Anyone know what thread the Barrel stud that threads into the receiver might be? I need to make 1 for a rebuild. Also just saw a 44US listed on another website at $989 wow!
from what I see on a spare one, on the calibers it is .3125, 5/16 by 32tpi. It's such a short threaded post, it was hard to get a good reading under the magnifying. It also has a slight taper on the end. Thats the best I can do for you.
