Just a followup up on this. Gave the chamber a polish and still no luck. Brought it to a trusted gunsmith (former Canadian Forces weapons tech), and he was stumped as well.
It's my guess that, in a straight pull AR, you just don't get the camming force that is required to extract the case from the chamber. It's probably time to put a .223 barrel back on. I've got an orphaned 12.5" barrel looking for a home, so all is not lost with this rifle.
