This is the op rod for the MP-44. It is a combination of the gas piston and the bolt carrier. The bolt carrier provides the cam surface for the bolt to lock and unlock the bolt from the trunnion.
Could you please show us some pictures of the locking shelf inside the trunnion? Approximately what size is the bolt lug/locking shelf connection?
I build guns as a hobby and this information would be very helpful to a design I’m working on.
