The saddle ring stud, but for the old original saddle ring carbines. I need to know the size of a chaser tap. I have an old 1903 vintage SRC that has buggered threads in the stud hole, but I think it is salvageable.
(If I'm not mistaken the later production 94s use a smaller stud.)
Edit: I see that I didn't make that clear in my first post. It was late. LOL
