Threading Question?

[reuben22]

I have a 18 inch fluted Sabre barrel. It is threaded in 9/16x24. Could a gunsmith turn it down to 1/2x28 without cutting the barrel back. I want to put an AAC device on it for QD suppressor. I see they make a 30 caliber one with 1/2x28. I can not shorten the barrel because of the flutes. Let me know what you guys think?

it should be possible but i would probably just get an adapter http://www.trosusa.com/Adapters/Adapters.htm or open up the threads in the qd attachment both of which wouldnt risk messing up the barrel

18 tooth or 51 tooth? Either way:

Thanks for the replies. I kind of want to use the 51t brakeout.
