I have a Classic Army UMC, i want to replace the gear box, it's right G36 gearbox fit in the UMC?

Well it's a V3 if thats what you mean.

I'm not sure if its a V1 or a V2, but I want to know witch gearbox fit in my UMC.

A V3 gearbox...

Its a G36 V3 gearbox who fit in a UMC? sorry, sometime I feel tard, I speak french and my english go away sometime loll

G36 gearbox is a V3 yes, but it wouldn't transfer over directly. You need a UMP-specific selector plate, nozzle, and probably other parts too.

Trigger, cylinder, maybe a proprietary nonsense bit

nozzle and cylinder head are non standard. the safety plate that also houses the pushpin that locks the front of the gearbox into the lower is also different than g36. The trigger and selector plates are different. I think it uses the same motor cage. The base shell and most of the components are v3.

A fully assembled v3 gearbox meant for a g36 will not drop in.

You could swap all the parts over, but if you can't tell the difference between a v2 and a v3 gearbox and need to ask, well then you wouldn't be qualified to do that either.
