I am curious whether the carbon build up on the crown under a muzzle brake or suppressor reduces accuracy, and whether you guys are cleaning it to the metal every time or not and how you are doing it.
Crown Carbon Build Up

Unsure if it helps much but it gives peace of mind.

i have both brass and bronze bore brushes as well as nylon i dont use them very much as they only loosen carbon don't really do anything for the copper, you could also just put a dab of kroil on the carbonized crown and it will proably come off without any real scrubbingPunctuation is for the weak....

I don't know if it needs to be done every time, but Boretech c4 carbon cleaner will make short work of it. You can run a tight patch from the breech, and stop it just as it gets to the muzzle. Now stand the rifle up and dribble enough cleaner on the muzzle to cover and let it soak a couple hours.

Kg carbon cleaner or kroil and a brass brush. Usually the kroil will loosen it enough to wipe most of it off. If I have a heavily carbon fouled barrel I soak in kroil, couple passes with bore brush then patches. Kroil is the shiznit as some would say!!

Thanks for all the replies. The brass brush absolutely worked. I used montana xtreme let it sit for about a minute then used the brass brush and it was gone in less than a minute. I'll try Kroil next time.
Just FYI, Montana xtreme is very strong, I recommend taking a deep breath before you open the bottle and try not to breath in the fumes. Also, make sure your head is away from the mouth as the vapor will burn your eyes.
