Threading AR15 Barrel

[Squirrley11]

I Have a busmast barrel that I was just able to get the fixed flash suppressor off of. Only issue is the barrel is not threaded. Is it a big job to get the barrel threaded and how much do you think this would cost?

Depends on the level tear down and reassemble you ask of your smith, but somewhere between $45-$75 should see the job done.

It's 1/2" x 28tpi for .6" if that helps.
