After about a year of gathering parts, I finally built this rifle and test fired it. Unfortunately, it seems to be under-gassed. The rifle will fire, but no more than 5 times in a row, will often not strip a round off the mag, and it will not lock back on empty. It is ejecting spent cartridges. My biggest concern is how to validate whether or not it was the gas tube installation or if the pinned gas block is the culprit, in which case I would have to send it back to Centurion arms.
Relevant build info:
Aero upper, lower, and CBG.
16" Centurion arms mk12 mod H barrel w/ pinned gas block (was assembled) but I installed the gas tube as I built it.
Geissele Super 42 w/ H1 buffer
Perhaps I can get some feedback on how to properly troubleshoot it? Anything helps!
