  1. Top Notch Barrel 5 Star Review

    Posted by on 6th Aug 2019

    I am very impressed with this barrel. Extremely accurate with a variety of factory ammo. This is in fact a real tack driver.
    I used a lead sled to sight in a Leopold scope at 50 yards to start and after 5 shots I thought I was missing the target. On a lark I set up at 100 yards and the spotting scope revealed the truth. I had a less than .5 inch group. Very happy with this barrel and will definitely buy more. The rifle sells the barrel all by itself. I had several inquires while sighting it in. So many I began to feel pestered a bit. WELL DONE G.M.

  2. outstanding accuracy 5 Star Review

    Outstanding barrel great fit and finish and more accurate than i can shoot.

  3. Shoots even better than it looks. 5 Star Review

    Posted by on 2nd Jun 2019

    Shipping was fast. Top quality Machining, fit and finish absolutely perfect. Started shooting it with 55 grain to sight it in and work all the way up to 77 grain Sig Sauer performance ammo. Finally settled in at 75 grain bthp Hornady match. Not much difference from 73 grain to 77. Under 3/4 MOA. My first Green Mountain barrel and definitely will not be my last.

  4. 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.

  5. 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.
