In need of a replacement 340 barrel but

[gmlieb]

In the middle of converting a 340 series rifle from 30-30 to .219 zipper. The last "Smith" who worked on it chewed up the barrel nut. Searching the net has been a wild goose chase. Was wondering if anyone had one laying around they would want to part with.

Thank you,
George

Will a standard Model 10/110 nut work? I'm no longer familiar with the 340 nut, been a loooooong time since I've seen one.

Measure the OD of the threads. Find someone with a thread pitch gauge and report back. There may be someone who can make one if you can't find one. I think you should get .860" Diameter and a 18 TPI thread pitch. That number is based on a little internet research so Im am not 100%
