Looks like carbon build up to me. Get a brass wire brush and some bore cleaner and give it a good scrubbing. Some of the gas and carbon gets trapped between the brake and the crown and winds up looking like BBQ grill scrapings. Will do...Thanks guys. |

Looks like carbon build up to me. I agree, it looks like carbon build up like the muzzle break has been on there for to many rounds without a good cleaning. A brass brush should clear that right up. that's what it looks like |

Or a brass carbon scraper. I use one for my 74, it ussually looks alot worse than your muzzle and it works great to get all that crap off. |
