How much can you manually actuate the mechanism with the side off? I'd watch how the bolt interacts with everything. It should be contacting/tripping a disconnector as it travels forward..

Have you tried asking Umarex for the parts drawing (pdf) for the FA version? Looks like a Gletcher/WinGun oem..

I already took off the side to try and understand how the mechanism works, but all the moving parts hv got quite some tension put onto them. So if you pull the bolt back the internals will either jam or pop out of their hinges.

Tried with some airgun/airsoft vendors for some exploded diagramms or such but no luck so far. And umarex is not providing any details on internals since disassembly voids the warranty which is kinda ridiculous! If i just wanna give the moving parts some greasing i'm supposed to send the gun in for maintenance...
