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.
In this Comparison video I go through the benefits and shortcomings of both Blowback and Non-Blowback Airguns. I focus mainly on Airguns but there is a definite crossover with Airsoft guns.
Here are some basic statements that best describe both Blowback and Non-Blowback Airguns.
Blowback Airguns:
Blowback Airguns usually have a movable slide that moves back and forth with each shot.
Sometimes the blowback operation is internal (Internal bolt) so there may not be an external moveable slide.
Some CO2 is used to move the slide rearwards in a Blowback Airgun.
The Blowback motion of the slide with some blowback airguns can also cock the hammer or internal striker allowing for true single action trigger pull. But not always!
Some Blowback airguns have the potential for full auto capabilities since they can have a true semi auto action.
There is some noticeable recoil from the Blowback action simulating the recoil of a real gun.
Non-Blowback Airguns:
Non-Blowback Airguns can have fixed or movable slides but they will not cycle back and forth with each shot.
Non-Blowback Airguns tend to have less working parts since no Blowback valves are required or even a moveable slide.
There are some Blowback and Non-Blowback Airguns that field strip similarly to their real steel counterparts but this is most commonly found in Blowback Airguns.
Non-Blowback Airguns require the shooter to cock the hammer for single action shooting or use a double action trigger pull for semi auto like performance.
Pros:
Blowback Airguns:
Blowback Action causes a noticeable recoil which makes the airgun feel more realistic.
Blowback Airguns in some cases have true semi auto action with true single action triggers which mimic the authenticity of the real steel versions of the guns they replicate much better making them better training tools.
Having some recoil makes blowback Airguns potentially better training tools.
Blowback Airguns look really cool when shooting them and are great action prop guns.
Non-Blowback Airguns:
Non-Blowback Airguns tend to have less working parts so less to go wrong and more reliability.
Non-Blowback Airguns can be more accurate since the recoil from the blowback is not a factor.
Non-Blowback Airguns have more potential power and more shots per CO2 since no CO2 is robbed for the blowback operation.
Cons:
Blowback Airguns:
Blowback operation can rob some of the power and will also rob how many shots you get from the Airgun.
Blowback Airguns are effected even more by cold weather and the cool down effect.
The recoil from Blowback Airguns can effect accuracy for some shooters.
Non-Blowback Airguns:
Non-Blowback airguns are generally double action when shooting semi auto and so the trigger pull will be longer and heavier.
Non-Blowback Airguns do not replicate the recoil action of a real gun.
Non-Blowback Airguns do not look as cool to shoot and are not as good of an action prop gun.
I finally answer the question... Which Airgun is the Best? There has to be a best airgun out there right? So let's cut to the chase and stop waisting everyones time and money buying the third Best Airgun or even the second best Airgun! Why would you even want anything other than the very best Airgun available to mankind!
I really hope you weren't one of the gullible ones that actually bought something other than the Best Airgun, well I guess you're going to have to watch my YouTube video to find out which Airgun is the Best Airgun of all time...
I stopped by the ICS Booth, we don't sell too much of their products but have carried a few items from time to time. ICS caries some nice quality Airsoft guns including the M1 Grand with real wood stock, and some AK & AR variants.
One of our suppliers had the new FN Herstal Five-seveN Blowback Airsoft pistol, I believe made by Marushin. Like the real FN Herstal Five-seveN, the pistol is pretty much all polymer including the slide and frame. This pistol also uses CO2 in the full size drop out magazine which should make it fairly powerful.
Looks like there is another Dan Wesson contender available now in the form of a Swiss Arms S&W 357 Magnum 4 inch and 6 inch barreled version, they look really nice and like the Dan Wesson have the realistic reusable brass shells that hold the 4.5mm Steel BB's.
Ever considered owning a mobile Gunsmith vehicle, look no further, I came across this pimped out Firearms Van complete with machine guns mounted in the front :) Inside was a complete firearms workshop.
Last but not least, we had some fun while in Vegas. I go down for the SHOT Show for business but I also bring my wife and we make time for some non business related activities. I generally stay at the WorldMark resort each time and this year the weather was pretty nice so we where able to get some sun by the pool a couple of days and I even got a tan line! Of course the food and entertainment is always awesome in Vegas.
