The title says it. Does anyone know what the thread size is on Rossi 92 barrels?

13/16-20 TPI if I remember correctly, or that may just be the original 1892
It would be a 20.6 x 1.25 in metric, which I'm sure would be rounded to 20.5 x 1.25.

I'd check in over at Ranch Dog's http://www.rossi-rifleman.com/

or http://www.stevesgunz.com/ (http://www.rossi-rifleman.com/)


Ah, new I'd seen it before

Good thread, Google it popped up for another thread pitch and I saw Rossi 92. Not many work on the Rossi but I make 256wm barrels for them and work on them a lot so thought I’d pad the list.


Rossi 92
All threads are metric 60 degree, all other measurements of the guns are inch just like the Winchester it’s a clone of. Rossi has the cartage lifter detent cuts in the receiver wall where the original Winchesters have these cuts on an apron attached to the left guide rail. So other than the metric threads, different detent cuts, and bolt safety on newer ones Rossis are a direct clone of the early Winchesters.

Barrel thread is M19x1mm, very fine. So fine it's a booger to cut well on a lathe, it's like cutting a 3/4"-40tpi thread.


Winchester 92
.809x20 (same as the 94) and a cheap stock 13/16-20 tap works great to open/clean a receiver, (13/16-20 is .8125” major .0075” bigger diameter) when re-barreling even if using an .809-20 threaded barrel . . . You can just about turn the 13/16 tap in there with your fingers but not quite.

Thanks Artful, I had already tried Steves Guns but got no reply.
