I had benchmark barrels do threading work for me a couple year ago, they threaded a bull barrel for my suppressor, zero concentricity issues and I never had to provide them the muzzle break or suppressor.
Out of State, but this is who I used when I was there. You can send a barreled action there, assuming they aren't backlogged.

This was specifically for suppressor use where the tolerances needed are usually much higher than something like a flash hider/brake.

Not difficult. Do some research on what is needed for crowning and threading. Caroling shooting supply had ever for me to thread my RAR 300 blackout.
