    Great Barrel

    Posted by Robert McDermott on Jul 30th 2025

    This is my 7th Faxon barrel. Like the others, this barrel is beyond excellent! I haven’t shot it yet, but the accuracy of my other Faxon barrels has been impressive.

    Great barrel

    Posted by William Krajeski on Feb 6th 2024

    I bought a couple of these 762 X 39 and 556 never had an issue. Great barrels, my buddies bought from other manufacturers before and almost always has feed ramp or clearance issues, I've never had one with any of the facts and barrels I've bought highly recommend.

    7.62x39mm 16" barrel

    Posted by David B on Oct 6th 2023

    This barrel is the key component in the most accurate semiautomatic rifle I have ever owned. It delivers consistent small groups with handloads using the Hornady 150-grain BTSP. This upper on a lower equipped with a Timney trigger is now my go-to deer rifle for northern Wisconsin.

    Fine stuff

    Posted by Stephen Crump on Sep 11th 2023

    With a little heavier buffer (not Faxon issue) my Adams Arms gas piston system has my AR eating everything including Russian Steel. Faxon is a great place to get your build going.

    I purchased both this and the 5R limited edition and they both shoot wonderfully. Faxon is great for well made products at a more affordable price. We appreciate that Faxon!
