Umarex has released yet another Legends Replica Airgun and perhaps this one may be the most iconic yet, the M3 Grease gun with a history as far back as 1942. It was put into service int 1944 and then the later variant the M3A1 was used in the Korean War. Also make sure to watch my Table top Video for it for specifications and details along with more close up video.
Getting back to the Field Test Review for the Umarex Legends CO2 Blowback Full Auto M3 Grease Gun, as always I like to test each gun out in the Replace Airguns Indoor Sea Can Airguns Range first placing 5 rounds through my Chronograph to find out the real world velocity of each test gun, then I shoot 10 rounds in semi auto at a distance of 30 feet onto a paper target to see how tight of a grouping I can get shooting from a seated and rested position. With full auto Airguns I like to then perform a full auto shooting test to see how it groups in full auto as often times the full auto grouping will open up somewhat as some Blowback Full Auto Airguns do tend to move around a lot more in full auto mode.
For my Power or Velocity test I was using dual brand new CO2 cartages. Umarex does state that the Umarex Legends CO2 Blowback Full Auto M3 Grease Gun will shoot around 450 fps and with my 5 shot test I was able to confirm this and get close to this mark averaging 436fps. The temperature in the Sea Can was around 20 degrees Celsius or around 70 degrees Fahrenheit. Perhaps in warmer conditions I might hit the claimed 450 fps but I was close either way.
For my accuracy test I setup a new paper target 30 feet downrange and proceeded to place 10 shots into it using the peep sight on the Umarex Legends CO2 Blowback Full Auto M3 Grease Gun. I was fairly pleased with a fairly tight 1.5 inch grouping in semi auto. I then switched over to full auto fun mode and with the remaining BB’s I unloaded 50 or so rounds in very short order and as expected the grouping opened up to closer to a 4 inch grouping. This was kind of expected since the Umarex Legends CO2 Blowback Full Auto M3 Grease Gun uses an open bolt system which has a fairly heavy bolt which makes the blowback action more intense, similar to the KWC Mini Uzi but to a lessor degree.
Any time a company puts out another Full Auto Replica Rifle, especially full auto firing, I am 100% in on it. Both Crosman and Umarex have done a great job doing this and the Umarex Legends CO2 Blowback Full Auto M3 Grease Gun is another example of a well thought out and what I expect to be very popular Full Auto BB Rifle. Their Legends series encompasses guns of the later era which I personally really like since they are harder to come by in their real steel versions, so having them available in an easier to acquire version that you can even shoot in your back yard is a win win for everyone. I am also happy to confirm the high capacity double stack 60 round magazine seemed to feed pretty good for me only miss-feeding once during my testing while doing the Chronograph portion but it got back on track right away. If you’re into Full Auto Legendary Airguns then for sure pick one up from us!
Type:BB Rifle. Manufacturer: Umarex. Model: Legends M3 Grease Gun Materials: Mostly All Metal Construction. Weight: 7.7 pounds (3.5 kilograms). Length: 29.8 inches (757mm). Barrel Length: 8 inches (20 cm) smoothbore barrel. Propulsion: Dual CO2 Cartridge. Action: Semi & Full Auto Open Bolt Blowback Ammunition Type: 4.5mm steel BB's. Ammunition Capacity: 60 rounds. FPS: 460fps. Rate of Fire: 1050
Trigger Pull: The trigger pull on the Umarex Legends M3 Grease Gun is fairly light being a single action only trigger. You will have to open the bolt (pull it to the rear) which is located under the dust cover using your thumb but the recoil spring is not super heavy on the Airgun version. I would imagine this would take more effort on the real steel version.
Accuracy: I have not Field Test Reviewed the CO2 BB Full Auto Umarex Legends M3 Grease Gun as of yet but will be making a full Fields Test Review next week to find out what to expect in terms of accuracy on both semi and full auto modes along with velocity using brand new twin CO2 Cartridges.
Build Quality: The Umarex Legends BB Grease Gun is really made with form what I can see is an all metal construction at least on the outside. The fit and finishes feel and look really good and it has a nice balance and weight to it.
Realism: The Umarex Legends BB Firing M3 Grease Gun is based on the actual M3A1 version and looks just like it including the rough welds and simple build. Even the action is Open Bolt which means you have to pull the bolt back using your thumb or finger, then when you release the trigger the bolt moves forward loading a round in the chamber and then acting like the firing pin and firing the gun which in turn uses the pressure to cycle the bolt into the rear position ready to fire the next shot in either semi or full auto mode.
Pros:
Yet another Classic Legends Replica Airgun from Umarex.
Virtually all metal design with good overall weight.
Price is very reasonable for all metal replica machine gun in an all metal construction.
Semi and Full auto select-ability.
Dual CO2 design for increased shots and less cool down effect.
Super high capacity 60 round full size drop out metal magazine. (hopefully it works well)
Great looking replica of the real steel Grease Gun in looks, operation and feel.
Internal bolt blowback will give a bit of recoil feedback feel.
Uses a genuine open bolt system.
Recessed barrel for added realism.
Cons:
Sights are non-adjustable.
Hopefully high capacity magazine feeds consistently?
Selector switch under frame is not authentic but does allow for semi, full auto and safe modes.
Comments:
The Umarex Legends M3 Grease Gun is yet another great addition to not only the Legends Series of Umarex Airguns but also their Full Auto BB Rifle lineup! I am hoping the 60 round magazine feeds properly as double\ stack 4.5mm BB Rounds don’t always feed as well as Airsoft BB’s do. I guess we will find out when I make my Filed Test Shooting Video… That said the M3 Grease Gun is an excellent Replica of the real steel version with an all metal build and even a true to form open bolt blowback system. I really hope it performs well so I can recommend this Airgun, on first impressions and simply holding and looking around this BB Machine gun I am impressed so far.
My Table Top Video of the Umarex Legends Full Auto M3 Grease Gun:
In this Preview Unboxing Video I take a look at three new products just listed in our Replica Airguns Store. Two are products from Umarex both being CO2 4.5mm Steel BB and one is a CO2 powered KWC Blowback Airsoft Pistol. I don’t go into a ton of detail in this video but go over what is listed on the box and a quick walk around of each product.
First up I show off the KWC DE L6 CO2 Blowback Airsoft Pistol, it is much like the Cybergun Desert Eagle L6 I reviewed but without the orange tip and with notched pistol grips, also all back which is classic and looks great. This Blowback pistol shoots 6mm Airsoft BB’s at around 360 fps and has a full size dropout metal magazine that holds the CO2 along with 21 rounds.
Next I showcase a rather entry level 4.5mm CO2 BB Pump Action Rifle called the Umarex NXG Pump Shot that is a mostly plastic lighter weight build perfect for smaller or younger shooters. It uses CO2, shoots 4.5mm Steel BB’s and comes with a drop out 10 round rotary magazine. You will have to pump it before each shot but this makes the trigger fairly light.
Lastly but perhaps my favorite in this lineup I take a look at the CO2 4.5mm Blowback Umarex Legends M3 Grease Gun. Just like the real steel .45 caliber Grease Gun it is capable of full auto and also shoots in semi auto. You will find a full size drop out metal magazine that holds two CO2 cartridges along with 60 4.5mm steel BB’s. Thats a lot of rounds!
