Trigger Pull: The trigger pull on the Umarex Legends M1A1 Blowback CO2 BB Machine Gun is single action only so you will need to charge the bolt for the first shot just like you would on the real steel Thompson M1A1, after that the blowback operation will charge the bolt which allows for semi and full auto shooting. Trigger pull is not very long or heavy.

Accuracy: I have not done my official Field Test Shooting Video for the Umarex Legends M1A1 Blowback CO2 BB Machine Gun but expect to to shoot in a similar manner to the Umarex Legends M1A1 Blowback CO2 BB Machine Gun. Stay posted for my future Field Test Shooting video coming later on.

Build Quality: The Umarex Legends M1A1 Blowback CO2 BB Machine Gun is pretty much all metal other than the stock and pistol grip. Pretty much everything that is black is going to be metal on this CO2 airgun. It weighs in at a hefty 7.75 pounds which is lighter than the real steel version by about 2 pounds but keep in mind the simulated plastic wood grips are a much lighter than real wood would be. Overall the fit and finish is really good, mechanical parts work well and seem to be well machined..

Realism: The Umarex Legends M1A1 Blowback CO2 BB Machine Gun is a 1 to 1 replica of the real steel World War II Thompson M1A1 Machine Gun and is very authentic looking with similar operation. Even the magazine holds 30 rounds just like the real steel Thompson M1A1. The blowback operation will give you a little bit of that shoulder tap but of course nothing like a 45 caliber M1A1. As expected in todays Replica Airguns the barrel is recessed to give it a larger opening and the CO2 screw is hidden well enough. I would like to see at least a real wood kit for the Umarex Legends M1A1 Blowback CO2 BB Machine Gun which would not lonely look even better but also increase the overall weight closer to the 10 pound real steel weight.

Pros:

• Yet another Classic Legends Replica Airgun from Umarex, maybe one of the best to date.
• Mostly all metal design with good overall weight.
• Semi and Full auto select-ability.
• Dual CO2 design for increased shots and less cool down effect.
• High capacity 30 round full size drop out metal magazine.
• Umarex went with less rounds to get away from the double stay configuration of the 50 round Legends MP40 which was not always dependable.
• Great looking replica of the real steel M1A1 in looks, operation and feel.
• Internal bolt blowback will give a bit of recoil feedback feel.
• Simulated wood looks very realistic.
• Recessed barrel for added realism.

Cons:

• Real wood hardware would have been cine and added it of additional weight. Maybe Umarex will offer this down the road?
• Price is getting up there a bit but still worth it if you are an M1A1 fan, imagine what a real one would cost?
• Going to eat up CO2 quickly in full auto mode but you can always switch over to semi auto.

Comments:
Another great Legends product from Umarex, maybe even the best one so far. The only issues I had with the Umarex Legends MP40 was the double stack magazine feeding dependability with the 50 round double stack magazine not always feeding consistently. Umarex went back to a less aggressive closer to a single stack magazine on the Umarex Legends M1A1 Blowback CO2 BB Machine Gun which has a fewer rods but is expected to feed more consistently. I am looking forward to getting out and actually shooting the Umarex Legends M1A1 Blowback CO2 BB Machine Gun when I make my Field Test Shooting video. My advice right now with uncertainties about if and when we will get new inventory is buy now if you are in a position to as I am not sure how long they will last and when we will be able to get more stock.
