Trying to get my Surefire muzzle brake off (.223), and I believe it was installed w/ rockset (I think this because I remember the guy who built it for me said that I wasn't going to have an issue with the brake coming off, and because when I torched the device it started smoking). Last night I put the upper in a vice, and torched the absolutely crap out of the end of the barrel... or at least enough that it didn't make me feel uncomfortable. I can't get this damn thing to budge.
I don't have an upper vice block, so I simply used two aluminum plates on each side so that it wouldn't mar the rail, and used a propane torch on the muzzle device until it started losing its color. Had it tight in the vice, another guy keep extra tension on the upper while applying more heat, and I had a wrench w/ a decent sized cheater bar, and the damn thing would not budge. I've seen tons and tons of people say that they've had no issues getting devices off that have been installed w/ rockset. The only other thing I can think of to do is get a legitimate upper block and an armorers wrench (though I don't see the wrench making a difference here, the tools I was using fit perfectly snug on the device...19mm wrench), and go to town with an acetylene torch that I have, but I'm concerned that if I use that heavy of a torch, it could warp/damage the barrel, and that's the last thing that I want... I currently have the end of the gun sitting in a pot of water and intend to leave it for a day or so, I've seen a few people say that can help out with breaking down the rockset.
Any tips/tricks/ideas? I'd rather not pay somebody to do something that seems so simple, but if that's what it comes down to then it is what it is.
Swapping from a SFMB to a SOLGW Nox, trying to make it so people don't hate me so much when they're shooting next to me, and so that it doesn't make such a massive fireball..
