I got it. Really think its the right size hole because Liberty makes the barrels. Also finding if I pull back the charge handle and release with an empty mag, even a P-mag, it slaps up into the barrel extension. Doesn't lock open unless I push the bolt catch up.
I already took the Silent Capture Buffer out of the equation and stuck a rifle length buffer spring and buffer in but no help.
Did that and ran 20 rounds of Hornady 123gr VMAX, no change. I also started from screwed all the way in and then backed out 2 full turns. Each time when it didn't eject increased by 1/2 turn each round as recommended by JP. Did that till it cycled but the bolt never held back. Then tried to run 2 bullets and it never went back far enough to snatch up the second round.
So I'm wondering if it's the low mass carrier. I'm going to use my regular Fail Zero BCG tomorrow, swap out the bolt and see if its the Low Mass Bolt Carrier.Then if it still happens off with the Adjustable gas block, take some measurements and if all looks correct, I'll install a regular gas block. It has to be one of the 4 things. I think I might even try a different lower to eliminate the bolt catch but that still doesn't solve the feeding issue....CRAZZY GRENDEL
