.
Spring Airguns can take some getting used to since the spring recoil/vibration requires a very lose grip (Military Grip) to shoot accurately with them.
Spring Airguns should not be stored pre-cocked since this can damage the spring, less so with gas spring versions.
Pump Airguns:
Pump Airguns require pre-pumping to pressurize the air chamber for each shot.
Pump Airguns, especially Multi-Pump Airguns take the most amount of human effort for each shot.
Pump Airguns need to stored with at least one pump in them or the seals can get damaged over time.
Another quick revisit of the KWC/Cybergun M92 Beretta - Taurus full metal, full blowback, CO2 4.5mm Steel BB pistol series. They come in several flavors but are all made by KWC and in many cases redistributed licensed by Cybergun. This Field Test Shooting Video Review focuses on the Cybergun Swiss Arms P92 version.
Now that I have a more standardized Field Test Shooting format, I though I would revisit this series of KWC/Cybergun Beretta - Taurus Replica BB Pistols and do a follow up Field Test to get some more camera angles and hopefully a nice tight target grouping using my standard semi rested position from 20 feet away.
I also incorporate some high speed video near the end of this Field Test Shooting video Review to go along with the Chronograph and target portion of the Filed Test Shooting review.
The KWC - Cybergun Full Blowback All metal serious of Replica CO2 BB Pistols has been hugely popular over here at Replica Airguns and for good reason, they are very realistic in looks and operation, are priced very respectably and replicate several of the more popular semi auto pistols.
FPS: 750 with Pellets and 800 with BB's for the US version (Up to 495 with Canada version).
Trigger Pull: The trigger pull on the Crosman MK-177 is medium length and fairly light. The trigger mainly releases the bolt so no pre-cocking of the trigger is required. The trigger is plastic but seems to work just fine as there is no real load on the trigger when shooting, you do need to get used to where the release point since there is some take up well before the trigger releases.
Accuracy: I found the Crosman MK-177 Air Rifle to be a very good shooter, getting about a 1 inch 10 shot grouping from 30 feet out in a semi rested position (sand bag up front, standing in the back). I also put 3 rounds through my somewhat failing Chrony Chronograph using 3,5 & 10 pumps and the MK-177 with the maximum 10 pump shot as high as 631 fps using 6.9 grain RWS lead pellets. I would expect the Canadian detuned version to shoot well below the 500 fps Canada limit much like my Canadian Crosman M4-177 I reviewed a while back.
Build Quality: The Crosman MK-177 Multi-pump Air Rifle is mostly molded plastic, but for a $100-ish Military Styled Replica Air Rifle it hits the mark in terms of affordability and if it was an all metal airgun you would more than likely expect to double or tripple this price point! Even though plastic is used throughout this Air Rifle, there are some internal metal parts where they need to be, the fit and finish seems to be good and I do not get the feeling the Crosman MK-177 is cheaply made in any way. The fact that most parts are molded means there is very little that can snap or break off and will make this air rifle even more durable longterm.
Realism: The Crosman MK-177 is a lose replica or copy of an FN SCAR Assault Rifle or ACR. It is not exact in terms of true dimensions to accommodate the pumping mechanism, You will not find very many working parts as just about everything is molded into the plastic on this Crosman MK-177 rifle. Unlike the Crosman M4-177 the lower magazine area is not removable and the rear stock is also none adjustable, I am not sure why Crosman didn't add these features to the MK-177 like they did to the M4-177? I am glad to see another Replica Assault rifle on the market as so few of them are available in Pellet or steel BB shooters.
None red dot version comes with detachable and adjustable iron sights.
Rails on top and sides for accessories.
Option of shooting pellets or BB's, I would stick to pellets and save the barrel since it is not semi auto.
Feels super solid since there are very few moving parts that could break.
Looks like the Crosman M4-177 Pellet magazines are compatible.
Cons:
Mostly plastic and just about everything is molded into the gun.
Bolt and magazine are on opposite sides?
Would of been cool if Crosman made a dedicated BB magazine?
Comments:
The Crosman MK-177 Multi-Pump Pellet/BB Air Rifle is very much like it's brother the Crosman M4-177 with a few plusses and a few minuses when comparing the two of them together. On the plus side the MK-177 has a bit more power and also the pumping is much easier while yielding higher internal pressures. On the downside the Crosman MK-177 is almost entirely molded plastic with no removable lower magazine or adjustable stock, and the bolt has been switched around to what I feel is the wrong side since now you need to index the magazine on one side and work the bolt on the other requiring a less efficient approach. Either way it is nice to have another replica air rifle on the marker and for the relatively low price you get a nice accurate pellet rifle, great for target shooting and even small pest control.
