I have used my M240B for 1 game no problems except some nuts & bolts came loose and one which affected the feeding but after that no problems and for the game it worked as it should, the nut that came loose was on metalpart on the ammobox and somehow that affected the feeding.
when i took the gun out of the box and assembled it i managed to slice of the wiring but it came loose on the soldering but no problems, used the echo1 guide videos took the gearbox out and soldered it and made sure it was better then before so no more problems!
