Copied in detail from an original example. Shown with an original in the photos, if you cant tell which is which, that's the point; they are good. The threads are M14 X 1.5 which should fit nearly all original G43 examples although there could be some out there with an awkward thread pitch. We have never come across an original barrel with any other pitch thread except for the ones that have been bubba'd after the war.
This is a replacement nut NOT a blank adapter.
