mine just came in and i have a few problems with it. first, the magazine is a pain to fill, i use a propane adapter and whenever i load it it spurts out propane everywhere, but it does get the gas in for a good 30 shots. i dunno if this is because the plastic of my adapter got warped or its because of the valve on the mag, but im 90% sure its the mag because i fill my WE magazines just fine.
second, sometimes when i shoot, the mag release veryy slightly disengages and causes the mag to slide down and protrude from the bottom a bit so i have to either hold the mag or the right side of the
