  1. 11.5" finned barrel 5 Star Review

    Posted by on 15th Sep 2022

    This barrel is well made and looks kick-ass. I put it on a LE sample SBR with select fire capabilities and seems to run great.


  2. Awesome made barrel 5 Star Review

    The Craftsmanship that went in to this barrel is by far some of the best I've seen. Will take it to the range in a couple days. Thanks for the fast and friendly service.


  3. Great quality 5 Star Review

    The finned barrel was well made. I also purchased the 16” version a few years ago. I am am very satisfied with both and would recommend your products to all my friends.


  4. 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.


  5. 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.
