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
