Thread: Machinist/Gunsmiths Muzzle Threading Query

Have two rifles with threaded Muzzles and was having a look and thought neither looks like what I thought I remembered my old threaded rifles looked like.

One doesn't seem to have a square shoulder and one doesn't seem to have a relief cut.

Is this just different ways to suck eggs or something to have looked at?

I don't know much about this side of things so thought I'd ask the NZHS forum.

Don't know if it matters but ones for a brake and one a suppressor.

Cheers,
Cam