We carry a lot of the G&G line and perhaps have as much in stock as you would find at the G& G booth ;) I did see a few items we do not have in stock so I will have to see what I can do about that. Some products that I hope to see added to our Canada Replica Airguns Store would for sure be the M1 Grand and our Canadian Military Colt C7A1/2.
One company I took notice of was Inokatsu, they make super high quality Airsoft guns. I was drawn to their Sig Sauer P229 and 1911 pistols that by the way are made out of real steel and as close to the real version as possible without it being a real gun. The Inokatsu pistols I looked at are not cheap and will set you back over a grand but are as close as you can get to a real sidearm as possible in an Airsoft version. They feel amazing to shoot with heavy blowback and that sound real steel makes when the slide snaps back.
Let me know if you're like me and would be willing to part with a substantial amount of money for one of these treasures?
So it's 2014 but I still needed to make my 2013 Airgun, Airsoft Gun and Blank Gun Collection Favorites for 2013. It's become a tradition I guess you could say. No I do not show all the guns in my collection but I do cover most of my favorites and also some new guns I picked up in 2013.
Here's a peek but make sure to watch the YouTube video bellow where I go over all my top picks for 2013. You can also buy many of the guns I show in this YouTube video over in our Canada and US Replica Airguns Store!
Trigger Pull: The trigger pull on the KSC M11A1 GBB Airsoft Machine Pistol is pretty much exactly what you would expect from this fast firing single action only semi and full auto machine pistol, it has a really short take-up and then a nice crisp light trigger pull. Since it is an open bolt system, you will need to pull back the bolt for the first shot, releasing the trigger releases the bolt, just like with a real M11A1.
Accuracy: At this point because I received this gun from another collector in used condition, it is not working 100%, the hop-up bucking was damaged and the new ones I ordered are not the correct versions for this Airsoft gun. It does shoot but it is temperamental, sometimes the bolt will not cycle all the way and I have no idea how this is effecting the fps and accuracy. It would not be fair to test it in this condition, hopefully I can find the right hop-up bucking for it and do the Field Test Shooting Review at some point.
Build Quality: MyKSC M11A1 GBB Airsoft Machine Pistol has been used a fair bit so it is somewhat battle scarred, still it looks pretty good and other than the Hop-up bucking problem I am having it should be in working condition, unfortunately without the correct hop-up bucking, this gun will not work properly. Hopefully I can find a hop-up bucking? Even though much of this machine pistol is plastic externally, it has held up very well, the metal parts do also help to balance it off and give it a decent overall 3 pound weight which feels good considering it is such a small gun.
Realism: The KSC M11A1 GBB Airsoft Machine Pistol is a very close copy of the real steel Cobra M11A1 Machine Pistol, all the parts appear to function just like the original Cobra RPB Industries M11A1 and it even field strips in the same manor. The full licensing and trademarks also help to make this replica very believable.
Very realistic and accurate replica with full Cobra RPB Industries licensing.
Even though there is lots of external polymer, it still has good weight to it.
Full metal 40 round drop out magazine, holds BB's and Gas.
Everything works like the original, field strips and lots of mechanical parts.
Shoots in both semi and full auto.
Cons:
Hard to get here in Canada and hard to get parts here in Canada.
Mostly plastic main build - Limited usage of metal and steel.
Have no idea how it will perform because it is not functioning at 100%.
Comments:
Well I've pretty much said everything I can say without actually shooting it? Even though my used KSC M11A1 GBB Airsoft Machine Pistol is not in 100% working condition, I still like having it as I like the replica aspects of owning it, how else would I get my hands on a .380 caliber full auto machine pistol here in Canada ;) And you never know, I may just luck out and find the proper hop-up bucking for it and then have the chance to do my Field Test Shooting Review for you all :)
My Vimeo Table Top Review of the KSC M11A1 GBB Airsoft Machine Pistol:
Trigger Pull: The trigger pull on the G&G AR styled Airsoft CM16 Raider is very smooth, the CM16 Raider uses a mechanical trigger that once the charging handle has been pulled back or "charged", works in a single action only manor with a slight bit of take-up and then a light predictable release. Each time the closed bolt gas blowback system shoots a round in semi or full auto, the internal action is ready for the next single action shot.
