  2. G-M8 mid length rifle barrel 5 Star Review

    Posted by on 5th Aug 2016

    This Barrel was purchased for a personal build and sits on top of a Bravo Company lower, the barrel head spaced to my Windham bolt perfectly with Clymer Go/No go gauges, and the Gas block fit perfectly as well. I have yet to take it to a range but the quality was excellent, shipping was quick.

    Can't beat the quality and the price. I've used Green Mountain barrels for 2 AR builds, accurate and well made. I'll be ordering again soon. Thanks GM.

    Great barrel


  5. Very nice quality 5 Star Review

    Posted by on 16th May 2016

    Just ran 100 rounds through it yesterday for the first time. Had a couple hiccups with failure to fully lock up with the bolt. (2 out of 100). I attribute this to a brand new barrel and bolt getting broken in. My ar is not set up for accuracy but i was getting nice groups with a 3moa red dot site at 100yrds. Fit and finish are excellent! I like the weight too. Not a pencil barrel for sure but lighter than my daniel defense s2w. I would definitely buy again. The shipping was fast and the barrel was well protected on arrival. GM even sent a follow up letter to say thanks for the purchase, nice touch.
