  1. 10.5 inch 9mm review 5 Star Review

    Posted by on 1st Feb 2016

    As usual, Green Mountain has hit another home run. This 9mm AR pistol barrel is all one could ask for and more. Great is not nearly a good enough pronoun.


  2. Great quality and customer service 5 Star Review

    Posted by on 5th Jan 2016

    Have been buying from GM for a few years from now and have never had any problem at all. Listing GM barrels as one of our suppliers for our firearms is a selling point.


  3. Good price, Excellent Performance 5 Star Review

    Posted by on 17th Aug 2015

    Installed this barrel in a Rock River Arms LAR-9, replacing it's 16" barrel. Installation was perfect, no adjustments necessary, and performance was perfect. The finish is beautiful, and matches the standard AR black finish perfectly. Priced very well, and I am certainly not disappointed!


  4. Great Barrel 5 Star Review

    Posted by on 26th Jul 2015

    I used this for a build using a QC10 small frame Glock Lower, on. VLTOR upper, it fit perfectly. Cycles and functions perfect, customer service was outstanding. Would recommend them to anyone needing a quality barrel.


  5. Dropped Right In 5 Star Review

    Posted by on 6th Apr 2015

    Great barrel. Dropped right in with no real fitting. Headspace with the bolt was right on It's a great barrel at a good price. Can't speak to accuracy just yet, but if it is anywhere like previous GM barrels I have purchased, I don't think I will be disappointed.
