Thread: Machinist/Gunsmiths Muzzle Threading Query

Thanks for the responses. Wasn't sure whether the relief functioned to allow ensure the suppressor could but against the shoulder without the threads binding. Threads seem good nice and snug and would expect them to be concentric to the bore.

As for the relief radius that makes sense as it removes a stress point I guess what I meant is it kind of looked like the radius ended above the major thread pitch.

How would you tell whether the suppressor buts up against the shoulder on an over barrel style?

Will see how they both shoot these coming few weeks.