Accuracy: So far I have not tested Version 2 of the G&G CM16 Raider, but I have tested Version 1 so here are the result I got with Version 1 until I do my official Field Shooting Test with Version 2. When shooting from a 30 foot distance I did get some nice closely grouped shots from the G&G CM16 Raider Gas Blowback but when shooting in full auto it did spread apart somewhat, maybe from the GBB recoil? Version1 of the G&G CM16 Raider GBB shot an average of just over the 325 fps, I was using .25 gram BB's and it was a cool day so you can expect higher fps out of the G&G CM16 Raider when conditions are better.
Build Quality: The G&G CM16 Raider GBB being built on G&G Combat Machine Platform is targeted more for the price conscience person. The quality is consistent and good and I did not mind having more plastic in the G&G CM16 Raider GBB as my plan from the beginning was to add a lot of extra accessories and starting out with a somewhat lighter footprint made the gun still relatively usable even when all geared up with extra accessories. I also feel the plastic or polymer fiber upper and lower receiver and RIS rail system will also wear better than steel as it is more likely to flex rather than break in many situations, not to mention metal will show scratches and wear more over time.
Realism: Airsoft AR rifles in my opinion are very realistic in general, even the AEG versions work just like the real steel AR's with working charging handles, dust covers, bolts, magazine, adjustable stocks and sights, but I would have to give the advantage to the gas Blowback systems like the G&G CM16 Raider GBB as it has a full internal bolt with some decent recoil, it can also be field striped very similarly to a real AR15 rifle. The shot count is more like what you would find in an M16 or AR rifle which means you will need to consider ammo shot assuage and reloading more carefully when using it in an Airsoft game.
Super affordable Gas Blowback Airsoft AR M16 styled Rifle.
Very high rate of fire in full auto.
Polymer shell is both light and very durable, does not show scratches or wear as easily as metal.
All most every part is operational - Fully Ambidextrous now.
Can be fully customized, lots of mounting points on the RIS Rail system.
Fully adjustable Crane Stock.
Removable rear Iron Sight can be swapped out for other sighting systems and hardware.
Version 2 is a significant upgrade from Version 1.
Internals can be swapped over to make it an AEG gun.
Cons:
Some people may not like the polymer RIS rails and upper and lower receiver?
Would have liked to have seen some sort of a plate over the pistol grip to finish it off.
Comments:
I already really liked Version 1 of the G&G CM16 Raider GBB Airsoft AR Rifle and even bought a bunch of magazines and gear to sport mine up for use in some local Airsoft games, the upgrades and improvements found in Version 2 are the icing on the cake! I am hoping the internal performance enhancements will increase the FPS just a bit and Gas efficiency somewhat over Version 2 but will find out when I give it a thorough testing shortly. If you have been a bit scared off by the higher prices of some GBB Gas Blowback Airsoft rifles then perhaps take a look at the G&G Combat Machine Platform CM16 Raider in GBB, it may just change your mind about Gas Blowback Airsoft rifles!
My Vimeo Video Review for the G&G CM16 Raider Airsoft GBB AR Styled Airsoft Rifles:
Every so often I come across some interesting guns that people are willing to trade or sell me, if the price is right or the trade involves a gun I can part with, then I go for it and hopefully end up with something I may not be able to get new or that for me is hard to acquire in Canada.
My most recent trade added two new guns to the collection, a KSC M11A1 Airsoft Machine Pistol and a Daisy Power Line 2003 .177 Caliber Pellet Pistol.
Both of these guns are very hard to get since the KWC Airsoft M11A1 shoots a bit too week for import into Canada, and the Daisy 2003 is no longer in production.
The KSC M11A1 is a 6mm Airsoft pistol that shoots in both semi and full auto using a Gas Blowback open bolt system, it is a replica of the .380 Caliber Cobra RPB Industries M11-A1. Mine came with a mock suppressor and 7 magazines, although not all of them are in working condition. The KSC M11A1 is in working condition but needs a new Hop-up Rubber Bucking which I have on order.
