The rifle is neither new nor a high round count gun. I have shot at least a few hundred rounds through it without issue. That does not mean it isn't on the edge of failure when clean/lubed, of course.
I was convinced the gas block screws must be loose but everything was tight.
600 rounds dry? More than I would have guessed, I certainly thought it was weird mine choked.
