  1. Wish they made this barrel in. 308 / 762. 5 Star Review

    Posted by on 29th Mar 2019

    I have this barrel in black. Awesome barrel. You do your part, and the barrel will do its part. Wish Green Mountain would develop one chambered for. 308 / 7.62.

  2. Very disappointed 2 Star Review

    Posted by on 22nd Mar 2019

    I held off on this review until I had hundreds of rounds down it. Tried over 20 types of ammo including several match grade varieties. 1.4" is my best group at 100 yards trying all these different brands, bullet weights, and so on. I got AR-15's that cost less than half of what this one does that shoot much, much better. For what this barrel cost I expect sub MOA.

  3. Deadly Accurate 5 Star Review

    Posted by on 4th Jan 2019

    I bought this for a hog hunting build. I mainly hunt at night with green lights. This barrel has been deadly accurate for me. Every animal I have harvested was taken with a head shot and have taken every animal I have shot at. I offer my highest recommendation for this barrel.

  4. Outstanding accuracy 5 Star Review

    Put this barrel in an Areo Precision enhanced upper, will shot sub moa with various ammo. Sub half moa with IMI 69gr match, and will do it every time - 5 shots at 100 yds - 1/2 inch. Very impressive.

  5. Great shooting barrel 5 Star Review

    Posted by on 16th Jul 2018

    I was building an upper for coyote/varmint rifle and came across this barrel. After sight in, I was clover leafing at 100yds before any barrel break in... I'm assuming after some more time will only get better. No feed issues, all is good!!