The Daisy Power Line 2003 seems to be in really good condition but still needs to be tested, it is one of the only true blowback semi auto pellet pistols I know of, what I mean by this, is it has a true blowback system with a true single action trigger which means it can be converted to full auto which is one of the reason Daisy may have discontinued it. The Daisy Power Line 2003 uses a very interesting 35 round rotational magazine. Some say it is loosely styled after a Browning High Power pistol.
Stay posted for reviews on both of these pistols down the road.
You may wonder why I am doing another video on the G&G CM16 Raider Gas Blowback Airsoft AR Rifle? That's because the one I have here in this Update Video is Version 2 and yes there is a difference. So far I can only tell you about the obvious stuff since I really have not tested it out to see if there are any other performance gains with Version 2 over Version 1.
G&G has made some improvement with Version 2 enhancing several areas:
First off, there is now a selector switch on both sides of the receiver allowing for left or right handed use.
Carrying on with the ambidextrous theme, G&G also added a magazine release to the left side of the receiver.
Another missing feature was a bolt lock out when your magazine was empty, this has been added and so the bolt will lock back about 1/3 the way back locking out the gun and letting you know when you are out of ammo.
The bolt release on Version 1 was just for show and did not function. On Version 2, with the bolt lock, G&G also added a working bolt release.
Those are some pretty significant improvements to the G&G Armament CM16 Raider GBB Version 2 in my books! So now it's time to test it out and see if full auto mode has been improved. I found with Version 1, that when using full auto, the G&G CM16 Raider GBB would have some trouble getting through a full mag dump but when shooting very quickly in semi auto had no problems at all.
We just received an order of KWC products so if you've been waiting for some out of stock items then go take a look! By the way, the KWC Beretta / Taurus full metal blowback BB and Airsoft versions now come semi and full auto enabled!
I originally made this Field Test Review Video a few months ago but had to pull it down because it featured two WE Products. The WE AK74-UN and the WE G18C which unfortunately looks a bit like a Glock. If you are not familiar with the video I made on the Glock Trademark Infringement Cease Order I received then you should probably watch that video, it will fill in some of the gaps on why I had to cut out the WE G18C portions from this video and repost it with only the parts that showcase the WE AK74-UN.
Anyways you can still read my Original Field Test Review post minus the video and photos of the WE G18C.
Action: Semi & full auto, single action only with full blowback.
Ammunition Type: 6mm plastic Airsoft BB's.
Ammunition Capacity: 16 round full size drop out metal magazine.
FPS: 280+.
Trigger Pull: The Single Action Only trigger pull on the Cybergun - VFC Smith & Wesson M&P 9C GBB Airsoft Pistol is kind of what I would expect form the real Smith & Wesson M&P 9C, fairly light with a small amount of take-up and creep but still fairly short. And the trigger safety actually works just the same as the real steel Smith & Wesson M&P 9C!
Accuracy: I have already done my dedicated Field Test Shooting Video for the Cybergun - VFC Smith & Wesson M&P 9C GBB Airsoft Pistol so check out the link here, This very short barreled pistol is not going to win any target shooting contests but it faired well and even shot a bit tighter groupings and higher fps than I expected. Most importantly it worked exactly as it was supposed to without any problems.
Build Quality: The Cybergun - VFC Smith & Wesson M&P 9C GBB Airsoft Pistol is extremely well built and you will find metal and polymer in pretty much the same places as you would find on a real S&W M&P 9C. Fit and finish and quality of materials seems really good, I am really happy with the work VFC is doing with their guns, at least from what I see here with their Smith & Wesson M&P 9C GBB Airsoft Pistol.
Realism: The Cybergun - VFC Smith & Wesson M&P 9C GBB Airsoft Pistol is based on the real steel version Smith & Wesson M&P 9C and I have to say this is one of the most bang on replications of any gun I have seen, you would have to get right up close to tell the difference and only then if you looked at either the magazine or you could see the inner Airsoft barrel. This gun is juts that realistic. There is Smith & Wesson licensing and marking all over this gun and even the white warning instructions on the right side of the slide. Of course this Airsoft Replica Pistol field strips and functions just like the real Smith & Wesson M&P 9C Pistol.
Very good weight and solid feeling gun for being so compact.
Full size drop out metal magazine.
