Also, at a minimum, the 80% case capacity with H-!!0 is a flag for inconsistent ignition. It's good to get that out of the way.
For all we know the ejection port door spring is installed backwards and it's locking back on the mag follower. No offense to Haribol, because I've mistaken the latter and like to joke about the former.
You pretty much just need to pull the charging handle on a round and see if it'll eject to get a feel for a broken ejector or extractor. The AR system is very robust, but we need to ask that question too. Haibol said they looked normal. But now we know a lot more about the players.
