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.
