Is it possible to re-thread a 5/8-24 carbon barrel?

[shields shtr]

I have a few Carbon barrel rifles that were...(custom threaded) for the Thunderbeast Brakes for the thread over brake style TBAC suppressors. By this I mean the threads were "timed" so to speak so when I threaded the brake on they were perfectly timed without the use of the crush washers to align the brake. Interestingly, by doing this for whatever reason it has made other 5/8-24 adapters useless. They will thread on about 3 turns and then a hard stop.

So, can you "erase" the current threads on the barrel and rethread to a "standard" 5/8-24? Obviously, can't cut the carbon barrel down.

Going to need a picture but I think it’s unusual you would have such little thread engagement

I wonder if it was thread for a different pitch. Timing a muzzle brake does not normally change a 5/8x 24 thread.

Sounds like whoever threaded your barrels was doing a “thread to fit” pitch dimension. It’s not hard for a competent gunsmith to put the barrel back in the lathe and pick up the current thread. He simply shrinks the pitch diameter until the thread is in proper specification.

This…Fairly simple job for any decent smith.
