Check out my muzzle...

[eyekahn]

So I was removing my brake and getting my rifle ready for cerakote and bedding when I noticed my muzzle looked like this! Ive never seen this before. Is this normal?

pictures are pretty fuzzy, what are we looking at?

The six bulging grooves in my crown. I never noticed them before I ran a brake.

Are they actually grooves?

Looks to me like its a build up of carbon in some spots and a lack of carbon in others, causing the illusion of a depression.

Yea it was carbon I got back in there with a more aggressive cloth and it all came off. Thats normal for a brake to cause carbon to build up like that right? I'm new to all this stuff...

yup. keep shooting and it will just be a big glob. I just took the brake of my .308 to look at the crown can't see much but about a 1/16" layer of gook (see Fletch) built up on the muzzle. Still shoots better than i do.

Good, I figured it was just carbon. I do not have experience with brakes but carbon buildup is VERY normal with firearms, if ever you get the chance to clean a GPMG that has fired a dozen boxes, you'll learn what 'carbon build up' really is

Haha yea I'm used to carbon build up but never really thought it would pattern on the muzzle like that. Good news! Thanks guys.

That isn't nothing several years back Zac Smith posted a picture or two of one of his AI barrels that had serious growths on it. It was almost comical... I try and keep mine cleaned off to help relieve my OCD haha
