  1. 1ST AR build. 5 Star Review

    Posted by on 6th Sep 2017

    Recently finished my first build. When asking around about barrels GMRB was recommended to me. after reading reviews on not only the products but also the customer service and the company standing behind their products I decided to try my luck. i have 200 rounds through the rifle so far and the barrel shoots great, looks good under a free float and i have also been very impressed with the green mountain's service and follow up. highly recommend.


  2. Quality is there 5 Star Review

    Posted by on 20th Aug 2017

    I purchased this barrel over one month ago and just got the rifle together for a test at the range. I shot several rounds at 50 yards using American Eagle 55 grain fmj and then cleaned the bore. Shot a few more rounds with another cleaning and then shot Hornady 77 grain bthp match rounds. I could tell the groups tightened up using the heavier round. I had read others reviews about how this barrel seems to like the heavier rounds. I really think this barrel is going to be a keeper!


  3. Excellent barrel for the price 5 Star Review

    Posted by on 2nd Aug 2017

    Bought this barrel to replace a 24" DPMS HBAR and couldn't be happier with how the rifle turned out. Barrel shot into 1 MOA off a bipod and no rear rest with a loaner, budget scope. I have no doubt it will do even better with a better scope and optimized load developed (I used 55gr FMJBT under 25gr H335: bulk reloads). Totally unexpected for the price paid and ran flawlessly. If you're considering the GM-M20, go ahead and buy with confidence.


  4. GM-M20 to replace old 18" barrel 5 Star Review

    Posted by on 5th Jun 2017

    Just wanted to let you know that my 20" Wylde barrel that was ordered and shipped to my gunsmith, American Pride, was a great buy. It replaced an 18" Wylde barrel that wasn't doing the job and after talking to my gunsmith about a replacement he brought up your company on the computer and I made the purchase with the barrel going to him. I just got back my AR-15 on Wednesday and then yesterday I went out to break in the barrel according to the instructions that I received from you last week. I did 100 rounds and zeroed in my scope for 100 yards and was very satisfied with the results and I was shooting faster than usual and then stopping to do the cleaning per your instructions and even then I was very happy. I can't wait to get back out to the shooting range and this time not have to worry about break in and just do some shooting. To let you know you have a happy customer down south.


  5. It's very rare I give a 5 star review. 5 Star Review

    Posted by on 1st Mar 2017

    And the only reason I wont here is that I have only run about 100 rounds through it.

    I shopped for quite a while before deciding on this barrel and am certainly not dissatisfied with my purchase. I knew it would be a shooter when first time out, just to get a few rounds down it, it held MOA at 100 yards with one particular group of 5. I load my own ammo and returned to the range with multiple 5 shot test groups built on 68 Hornady BTHP, 69 SMK and Nosler 77 BTHP. With the right powder this barrel held sub-MOA with all three bullet choices. The furthest spread in the keeper groups was .917" and this was off a bag not a sled. Also, these tests were .5 grain increments at book OAL so I expect the best is still to come.
    I'll also throw in that I built a lefty and the barrel extension works flawlessly with my RRA BCG.
    Great Barrel, Great Service. I would definitely recommend it.
