  1. excellent barrel 5 Star Review

    Posted by on 2nd Sep 2020

    I wanted this to be single shot so I didn't drill a gas port and left it full profile.
    Very tight chamber and minimal neck expansion....the press handle just drops thru when full length sizing.
    Excellent accuracy!! Can't say enough good about this barrel!

  2. Excellent product! 5 Star Review

    This was my first 300 Blackout build So I wasn't sure what to expect. The barrel produced 2 inch groups with commercial ammo and 1 inch groups with my handloads. I'm very happy with the quality of the barrel and will definitely be buying more.

  3. Great buy! 5 Star Review

    I am very pleased with this barrel, did some minor finish work, didn't even bother to cut it, installed it on my M&P15, it worked flawlessly. I'm very pleased with the accuracy I've been able to achieve so far, and I expect it to get better as the barrel gets broke in.
