  1. Another great GM Barrel 5 Star Review

    Posted by on 18th Jun 2018

    :Like previous GM Barrels I've purchased the 10.5" 5.56 barrel is great. Fit and finish is top shelf. For a 10.5" barrel for a AR Pistol on it's first time out to the range I was getting 2.5" groups @100yds off hand, off a rest (bag) groups were under 1.5" using Hornady .223 Superperformance 55gr VMax varmint loads.
    I was a little concerned about the over gassed review, shells are ejecting @ 3 o'clock.

  2. Great Barrel at a Great Price! 5 Star Review

    Posted by on 21st May 2018

    I ordered the 10.5" barrel for an AR Pistol i was putting together, and it easily met, even exceeded my expectations. The gas port does seem to be a little over-sized, but that's nothing an adjustable gas block and/or heavier buffer/buffer spring can't fix (which I was planning to do anyway). The finish looks top notch both inside and out. The accuracy seems very good, but I've only shot out to 50 yards so far (and only ~200 rounds). Finally, the shipping time was outstanding: ordered the barrel on a Monday (4/30), and it was delivered via UPS on Wednesday (5/2). This was my first Green Mountain purchase, but it certainly will not be my last!

  3. 10.5 chrome lined barrel 5 Star Review

    Posted by on 12th Apr 2018

    Barrel works great for my pistol build

  4. 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.

  5. 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.
