"Bought this gun a couple weeks ago. I currently use a 10.8v large type battery in it and it is a complete beast of a gun. It can run all day on a single charge, and with 3500 bbs, can keep people suppressed for a long, long time. It is rather tiring to use for extended periods of time, due to the length and weight. I typically set the front of the gun down on to of a wall or sticking out of a bunker to act as a sort of MG nest. The magazine on this one has a special function where it only winds when the trigger is pulled, so you do not have to hit any buttons to keep the bbs flowing.
The only con I have found so far is how the magazine hanger is constructed. It looks as if it was spot welded in 4 spots, and after the second use, the welds already broke. I currently have no way of attaching the magazine to the gun, and am in the process of fixing it."
