I did the mts class recently and burned through 400 rounds in a few hours (easy to do with multiple 15 rounds of fury).
Everything ran fine, much better than the guy with the sig and another guy who somehow had no gas pressure to cycle the bolt.
I never had a bolt so carboned up. It was really dry and went all the way to the bolt itself
I spent a couple of days putting bore cleaner on it and wiping and nylon brushing but there's some hard carbon left near the gas rings on both sides. It's a nib bcg so it should clean easier.
Anyway: should I care? If so, what to do next? I've heard different opinions on scrapers.
