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. We have imagine this would take more effort on the real steel version.

Accuracy: For our Power or Velocity test we were 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 our 5 shot test we were 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 we might hit the claimed 450 fps but we were close either way. For our accuracy test we 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. We were fairly pleased with a fairly tight 1.5 inch grouping in semi auto. We then switched over to full auto fun mode and with the remaining BB’s we 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.

Build Quality: The Umarex Legends BB Grease Gun is really made with form what we 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! We are 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. We guess we will find out when we will make our 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 we can recommend this Airgun, on first impressions and simply holding and looking around this BB Machine gun we are impressed so far.
