There are a few barrels for sale on the Zero Percent page.
I was hoping to get a bunch of barrels done so I could sell them, but I broke the only chamber reamer I had that made a nice smooth chamber. I tried a Clymer reamer, but it was so poorly ground that the surface finish was unacceptable. I also had a Pacific Tool and Gauge carbide reamer that was cutting very smoothly before I broke it. Anyway, I have some more reamers coming next week so I can get back into finishing the barrels.
