  1. Way Over Gassed 2 Star Review

    Posted by on 8th Apr 2017

    This barrel is over gassed at .85 - .87 gas port
    Need I say more. BCG keeps outrunning the magazine and Causes jams . Hopefully H3 buffer with extra power buffer spring will fix it.

  2. Best barrel yet 5 Star Review

    Posted by on 2nd Feb 2017

    I built a 10.5" SBR with this barrel and could not be any happier. Tolerances were very tight, which makes everything easier to build. Night and day difference to the Bear Creek Arsenal barrel on my last build.

  3. Nearly as good as my BCM BFH 16" 5 Star Review

    Posted by on 13th Dec 2016

    I built an AR pistol using a less expensive 10.5" PSA barrel and was disappointed with its accuracy at 36 yards. The groups were more like a shotgun pattern. This Green Mountain 10.5" barrel groups almost as well as my 16" BCM BFH cold hammer forged barrel at 36 yards using various types of 55, 62 75 and 77 grain bullets in 223 and 556 NATO loadings. Very pleased with the Green Mountain barrel so far. Also, the customer support was great.

  4. Best 5.56 SBR/Pistol barrel available 5 Star Review

    Posted by on 21st Nov 2016

    I keep coming back for quality every time I want a great build. Every detail is spot on with Green Mountain barrels. I've built using this 10.5" barrel twice now along with their 16" barrels many times before and they all function flawlessly. They shoot great groups right out of the box and get better as they foul in a little. Can't beat these considering they're chrome lined and a heavy profile to boot. If you're looking for a great chrome lined barrel your search is over!

  5. Great Barrel for a Pistol Build 5 Star Review

    Posted by on 15th Nov 2016

    Great Looking Quality Just Like all of the Green Mountain Barrel I have Purchased, Another Great Point to Note about these Barrels is inclusion of a extractor support pin, this also is on some of their 14.5" Barrels, Good Option. Love Green Mountain Quality, Good Value
