I started with a full 30 rounds. It was locked in. I had to use the release to get the mag out during diagnostics. I couldn't see it but I was pretty sure there was a round in the chamber and that made me a little anxious while trying to work the bolt back and forth at the range bench. Even more so when I brought it indoors to work on it.

With the bolt moving easier now, I'm hopeful the problem is gone.
