Re: WTF happened to this muzzle break?
My guess, getting beat up by clean rod with a patch jag on it. By the end the bore is not supporting it and it's banging into it.
Just a guess.

Re: WTF happened to this muzzle break?
Remember, a muzzle break is designed to direct the muzzle blast sideways and backwards so that it’s energy will cancel some of the recoil of the gun.
In order to do this when the bullet arrives at the port, it acts as a seal for the muzzle so the blast following it will go sideways, so there is a lot of fire and brimstone going through this area….

Was this brake coated? It has a line as if the coating is being blasted away.

Re: WTF happened to this muzzle break?
Looks like gas wash to me, but what's puzzling is that the primary blast baffle has less damage than the second/last one.
Is that on a supermagnum or an AW50?

Re: WTF happened to this muzzle break?
Doesn't the first baffle have a larger diameter hole, by a tiny amount? I once read that it improves effectiveness of the brake to do that. In that case, there isn't as much sealing effect and thus not as much erosion? Just guessing.

Re: WTF happened to this muzzle break?
Could be the blast and/or hot gas as mentioned above, but there may also be a contribution from corrosion due to the carbon and salt buildup. Kinda looks like it's actually been eaten away to some extent.

Re: WTF happened to this muzzle break?
Unless one is overly concerned about appearance, one can have a muzzle break titanium nitride coated. If you glass bead the brake beforehand, it will not be extremely shiny and will have a much greater degree of tolerance against blast and particulate matter.

Yup that is gas cutting and heat damage. Most of my high mileage breaks have similar issues.

Thanks to everyone for all the replies.
Matt- how much "mileage" would you estimate this break has? And how does this wear effect performance?

Re: WTF happened to this muzzle break?
My PWS FSC556 looks way worse than that after only 500 rds. The metal closest to the muzzle end actually eroded.

Re: WTF happened to this muzzle break?
Its gasses my TRG break looks similar to this. Its only cosmetic and has no effect on the performance of the break or rifle.

Re: WTF happened to this muzzle break?
Looks like erosion from gas and heat, try to champfer any flat surface bore/baffle holes if you can. That will save your brake.

Re: WTF happened to this muzzle break?
While I havent seen this on any of my muzzle breaks, I have seen this on my US made AK gas piston. The edges get eaten away from the gas like that.
Is this mostly a design issue, or is the steel not the best for the job?

Re: WTF happened to this muzzle break?
90 degree edges take a beating on any parts that are exposed to hi/hot pressure. On parts that can be nitrided, thats a good way to prolong life or the champfer on brakes. I haven't seen stainless vs carbon in blast wear tests, can't coment on that.
