Tried the search, but didn't quite find what I'm looking for…
I have a somewhat standard set-up I'm trying to diagnose a jam situation on…
Build: 11.5" barrel (BCM), carbine length gas system, low pro gas block, m16 bolt, mil spec buffer tube/spring, car buffer
Problem: Short stroke looking jams, with failure to ejects.
It seems like the rife is short stroking. When I load and fire a single round from the magazine, the bolt locks back.
Am I missing something else here, I though short stroke should not lock the bolt back.
