I have a quick question about owners with a surefire muzzle break. I got a 7.62 SF MB installed onto my rifle and every time I go out shooting the crown is filled up with powder. I am just wondering if this is how your crown ends up with lots of powder on the crown, and do you clean it.
(shot 50 rounds and was caked with powder residue, and shot yesterday with 30 and the same thing happened)
