  1. excellent barrel 5 Star Review

    Posted by on 8th Aug 2016

    Incredible barrel, just what I was hoping for. zeroed it this weekend, worked perfectly. Gas hole comes pre-drilled and appears to function perfectly, no issues. Sometimes you pay for quality in life, this barrel is quality.

  3. Groups great @ 100 5 Star Review

    Posted by on 11th Feb 2016

    So far i have fired 350 rounds from this barrel have of which where tula .223 55g ammo; the other half being FED .223 and XM855. If any of this information has merit to anyone hear you go. This will be my second buy from GM; first was an 18" SS barrel. I cant reiterate how happy iam with them. I bought a cheap radical arms barrel once and will never look back ever since i started buying from this company, I even get a thank you letter with a sticker weeks after i get my item.

    Anyways check out the pics for yourself.

  4. First AR Build 5 Star Review

    Posted by on 11th Dec 2014

    Decided to build my first AR and found Green Mountain just by chance. Glad I did. Great barrel for the price. I will definitely be purchasing another barrel from Green Mountain for my next build.


  5. Great quality and Service!! 5 Star Review

    Posted by on 8th May 2014

    Looked for the right barrel for my first complete M-4 build. I remember a custom black powder builder using your barrels, So I looked you up and found the barrel with the best features you could ask for. The price was a no brainer from a barrel builder compared to a unknown and unrated company.
    Great accuracy and have smoked several Wild Hogs with this barrel.
