Hey,
I was wondering if anyone can help me trouble shoot my problems with my G&G M4A1, I installed a metal hop up unit from G&P and followed a step by step guide online but when I finished and reassembled my gun the fps seemed to be off and some BBs rolled out of the gun so I put the stock hop up back in but this time I painted the lower receiver. When I putting the gun back together the selector switch won't stay in semi and it seems like the gear box has locked up.

Thanks
Lucas
