  1. These barrels are amazing 5 Star Review

    Posted by on 24th Mar 2019

    I have now used 2 of these barrels, 1 on an M16A2 and the other on an M16A4 build. Excellent barrels, with great accuracy. The only improvement would be if GM added the .700" turned down area for the first 5/8" just behind the threaded area for the flash hider as are found on military barrels. But that's just me being nitpicky. I will use one on my next 20" barrel build.


  2. excellent barrel for heavier 5.56 ammo 5 Star Review

    Posted by on 4th Sep 2018

    Bought barrel for optimal accuracy for 69 & 77gr bullets. Exceptional accuracy great price.


  3. Very Very Accurate!!! 5 Star Review

    Posted by on 23rd Apr 2017

    No-brains accurate at a 25 yard zero of course. But once I let it go at long distances, this barrel amazingly accurate with my 75gr reloads (Hornady HPBT at 2800 fps)!!!

    I went shooting in a new area so I didn't have any distances measured. I was just shooting at random rocks, but kept note distinct formations of the mountains so I can reference the range on Google Earth. Once I did measured it at home, I was hitting up to 800 yards consistently!

    I bought this to get baseline readings for my M193 reloads and planned to upgrade to a 20" 223 Wylde in the future, but what for what?! It's already a laser!!!


  4. I feel very comfortable with this barrel. Would and have recommended it to others 5 Star Review

    Very pleased with this product and the Green Mountain company. Thank you for a great barrel.


  5. Great choice for Nearly Mil-Spec barrel 5 Star Review

    Excellent quality, outstanding price, fast service and shipping. What more could you ask for? Maybe the option to drill the barrel for FSB pins, that's about it. Highly recommended!
