  1. Best 223 barrel I have 5 Star Review

    Posted by on 7th Feb 2020

    The accuracy has not changed after 500+ rounds, love the sub 1 MOA at 100 yds. Beautiful barrel w/ Attention to details. I will buy another for the next build.

  3. 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.


  4. outstanding accuracy 5 Star Review

    Posted by on 10th Jul 2019

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


  5. 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.
