Standard threading for large bore suppressors

JohnQuixote · November 26, 2007, 10:17 AM

I'm looking to thread the barrel of a .308 that I've got in preparation to receive either a flash guard or a suppressor. Is there a standard threading for these accessories?

There isn't really a "standard" pitch per se. Most platforms have standard pitches, the AR for example, but suppressors don't tend to have standard pitches. I know that there are .30 cal cans out there that come 9/16x24 and 5/8x24, and then AAC makes .30 cal cans that are QD for their custom flash hiders. Then a lot of manufacturers ask you to specify a thread pitch before they build the can to your specs. If I were you, I'd research which can I was likely to buy, and then have the barrel threaded accordingly.

U.S. Standard for 308 is 5/8-24.
