Hi,
I just picked up a 116 chambered in 7mm RUM (factory rifle) from a buddy. It has the 360 degree muzzle brake.
Does anyone know what thread pitch they used for these? How can I find that out? I'm hoping it's standard like 5/8x24.

The Factory ON/OFF adjustable muzzle brakes are threaded 9/16-28". FWIW the Barrel's Shank is threaded 1.120"-20.
Thanks for the info. That's gonna make it tough to change.
Are you sure it's x28 and not by x24? Having trouble finding 9/16 x 28.Quote:

My guess is they needed less thread depth to keep enough material thickness on the larger .308" and .338" bores that these were offered on at one time or another.
You will most likely have to either have the end of your barrel lopped off and rethreaded, or call and talk to some of the bigger brake makers and see if they have a tap to make you one special.
