Corrosion under muzzle brake

[LC 6.5 Shooter]

I noticed when I pulled the muzzle brake off a savage barrel there was quite a bit of corrosion at the crown area. Do you guys pull the muzzle brakes off regularly when you clean your guns? I have an area 419 hellfire on my creedmoor and only pull the brake not the adapter. Should I be pullimg the adapter too?

I would be interested to see a picture of what your seeing. I only get carbon build up, have not yet seen corrosion.

I get a lot of corrosion when shooting suppressed. Just take a bronze brush and some CLP and scrub it off. I've neve had any major issues in the crown area directly thought. Is the barrel coated or bead blasted?

Yes it looks more like carbon build up. Corrosion was probably not the correct description.

Does this carbon build up affect accuracy? Just curious to see if I should remove the area 419 adapter and clean

Oh okay gotcha. Yeah, carbon buildup is normal. Like Ozzy said, you can carefully remove it with some carbon cleaner. I use a q-tip with Ballistol and my finger nail, doesn't take very long.

I don't mean this in a smart ass way, but you tell me? If you aren't seeing anything out of the ordinary, I would say it's not having any effect. If you see things getting squirrely, and your groups start to open up/move around I'd remove and clean everything carefully. If you're not seeing any negative effects, I wouldn't stress too much about it.

Easier to keep clean regularly. I run little bastard sometimes a pain to clean

Fill a Solo cup with CLR and put your muzzle brake in it. I do it by leaning the whole rifle against my workbench, muzzle-down in the cup, with CLR filled up to the shoulder of the TBAC brake. 5 or 10 minutes in the CLR and the brake and muzzle will wipe off with a rag and few q-tips. I spent way too much time trying to hand clean/scrub the brake with Hoppes or other carbon cleaner prior to doing it this way.

Biggest reason I do it is the TBAC Ultra to CB brake interface gets pretty gunked up with carbon after a 1 or 2 day match, and is hard to get on/off if I don't clean it every couple hundred rounds.

I never take mine off to clean, the barrel will wear out before the corrosion/fouling does any harm.

I never take mine off, I figure that carbon wont build up in the path of the bullet.
When I do take it off to put on a new barrel it is awfully gunky but I havent noticed adverse effects.

Mine always take a good soaking and a steel brush to clean the brakes even after hours soaking in clr or boretech or just plain carb cleaner, no wiping off to it. But then again they only come off to put on a new barrel.

I don't bother. If you look closely, the crown stays clean because any carbon that is there immediately gets blasted off or is removed when you clean the barrel. The carbon that builds up away from the bore up against the adapter isn't pretty, but it doesn't have any effect on accuracy or performance in my experience.

I don't usually take the adapter off until it's time to toss the barrel and screw it on a new one (anti-seize helps there).

I only take mine off when I clean the barrel with Sweets. I just want to make sure that none of the Sweets gets left behind on the crown or between the barrel and brake.

Makes perfect sense. How often to you clean with sweets

Not very often. This is a .308 so maybe every 5-800 or so