Nice snappy blowback action.
Excellent fit and finish.
Extremely accurate looking and working Smith & Wesson M&P 9C - Fully licensed..
Rear sight is adjustable for windage.
White dot sights for quick target acquisition
Working trigger safety
Fully field strip-able.
Cons:
Comes with an orange tip not required for Canada.
White dot sights need to be install?
Right side slide catch-release is for show only - non-functioning.
Comments:
Overall the Cybergun - VFC Smith & Wesson M&P 9C GBB Airsoft Pistol as I said is really a wonderful replica in terms of realism in looks and function, I wish all Airsoft guns and Airguns paid this much attention to the details. But more than that, the Cybergun - VFC Smith & Wesson M&P 9C is really well put together and even though it is small it feels tuff and well made. I could see myself using this exact pistol as a backup gun for some future Airsoft battles :) I hope to have the opportunity to review more guns made by VFS down the road...
My Vimeo Video Review for the Cybergun - VFC Smith & Wesson M&P 9C GBB Airsoft Pistol:
All references, photos and video claiming that any item in this review/video looks like a Glock or is a Replica of a Glock in any way shape or form have been removed from this post as requested by Glock "Renzulli Law Firm"
I almost forgot to do my field test review for my WE AK-74UN & WE G18C Tactical GBB Airsoft Pistol and Rifle! I decided to do them both together on this one but I still did my usual full testing for both guns which consisted of my Chronograph, Target and Can destruction along with some high speed slow motion of the blowback action of both guns in full auto mode.
Photo of WE G18C Removed by Request from Glock "Renzulli Law Firm"
Your best bet is to watch my Youtube video and see how both of these WE Airsoft guns perform. Overall they are both rally nice and super realistic, the WE G18C Tactical is definitely the full auto monster here while the AK-74UN is the bull in the China store with its crazy heavy blowback action, it has so much recoil that when shooting in full auto it kind of runs our of steam near the end, not so with the WE G18C as it did not slow down even with the 50 round magazine loaded up!
The WE AK-74UN even with it's crazy recoil holds on target very well in semi and full auto and of course has the superior fps performance. I found when shooting the G18C in full auto, I needed to hold my aim-point low as the blowback and super fast cycle rate wanted to pull the gun up and over my target, same would be true with a real gun so no surprise here.
Photo of WE G18C Removed by Request from Glock "Renzulli Law Firm"
I filmed this video Field Test Shooting Review of my Cybergun VFC Smith & Wesson M&P 9C GBB Airsoft Pistol alongside my Cybergun Tanfoglio Gold Custom which I already posted, both guns performed very well for me. I am supper impressed with the realism of the Cybergun VFC Smith & Wesson M&P 9C and was hopping that the testing would prove this Airsoft pistol to be equally as good of a shooter as it is a looker and I was not let down. It's not going to win any awards for super high fps or tight accuracy but it did a nice job overall and most importantly it worked without any problems whatsoever.
I shot this Cybergun blowback Airsoft pistol using .20 gram Airsoft BB's through my Chrony Chronograph and got just under 300 fps which is not bad for such a compact short barreled GBB Airsoft pistol. I also shot 5 rounds first in semi auto at the target from 20 feet out using a semi rested position (resting on a sand bag up front and kneeling in the back) and the S&W M&P 9C shot a respectable 2 inch grouping. When I switched over to full auto and blasted the last 10 rounds it was pretty much a spray and pray but who cares it was fun and if anyone was standing in front of that they where gonna get hit for sure.
I really like the Cybergun VFC Smith & Wesson M&P 9C GBB Airsoft Pistol , not just because it really looks the part, it also feels solid and well built, everything about it seems to be very high quality and the shooting performance is no letdown either. This may even be one of my favorite Airsoft pistols! Look forward to my upcoming Table Top Review for this very fine Cybergun Airsoft Pistol...
I received some review BB and Airsoft guns and as I often like to do, I made a quick Update Vimeo Video for you. This way I can show them off real quickly so you get at least a bit of a taste of what's in store...
Below are the guns I show you in todays Update Video!
We have added some items to the Canada and US Replica Airguns Stores, most are completely new items and one is a Canada only item we added to the US store!
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.
