So, finally got the unit apart, and it was a case head separation. The upper, barrel and BCG are OK, the bolt needs replaced, and the charging handle is bent from me "mortaring" it to get the stuck case out.
No more reloads from pick up brass, I guess.
And no more reloads from friends.
I'm not sure about the logic of the statements in
bold above - seems like you're over reacting a bit.
I can't tell from the photo, but what happened to the bolt?