Watch my Vimeo Full Video Review of the Crosman MK-177 Pellet/BB Air Rifle:
I wanted to cover some basic Airgun, Airsoft Gun, Blank Gun and Paintball Gun information on what do they all shoot, what makes them shoot and some other miscellaneous info thrown in along the way...
Your should also watch the video attached at the bottom of this post as it goes into a fair amount of detail.
Let's begin with the types of ammo used:
Airgun Ammo
Airgun ammo for the most part is broken down into BBs and Pellets, the most standard size BB and Pellet is the 4.5mm or .177 caliber Steel BB and Lead Pellet. You can also get Pellets in other calibers and even other materials other than lead such as steel or aluminum, some can have plastic skirting around a metal interior.
Pellets also come in a variety of caliber's like .177, .20. 22. 25 and even larger but then I would start considering them to be bullets as they will take on the shape of a bullet when they get into the larger sizes.
Airgun Ammo is not be fired at people, it is primarily used for target and hunting small game.
Airguns can use Spring Pistons, CO2, Compressed Air and Multi-pump propulsion systems.
Airsoft Gun Ammo
Airsoft Guns for the most part shoot round 6mm (.22 caliber) plastic BBs which come in a variety of weights ranging from .12 grams up to .48 grams. There are larger Airsoft BBs such as 8mm and even larger.
There are biodegradable and even tracer florescent Airsoft BBs available.
Airsoft Ammo is traditionally used for Airsoft battles and can be fired at people using protective gear. Airsoft Ammo can also be used for target shooting.
Airsoft Guns can use Spring Pistons, Spring Piston - AEG (Electric Motor) CO2, Gas (Green, Red, Propane) and Compressed Air propulsion systems.
Paintball Gun Ammo
Paintball Guns or "Markers" have been historically used for the sport of Paintball but their whereabouts came from the need of ranchers and forestry workers to mark trees. Hence the name "Marker"
Paintball ammo comes in a variety of sizes ranging with the most common being .43 and .68 caliber. They are generally made from a gelatin outer coating containing primarily polyethylene glycol, other non-toxic and water-soluble substances, and dye, they are usually biodegradable.
Paintball Guns can also shoot a variety of Paintball Ammo that can be made out of Rubber, Plastic, Glass and they can also contain Powders and even Pepper for use in non lethal defense.
Paintball Guns can generally use either CO2 or Compressed Air as their propellant.
Blank Gun Ammo
Blank Guns are just like Real Guns but without the dangerous bullet at the end of the brass shell. Other than that they work exactly the same as a Real Gun!
Blank Guns are used when a bullet is not required or even wanted. For instance... Gun safety, gun training, training animals to be around guns and/or loud noises, Props for Movies - Stage - Film - TV, Collectors that do not want the red tape associated with owning a Real Gun or when owning a Real Gun is prohibited.
Blank Guns can shoot a variety of sized ammo, most common are .22 caliber crimped, .380 crimped, 8mm P.A.K. and 9mm P.A.K.
Blank Guns use gun powder as their means of operation.
Here are the most common forms of propulsion used in the guns we discussed earlier:
CO2
CO2 is the most common propellant in Airguns (BB and Pellet), it is also used in Airsoft Guns and Paintball Guns.
CO2 is a compressed gas which expands when released, it requires a warm environment to fully expand and tends to cool it's surroundings quickly when shot fast or in full automatic which can slow the velocity of the projectile and even freeze up the gun being used.
The most common reusable CO2 cartridges are 12 and 88 gram but you can get larger CO2 tanks in a variety of sizes that can be refilled with CO2.
Gas
Gas is used primarily in Airsoft Guns, I have not personally seen an Airgun that is made to use Gas other than CO2.
Gas is similar to CO2 in that it is a compressed gas that expands when releases, it also cools down the gun it is being used in and requires a warm environment.
Gas comes in a variety of names, Green Gas, Red Gas and Propane Gas. Green Gas contains Propane as it's base but has additives in it like silicone for lubrication .
Red Gas is know to be a bit more powerful than Green Gas as it has Chlorodifluoromethane or HCFC-22, R22 or Freon 22 used in refrigeration which turns to a liquid under a slightly higher pressure giving you slightly higher fps.
Many people use propane gas with an adapter that allows the mixture of silicone as propane is cheaper to buy.
Compressed Air (HPA)
Compressed Air (HPA - High Pressure Air) is most commonly used in Airguns and Paintball Guns but some people use it for their Gas based Airsoft guns.
The compressed air comes from high PSI tanks that can be purchased in a variety of sizes and contains compressed air at pressures up to 5000psi.
These tanks are reusable and usually need to be refilled at a paintball or scuba shop, some people buy their own compressors or large scuba tanks for refilling purposes.
