  1. Really Nice Barrel 5 Star Review

    Posted by on 19th Jul 2021

    The barrel looks great. The quality is really nice. I loaded up some 73gr ELD-Ms and went to the range. After about 10 rounds the groups started tightening up. I was able to put 10 more shots inside of an inch at 100 yards. So far, the furthest I've shot it is 500 yards. I can tell it's going to be a good shooter. 2 liter water bottles at 500 with a 6X optic is pretty good. Thank you for the barrel.


  2. Absolutely Worth It 5 Star Review

    Posted by on 26th Apr 2021

    This barrel is amazing! As a former quality engineer for a leading firearms manufacturer, I have seen quite a bit of good and bad products.. Fit, finish and quality are exceptional on this barrel. No poor machining, or defects to be found. I bought this barrel to replace another 18” barrel I tried to use for a while, but velocity and accuracy were disappointing. That barrel was from a big name in high end ARs, but it did not live up to the hype. This barrel right out of the box met or exceeded both my initial accuracy hopes (sub MOA out to 400yds) and velocity being nearly 100fps higher than my old barrel! I know accuracy will even improve more over time and with the the proper velocity this gives me, I can reach past 600yds out to 800+! I fully intend to buy more barrels from Green Mountain!


  3. Very accurate 5 Star Review

    Posted by on 11th Jan 2021

    I have been looking at barrels with these spec's for awhile for a build I have been doing. We finished the build this Christmas and were blown away by the accuracy. After initial shooting this is the first barrel that truly needs a scope to fully appreciate its capablities.


  4. 1 MOA with Armscore 62grn 5 Star Review

    Posted by on 4th Jan 2021

    Zeroed with a 1x6 LVPO the other day, first time I took it out. Shot a ~1" group @100 with Armscore 62 grain, and a ~2" group @100 with Wolf 55 grain steel case which cycled perfectly using a Carbine weight buffer and spring.

    Good barrel, good price, would buy again.
