  1. Great Barrel when not running a Suppressor 5 Star Review

    Posted by on 7th May 2017

    I bought this barrel because I wanted to build an SBR 11.5 in barrel. The barrel runs perfectly up to 400 yrds. Now shooting with my Suppressor is a different story. I would have failure to feed and and the bolt carrier would not lock back after shooting the last round esp with a 30rd mag. but over all I like this barrel and working on how to fix the problem with my suppressor issue.

  2. Accurate as an eagle, cool as a cucumber. 5 Star Review

    Posted by on 9th Sep 2016

    Test fired my new AR, I couldn't feel any heat from the barrel, shot from about 50 yards at a rubber cube and it hit about every time. I won't know how truly accurate this barrel is until I top it with my Aimpoint but for now, it's just what I needed.