Some Compressed Air (HPA) guns have their own built in tanks that can be filled with a compressor or even a manual pump.
Compressed air does not cool down the gun it is being used in and is a great option for high output or fully automatic guns.
Multi-Pump Pneumatic
Multi-Pump Pneumatic systems are most commonly used in Pellet and/or BB guns.
Multi-Pump Pneumatic guns use the same principle as HPA - High Pressure Air guns in that they require pressurized air as the propellant. The main difference with Multi-Pump Pneumatic guns, is that you do all the work by pumping the gun between shots. Generally speaking you pump the gun 3-10 times, take a shot and repeat this process.
Multi-Pump Pneumatic guns are not effected by air temperature and are great for target and small pest control.
Spring Piston
Spring pistons are generally found in Pellet Rifles and Pistols but some Airsoft Guns also use a Spring Piston System and generally speaking Spring Piston Guns are single shot only or in other words, the Spring needs to be drawn back before each shot. Spring Piston Guns can have magazines that allow for quicker repeat shots.
Spring Piston Guns come in many cocking configurations, Brake Barrel and Side lever to name a couple.
The Spring can be a Mechanical Spring or a Gas Spring.
Spring Piston Guns are not effected by temperature and are often used for small game hunting and target shooting.
Automatic Electric Guns (AEG)
Automatic Electric Guns are generally found in Airsoft Rifles but there are some Airsoft Pistols (AEP) that use this same system.
Automatic Electric Guns use a similar system to a Spring Piston gun but have an electric motor that does all the work of drawing back the spring. You can even have fully automatic AEG guns.
The power for the electric motor comes from removable batteries, so it is a combination a battery supplying the motor with the power to draw back the spring that creates a pillow of air that shoots the BB.
AEG Airsoft Guns are great for situations when you require high capacity magazines with full auto capability.
Gun Powder
Gun powder is used in Blank Guns, in the same manor that it is used in a Real Gun, the charge from the Gun Powder supplies the force required to operate the blowback in most semi auto Blank Pistols, it also creates the sound of a live round along with the muzzle flash which makes Blank Guns great for training and as Props for Movies and Film.
Because the kinetic energy from a blank gun is the same as a real gun, blank guns can be very dangerous when used in close proximity to an object, see my "Are Blank Guns Dangerous Video"!
Some other Gun Relevant Terminology:
Blowback
Blowback operation is when some of the force of the propellant is used to move the slide backwards, which in most cases cocks the hammer for single action and can also pickup and chamber a round into the barrel.
The slide spring supplies the energy for the return to the forward position of the slide.
Blowback Guns do rob some power from the bullet force and in the case of CO2 or Gas Guns the also reduce the amount of shots per CO2 or Gas fill.
Revolver, Semi Automatic
Revolver: Revolvers feed ammunition via the rotation of a cartridge-filled cylinder, in which each cartridge is contained in its own ignition chamber, and is sequentially brought into alignment with the weapon's barrel by a mechanism linked to the weapon's trigger (double-action) or its hammer (single-action)
Semi Automatic: semi-automatic pistols use the energy of one shot to reload the chamber for the next. Typically recoil energy from a fired round is mechanically harnessed. After a round is fired, the pistol will cycle, ejecting the spent casing and chambering a new round from the magazine, allowing another shot to take place immediately.
Single Shot, Repeater, Semi Automatic & Fully Automatic
Single Shot: A Single Shot Gun needs to be reloaded each time it is shot.
Repeater: Repeating action Guns are single barreled guns containing multiple rounds of ammunition. These rounds are loaded from a magazine by means of a manual or automatic mechanism, and the action that reloads the rifle also typically re-cocks the firing action. The term repeating rifle is most often applied to weapons in which the next cartridge is loaded by a manual action, as opposed to semi-automatic rifles, in which the force of one shot is used to load the next.
Semi Automatic: A semi-automatic, or self-loading, firearm is a weapon that performs all steps necessary to prepare the weapon to fire again after firing.
Fully Automatic: A Gun that uses either its recoil or a portion of the gas propelling the projectile to remove the spent cartridge (in the case of a gun-shell), fire again repeatedly, as long as the trigger is held down or until the magazine is exhausted. Automatic Guns are distinguished from semi-automatic Guns in their ability to fire more than one shot in succession once the trigger is pulled.
Single-Action (SA): trigger performs the single action of releasing the hammer or striker to discharge the firearm each time the trigger is pulled.
Double-Action (DA): The trigger both cocks and releases the hammer or striker
SA-DA: A SA/DA firearm combines the features of both mechanisms. You can pull the trigger in Double Action when the hammer is down which cocks and releases the trigger or you can cock the hammer with your thumb and then release the trigger using Single Action to fire the weapon.
