I have a home build thats short stroking. Barrel is a .223 wydle Green Mountain 22" stainless H bar, rifle length gas system, .086" gas port. A2 stock with rifle length factory buffer and stock spring. Buffer spring is right length. On the last round in a mag the front of the carrier catches the mag catch, brass ejects at 3:30, sometimes it will eject a round and not pick up another. so I know its short stroking.
I tried a different lower, BCG, mags, still does it. Gas rings are good. Doesnt matter reloads or factory ammo. Gas block is aligned, checked all that with calipers. The gas key was leaking a tiny bit. I put loctite on it and torqued it down, havent shot it yet since doing that. Carrier doesnt drag on gas tube. This is what the barrel looks like under the gas block. Gas block is a Brownells low pro, looks to me like it doesnt seal up worth a crap.
