Field tested a new AR build today. The first round extracted fine, after that, I had to extract each round by cycling the bolt. When fired, the bolt would not cycle. My thoughts are the gas port / tube are blocked, and I'll run a pipe cleaner down there to check it out. When I mouted the gas block, it seemed to have good air flow, tested with compressed air in the barrel. Cases ejected fine with the charging handle. Commercial ammo.
All thoughts welcome. Thanks guys.
