Failure to Eject due to excessive gas port, UPDATE: Problem solved w/custom gas plug

[DeanD]

Did a couple of modifications: polished the chamber using 1500 wet-dry lubed with WD-40 wrapped around a lapping tool and then finished off with a .410 shotgun swab coated in Semichrome polish with the cleaning rod chucked up in a drill motor. The fired cases look really nice now, no scuffs, nothing. Polished a slight radius on the sharp edge on the ejector and put a radius/bevel on the inside. This allows the case to pivot to the right when ejecting, same as you do to a fixed ejector on a 1911pistol or FAL rifle, etc. A lot of AR guys swear by this and it did improve the ejection plus the ejector was digging into the case head with a nasty smear streak and it no longer does that, just rubs through the lacquer coating on the Wolf ammo now. The cycling feels so good now. I was getting stovepipe jams about every 5 rounds and forward ejection, today I fired 80 rounds and it ran like a sewing machine! Every detail thing helped it function better but reducing the gas port from .094" to .063" made most of the difference.



Empty cases ejected about 8-9' perfectly at 3:00 and piled up in a beautiful pile about 3' across. Wolf 100 gr. 6.5 Grendel ammo. Nice!
