  3. Just what I was looking for 5 Star Review

    Posted by on 25th Jun 2020

    I saw this barrel in my search to find a heavy AR barrel to match my Yugo M72's heavy barrel. The AR would be my Dad's and the Yugo is mine. It is a very close match. I built the rifle just like in the picture. It looks awesome and my father loves it. Very accurate, nice coating and great service. And the letter and sticker is a nice touch as well.

    Well made great finsh with attention to details. Very clean rifling and great coating on outside. I have a binary trigger so it helps with cooling and lighter than a bull barrel. I recommend trying green mountain for your next build

  5. Beautiful barrel but ? 4 Star Review

    For my uses I would give it a 5 star rating if it had a 1-8 twist it would be nice if Green Moutain would consider this. The workmanship is very good and it seems to shoot best with heavier 75 & 77 gr bullets.
