System 8mm Bearing Complete AEG M4 Gearbox Ver.2 Rear Line


Nice gearbox. But doesn't have that High fps but I didn't need the fps because my motor isn't that powerfull. It has like a M90 or M100 spring in it. If you were going to upgrade something in this I would say first the piston and piston head because they not that great. And then rewire it because the wiring is pretty poor but is ok for people not that much into airsoft. But Mainly it look just like the picture. I do not regret buying it.
