  1. Awesome value 5 Star Review

    Posted by on 21st Jul 2016

    I've ran about 150 rounds through it so far. The fit and finish is great. Barrel is gassed perfectly. Feed ramps were kind of sharp but that's pretty standard. I put it on an aero upper and lower with aero bcg and an ar stoner enhanced trigger.

    Last week shooting 69 grain Winchester match .223 I grouped three rounds .515" and 77 grain black hills 5.56 grouped .860" at 100 yards. All shots were off a bipod with a rear bag. It has fed every .223 and 5.56 round I've tried without any pressure signs.

    If your looking for a budget SPR type barrel this is it.

  2. sub-moa 5 Star Review

    Posted by on 15th Jul 2016

    Used in a 3-gun build with Aero Precision upper, M16 BCG, and Vortex Strike Eagle optic. Easily sub-moa for 5 shots at 100 yards with 55 grain tipped Varmageddon bullets over 8208. Same POI with 75 grain Hornady HPBT over 8208. Rang a half-size IPSC steel plate at 400 yds 20 times in a row when confirming reticle subtensions. Outshoots my 20" Kriegers for accuracy with highest velocity out of 4 other barrels I tested (all 20"). Unbelievable value. I waited until I had fired over 100 rounds to post a review. I'm delighted. My brother just ordered one and my father is about to order two. Terrific finish with excellent machining of muzzle threads, contour, and chamber. No issues installing this barrel in the upper. Thanks to Green Mountain for a great value. I'll certainly buy many more for my subsequent builds.

  3. Top Quality barrels 4 Star Review

    Posted by on 18th Apr 2016

    I have several BPCR Green Mountain Barrels and it just made sense to stick to the same top quality for the AR-15 I'm building great product very good quality.

  4. Great Value 4 Star Review

    Posted by on 17th Dec 2015

    Great looking barrel at a very good price. I had several failure to feed issues during a short break in period. I shot 3 to 5 rounds and then cleaned the barrel. After doing this several times the feeding issue seems to have gone away. Probably a sharp edge or burr preventing the bolt from going completely into battery at times. I just shot around 20 rounds with no issues.

  5. First time AR barrel buy 4 Star Review

    Posted by on 28th Apr 2015

    In doing the research as to the type of barrel I wanted for my first AR build I settled on this barrel because of the WYLDE chamber versatility and the price. Great looking barrel as well. I like the matte finish can't wait to get it installed. Can only give it 4 stars because I haven't fired it yet.
