Green Mount makes one of the best barrels I ever used on a 10/22 receiver. The quality of the finish and design of the heavy bull fluted barrel is second to none. I've used several other (some much more expensive) barrels from other companies on 10/22 builds before and none looked or performed better than this barrel. I used this barrel in a ZK-22 bullpup stock and after breaking it in per Green Mountain instructions, I preceded to start shooting various ammo to find what would shoot best in this barrel. I was amazed at how accurate this barrel is. Shooting Federal, CCI, Remington and Centurion ammo I found that I could shoot 1" inch groups at 50 yards easily with 3 out of 4 brands of ammo. One brand was closer to 1.25" inch groups but that's still fantastic for a .22lr round. Bravo Green Mountain... I'll be back for more!
