  1. very accurate 5 Star Review

    Posted by on 24th May 2017

    Purchased this for my wife's build last year, after some teething problems with the buffer and spring got it working perfectly, the gun weight's about 6lb with scope and bipod, consistently shoots 1/2 moa @ 100 yards, even thought it is fluted accuracy doesn't change. PS: whish they had one in 6.5 Grendel.


  2. A Great Barrel 5 Star Review

    Posted by on 8th Feb 2017

    I purchase GM barrels and will continue to do so. Great customer service and a quick shipper. Wish they would produce AR308 barrels.


  3. Great local product 5 Star Review

    Posted by on 22nd Jan 2017

    Love this barrel, would recommend to anyone!!


  4. Great Customer Service and Product 4 Star Review

    Posted by on 24th Oct 2016

    The only reason why I'm giving this 4 stars is because I havent had the chance to go to the range and test out the barrel. Received my barrel very quickly and it came packaged very neatly with plenty of protection. Finished by build and everything fit perfectly


  5. Best Lite barrel I have used on a Ultra Lite AR custom build 5 Star Review

    Posted by on 6th Sep 2016

    I have built dozens of custom ARs for many customers. When they want the lightest 16" I use this barrel. They all have shot 5 shots in less than 1 inch at 100 yards with the right ammo.
