308 Heavy Barrel Thread pitch question.

**Oneraggedhole** · 06-23-2023, 10:58 AM

Good day!

I just purchased an Axis 308 with a 20” heavy barrel from one of the gun trading websites here in Canada in new unused condition. It has the old style stock, but it has the accutrigger.

When I went to thread on a 5/8 x 24 brake, it wouldn’t fit..

Can anyone confirm, Did savage use an 11/16 x 24 thread pitch on these? And if so why?

thanks

Actually, Savage has used 9/16-24 as well. Is the threading too large or too small? 5/8” is .625”. 9/16” is .5625” Do you a Calipers to measure? You’d be able to tell right away.

yea, even some inexpensive ones will get you close enough, as long as they are damaged.

The Bear Hunter and Long Range Hunter both had 9/16x28 threads in their on/off style muzzle brakes if that is the ones you were thinking of.
