When I get around to playing with it I'll use bursts instead of just dumping the mag and letting the air fizzle out. Haven't put air to it yet, but cock and shoot definitely has a bit of kick because of the heavy bolt. It's going to be fun. I had to order an extra mag also.I wound up ordering the MP40 and the beretta with an extra mag for the beretta. Should arrive on the 6th.
I liked the uzi but couldn't get past the sputtering at the end of firing an entire mag in the video. If it had twin air cartridges it would of been a done deal.
