you don't want to do any cutting? what about recrowning it and fixing the last bit of threads if needed or even recrowning it down just past the screwed up thread? (no pun intended haha)
You may not want to take any length off or he'll have to deal with it being an SBR. You could counter-bore it about 1/4" and that would take care of it.Bob -- send it to me. I'll lathe the end off and re- thread it.
I have one of these tools, they work great. I wouldn't worry about the overall length if your only removing material to where the damage starts. If you start by lopping off an inch and rethreading then I might worry, but only removing what you need there shouldn't be an issue when the muzzle device gets reinstalled.Hello Gunco,
Brownells sells a neet little tool that recrowns barrels using a drill. It has a guide bushing to keep things centered nicely. Hey, their address is at the top of this page !!! What a coincidence !!!
I have one of those too. Worth every penny. Unfortunately, in this case just re-crowning may not work. Counterboring may be the only option, if removing material from the end of the barrel drops over all length too close to 16" for comfort (I like to leave at least 1/8" extra on all of the barrels I have, for my own peace of mind).Brownell's also has a hand-turned crown cutter that uses a pilot to center it. I have one, and it works fine for stuff like this.
