  1. A well made barrel 5 Star Review

    Posted by on 1st Feb 2017

    Wanted to build a retro A1 Vietnam style AR and was happy to find the barrel I needed for my project at Green Mountain. Authentic, well made and accurate too.


  2. Excellent product 5 Star Review

    Posted by on 30th Jan 2017

    Recently purchased an A1 barrel for a retro build. Outstanding service and barrel looks and performs great. Installed on my old Colt kit with no problems. Highly recommend Green Mountain to anyone looking for a quality product at a fair price.


  3. M18 Barral 5 Star Review

    Posted by on 25th Jan 2017

    I am probably one of the few people who have a NOS M16 surplus barrel, had it for over 20 years. The Green Mountain Barrel I just received is not just a Repro., it is a far more high quality part which makes the original Colt barrel look not so great as it did before! The GM barrel has nicer machining and most likely is the same as the first production M10 barrels where. The Chrome bore and rifling could be no better. The price is very low for a part so nice.


  4. Great Product 5 Star Review

    Posted by on 25th Jan 2017

    Was so happy to find this barrel to complete my M16A1 build. Turned out great and barrel was spot on and perfect, only thing that would make this the ultimate would have a pinned front gas block. Was able to buy a set screw front gas block to complete the project. But all in all great barrel, great company.


  5. great! 5 Star Review

    At this point in time as I write this I haven't gotten around to complete my retro build, but so far everything fits nicely. Green mountain did a nice job.
