Winchester XPR Barrel Nut

[Brakeman]

Good morning troops
Looking to see if you could help me out with a bit of info on the XPR? I'm looking to rebarrel to a different caliber and am trying to ferret out the barrel/receiver diameter, thread pitch and length in hopes of finding a new barrel nut to make this happen.

Have you any info on this?
Would be much appreciated,

Jeff

I had emailed McGowen about a prefit when I had mine and he said it was no problem, that it was basically a M70 with a barrel nut or something like that.
