  1. 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!!!


  2. 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.


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

    Posted by on 11th Jul 2016

    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!


  4. I'm very satisfied 5 Star Review

    Posted by on 2nd May 2016

    The barrel arrived in a timely manner. The price was excellent. The barrel came coated with oxidation protection. It fit with my upper receiver perfectly. If I need to get another barrel (and I plan on building another rifle soon only 16" this time) I will definitely be purchasing from Green Mountain!

    Once you get this thing zeroed in, theres nothing you cant reach out and touch with a nice 77 grain bullet.
