  1. Excellent barrel 5 Star Review

    Posted by on 30th Mar 2017

    The fit and finish were excellent when I unpacked it, the chrome lining is very nice and the barrel extension is of excellent quality and has m4 feed ramps that indexed perfectly with my upper. I can shoot about 1 MOA with a 3x magnifier on my Micro T2, with a scope I would expect .5 to 3/4 MOA. Overall the barrel is excellent and is right on par with my BCM and Spikes Tactical barrels. The quality difference between the BCM and Spikes Tactical barrels are non existent and they are made from the same correct mil-spec materials and the chrome lining in them is of the same quality, fitment on the upper is the same and the only difference is price. I would definitely buy these barrels again.


  2. Great Combination of Quality and Price 5 Star Review

    Posted by on 12th Mar 2017

    This barrel is for a rifle I built for my son. It is the 5th or 6th Green Mountain Barrel I have purchased. There is a reason I kept coming back - good service and great products. This particular barrel zeroed quickly @ 50 yards. My son put the last 5 shots into a group the size of a quarter with one called flyer from a rest. Spent the rest of the morning having fun without a booble. Pretty much what I've come to expect from GMB's.


  3. High Quality 5 Star Review

    Posted by on 20th Dec 2016

    I'm happy with the two GM-M8 bbls as well as the SS bbl that I've purchased from GM. 1" groups with standard PMC 55 gn ammo works for me! Most companies don't even manufacture barrels. They slap their name on it and raise the price double the price of the GM barrels. I was impressed by the quality of the bbl. The chrome chamber had a mirror finish! I'm telling my buddies to buy GM and save their money on all the "tacticool" hype barrels. Great customer service too. Thanks guys!

    The accuracy of this barrel is phenomenal, price point is excellent and is definitely up to par with High priced barrels. Excellent quality barrel for a great price.


  5. 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.
