I bought this barrel from an estate collection, and it was unfired when I bought it. It was never put on a gun. I took it to the range today and fired 35 rounds out of it and it functioned and shot perfectly. OK, why am I selling it? I had to take my .17HMR barrel off the gun to put the .22mag barrel on. I instantly realized I don’t like swapping barrels. My .17hmr barrel shoots unbelievably well, sub 1moa at 100 yards every time with selected ammo, and frequently shoots .5moa five shot groups if I’m having a good day. The .22mag barrel shoots well as can be seen on the attached photo. I just prefer the flatter trajectory of the .17 and I also have around 1,100 rounds of ammo for the .17hmr. I’ll let it go for less than I paid for it, and I’ll include a new five shot magazine. I’m asking $180 tyd.
