Well I opened up my gearbox, did some maintenance on it, the gun is a G&G combat machine M16, I was actually quite surprised and pleased with the parts that were inside since combat machine grade is to be said the lower end of G&G.

So back on topic, Open her up, clean the crappy grease, relube the gears with white lithium grease, put some silione oil on the o-ring and it has a very good compression, re-shim the whole thing (it was 't a bad shim job from factory actually.) and close her up.

I then proceed to put the lower on her, grip and motor, only to realise that the selector switch is ''reversed''... In safe position it fires full auto, sami stayed the same, and auto funtion became the safe.. What could cause this? How can I fix this?

Thanks,

Jocelyn
