Home Forums Hunting & Shooting Gunsmithing 1917 barrel thread issues

I was going to ask if it was a numrich barrel.

I just fixed two of these for customers. They sent them out with improper cut threads. If i remember, the groove is too narrow and needs to be widened. Will need to be set up on a lathe and threads adjusted.

They should be 0 050" and they sent them all out at 0 045" or something to that sort. Won't thread onto any action. They also need 5-10 thou cut from the shoulder for headspace and extractor cut done as well.
