  1. Great Barrel 5 Star Review

    Posted by on 30th Aug 2017

    When I received my barrel it was well packaged and fit and finish is great. I mounted to a matched Spike's upper and lower. With the right ammo it shoots sub MOA at 100 m. Great barrel!!

    Posted by on 25th Aug 2017

    I received my barrel, assembled my gun put a vortex viper on it, shot and hit an 1/8 inch to left of my intended target. Then proceeded to put two more shots through the first shot. Very impressed!

    Nice product. We had to open the gas port hole a tad to allow more gas for our stouter spring but worked like a charm.
    Thanks
