Type: Air Rifle / Machine Gun. Distributer: Umarex Model: Legends M1A1. Materials: Mostly Metal build. Weight: 7.75 pounds (3.5 kilograms) Barrel: 12 inches - smooth bore steel. Propulsion: 2x12 gram CO2. Action: Internal Bolt Blowback single action. Ammunition Type: 4.5mm Steel BB's. Ammunition Capacity: 30 round full size drop out magazine. Max FPS: 435 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.
