Need some help please. I'm planning to build a Standard Gun on an old action I have and would like to mimic the 54MS barrel.

That said, could someone please measure their 54MS barrel (from the more typical 22" barrel gun) and provide these 3 diameters:

1) Diameter at the Receiver (the large diameter of the cone section of the barrel that meets the front of the receiver).
2) Diameter of the Barrel.
3) Diameter at the front of the Barrel (the bumped up section that runs about 2 inches long).

Thanks in advance for the help!!

Do you plan on doing all of this work yourself? If not, it will be cheaper just to get a 54ms.

Good question and observation. Yes, doing the work myself as a fun project.

Any help with the dimensions would be appreciated
