I have one of those slanted muzzle brakes and while shooting last Saturday it blew apart. There was no real damage to the shooter or the rest of the firearm. The threaded part stayed on but the portion that extends beyond the muzzle was blown apart. We had about 400 or so rounds down range when it happened and the only thing I can come up with is that it heated up and then deformed a bit causing a slug to catch it. Any other ideas as to why this might have happened? I was planning on putting a JTAC 47 on it but now I'd like to wait until I know if this was caused by a malfunction in my gun or just a faulty muzzle brake.
