I bought a 16" upper in 7.62x39 from them at Market Hall. It came complete with the modified bolt and firing pin required for the Russian round. Accuracy is nothing to write home about, but I've only shot steel-cased cheapo ammo through it. I'm sure better quality ammo would achieve better accuracy. I've never had a misfire, and it's a fun gun for plinking and goofing around. A coyote and several pigs have succumbed to the rifle as well.
