Im pretty sure it is. It unlocks by hand fine but doesnt seem to be enough recoil. Probably something binding somewhere. Gonna swap parts out with my other gun to see.
And that part seems like a funny addition when the original gun had a bolt lock back mechanism already (for single fire mode).
Ah that makes sense. My first build I never used one and it ran fine without so I wasnt sure what its purpose was. This second build is kicking me in the pants lol. When I fire it, the bolt doesnt want to unlock, so barely moves back.
Many thanks man. Again, awesome build thread!
Great thread! Can you post pics of the "bolt stop"? The little rivet that goes on the LHSP near the top over? I cannot figure out which way the notch in the rivet is supposed to go. Thxs!
It is this guy:
