trashman Posted May 23, 2015 Report Share Posted May 23, 2015 Is it just the thread pitch that matters? I'm looking to get a muzzle brake and want to make sure I get the right one Quote Link to comment Share on other sites More sharing options...
FaRKle! Posted May 23, 2015 Report Share Posted May 23, 2015 Thread pitch and bore diameter. Usually they state what caliber they're for though so you don't need to worry much about the 2nd one. Quote Link to comment Share on other sites More sharing options...
trashman Posted May 23, 2015 Author Report Share Posted May 23, 2015 Well yea. Obviously caliber I knew. I didn't know if with some 308 barrels of there were different diameters at the muzzle or not. Thank you! Quote Link to comment Share on other sites More sharing options...

98Z5V Posted January 19, 2018 Report Share Posted January 19, 2018 All the DPMS LR308 factory barrels are 5/8x24. Almost every single DPMS-patterned .308 Win barrel is 5/8x24. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted January 19, 2018 Report Share Posted January 19, 2018 Almost every American rifle, 6.5 to 7.62, is 5/8x24. It’s a pretty safe bet. Quote Link to comment Share on other sites More sharing options...
