Thread: Gunwork incl. Barrel threading in Auckland

I always cut a relief on my threads, when I see one’s without it can suggest the thread has been cut with a die, which is a concern as they should be cut on the lathe. I always insist on having the actual suppressor and cut to achieve a good fit.

As for the shoulder, the minimum I will do is 0.5mm, that being the uncut diameter of barrel is 1mm more than the nominal diameter of the thread……. I prefer more if possible
