  1. OUSTANDING! 5 Star Review

    Posted by on 20th Apr 2016

    I used this barrel for a 3-gun build. I am getting sub MOA groups with cheap 55gr XM193 ammo. I am very pleased. The barrel was perfect when it arrived. Very well made, perfect. Green Mountain is my go to barrel maker@

  2. Very nice middle weight barrel 5 Star Review

    Posted by on 13th Jan 2016

    Really impressed with the quality of this barrel. The extension has a stud support added to prevent the extractor from being blown off during a head separation. There is a very nice target crown on this barrel as well. Phosphate finish is very tough, there were no marks visible from the vice jaws after machining the taper pin holes for the FSB. Barrel installed on the upper and head spaced with no issues. With a permanently installed extended A2 flash hider the barrel measured 16-3/16" from a closed bolt face.

  3. Great true Mid-weight barrel. 5 Star Review

    Posted by on 2nd Apr 2015

    I installed this barrel on a new carbine build, it was an excellent choice. Balances better than I thought it would. Fit and finish are exemplary, but accuracy is were this barrel really shines. I was shooting at 250 yards and easily shooting the empty Gatorade bottle hanging from the stand with a 4x optic standing. You will not be disappointed by the product or the service.

  4. I can't believe I got this for such a low price 5 Star Review

    Posted by on 18th Mar 2015

    I finally finished the build with this barrel and took it to the range today. I can happily report that with iron sights and cheap ammo I pulled off MOA or better groups, and that was just the first hundred rounds. I cant wai to see what this can do when paired with a good optic and match ammo! The only thing better than how this barrel shoots is the fact that i got it on sale for $99. Seriousy considering making a video review of this barrel for Youtube!

  5. The usual from GMRB 5 Star Review

    Posted by on 18th Mar 2015

    Great product, great service and great shipping. Spread the word. A world class barrel made in America, by Americans for Americans and sold at a discount by caring, extremely knowledgable people. Hard to beat. This was my second order from GMRB and rarely has a company meet my expecctations so completly. I trust my hard earned money to these guys.
