Hi guys! I just bought a Kwa M4 and the gun dont shoot the gearbox cycles well but theres is 1 out of 10 bb that come out. I opened the gun noticed that the air nozzle was loose so i opened the gearbox the plastic piston head was broken in half so i took my scar's piston head and put it in the gear box and reassembled everything.I have the same problem...

I think there is more than 1 issue with the gun I think the previous owner broke the pieston head from dry firing. I checked the hop-up unit with a mag and the bb goes trought so i dont think it is a hop-up issue... what do you guys think?