Lever Action, Pump Action, Bolt Action
Lever Action: In a classic lever-action firearm, rounds are individually loaded into a tubular magazine parallel to and below the barrel. A short bolt is held in place with an over center toggle action. Once closed, the over center action prevents opening solely by the force on the bolt when the weapon is fired. This toggle action is operated by a hand grip that forms part of the trigger guard. When operated, a spring in the tubular magazine pushes a fresh round into position. Returning the operating lever to the home position chambers the round and closes the breach.
Pump Action: With a pump-action firearm, the action is operated by a movable fore-end that goes backwards and forwards to eject, extract, and chamber a round of ammunition. Pump-actions are usually associated with shotguns.
Bolt Action: The bolt opens and closes the breech end of the barrel and contains the firing pin. The bolt is held in place with a lever that fits into a notch. Moving this lever out of the notch will release the restraint on the bolt, allowing it to be drawn back. An extractor removes the spent cartridge, which is then ejected through the lever slot. A spring at the bottom of the magazine pushes up the reserve rounds, positioning the topmost between the bolt and the chamber at the base of the barrel. Pushing the bolt lever forward chambers this round and pushing the lever into the notch locks the bolt and enables the trigger mechanism.
Magazine vs Clip
Magazine: A magazine is an ammunition storage and feeding device within or attached to a repeating firearm. Magazines can be removable (detachable) or integral to the firearm. The magazine functions by moving the cartridges stored in the magazine into a position where they may be loaded into the chamber by the action of the firearm. The detachable magazine is often referred to as a clip, although this is technically inaccurate.
Clip: A clip is a device that is used to store multiple rounds of ammunition together as a unit, ready for insertion into the magazine or cylinder of a firearm. This speeds up the process of loading and reloading the firearm as several rounds can be loaded at once, rather than one round being loaded at a time. The term "clip" is also frequently used to refer to a detachable magazine, though such usage is incorrect.
Action: Semi auto, double action only with blowback.
Ammunition Type: 6mm plastic Airsoft BB's.
Ammunition Capacity: 15 round stick magazine.
FPS: 380.
Trigger Pull: The Double Action Only trigger pull on the Umarex Walther P99 CO2 Blowback Airsoft Pistol is long but not overly heavy for a double action trigger, it does have a break point mid way where it locks partway back, I presume this is the point in which a BB is loaded from the magazine into the barrel? The rest of the pull is still medium but much shorter with a distinct release point.
Accuracy: I did do a quick preliminary test before I made this table top review to get an idea of where this gun performs in terms of FPS and accuracy, I shot 5 rounds through my Chronograph on a fresh CO2 and got an average of 333FPS which was a bit lower than the claimed 380 but it was not the hottest of days. I also stepped back 20 feet and from a semi rested position I was able to get 9 shots within 2 inches of each other which was not bad for a DAO gun that I have never shot before. I did shoot a bit down and to the left with the set sights.
Build Quality: The Umarex Walther P99 is well built for its rather low price tag, it may not have all the bells and whistles but it does get the job done with good fit and finish and materials used. You will find a plastic/polymer frame but there is a lot of metal where it would normally be found on the real steel version like in the slide, magazine, trigger, slide catch, magazine release, inner barrel and many other internal parts. No real complaints here!
Realism: The Umarex Walther P99 CO2 Blowback Airsoft Pistol is pretty close in looks to a real steel Walther P99 with the exception of a missing decocker, but I'm pretty sure this is the same with the real steel DAO version? There is also the funny looking safety on the right side of the frame found on many Umarex airguns. I have to mention the red tip but again this can be removed and even when removed the barrel it is still recessed which adds to the realism. The Blowback action, Walther licensing and nice heavy weight all add up to make this Airsoft pistol look and feel the part.
Metal slide and internal parts gives it decent weight.
Rail for accessories.
Well hidden CO2 screw.
Walther licensing.
Recessed inner barrel.
White dot sights, easy to use.
Right amount of power for indoor CQB style airsoft games.
Cons:
Comes with a red tip even in Canada.
Double action only, so trigger is a bit heavier.
Kind of funny safety, not like the real gun.
Blowback was a bit sluggish.
Comments:
Overall the Umarex Walther P99 CO2 Blowback Airsoft Pistol is a very good buy, it's a decent replica of the real steel Walther P99 with blowback operation, lots of metal parts, good fit and finish, decent performance and full Walther licensing and trademarks. All at a very affordable price tag. It may lack some of the extras you will find on more expensive and more functional Airsoft pistols but the simplicity of the Umarex Walther P99 CO2 Blowback Airsoft Pistol means it will most likely be a bit more reliable with less to go wrong down the road. If you have been looking for a nice Walther styled replica in an Airsoft version this may be just be the ticket!
