  1. SUB MOA 4 Star Review

    Posted by on 29th Sep 2021

    Very well done barrels. Sub moa with 62 gr green tip NATO and heavier bullets.

  2. Nice shooter, good value 5 Star Review

    Posted by on 17th Jun 2021

    Bought this to replace a 16" pencil profile. Only shot 3 5 rounds so far. At 200 yards I got 2" groups with frontier & Winchester fmj. I highly recommend this barrel.

  3. 18inch fluted barrel with black finish. 4 Star Review

    Posted by on 15th Feb 2021

    Very accurate barrel especially if you consider the price only had it out to the range once so far. Put about 80 rounds of 55 grain lake city through it. It’s capable of 1.25 inch 10 groups with that ammo. Probably get better with higher quality ammo. Was using 18 power scope. Would definitely recommend.

  4. Nice Accurate barrel 5 Star Review

    Posted by on 14th Oct 2020

    I am pleased with this barrel. 18 inch fluted 223 Wylde. After about a dozen or so shots to zero the rifle I was able to put a couple 3 shot groups at 50 yards in at under 1/2 inch (.460, and .385). That equates to Sub 1 inch at 100 yards. It has a good finish and great fit in my build. I will buy from Green Mountain again.

  5. Accurate right out of the box 5 Star Review

    Posted by on 2nd Mar 2020

    Finished my first AR build a couple of months age but because of winter weather was unable to test fire until yesterday 3/2/20. Have not "broken in" the barrel yet but we did send 20 rounds down range. I had 4 shots within 1 1/4" at 100 yard and I figure most of the error was me. Unfortunately my scope loosened up ever so slightly but that put an end to shooting for the day.

    Very pleased with this barrel. My next build will definitely be using a Green Mountain Barrel!

    Now to tighten up my scope and go break in the barrel!
