Description

Manufactured in-house, these barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.

From there, each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace by precision custom hardened gauges.

    My second time getting one of these, and they always impress with their light weight and consistent accuracy.

    I have not shot this barrel yet but have 3 other Faxon Pencil barrels and they all shoot excellent, I love these barrels as they are light weight and still shoot well.

    16" pencil-profile barrel, cal. 5.56x45

    Posted by David Burch on May 4th 2022

    Fit and finish are top-notch, as expected from Faxon. Initial testing with 55-grain FMJ handloads yielded accuracy as good as the Gunner-profile barrels on my other AR rifles. But this barrel is a bit lighter, and when combined with a minimalist stock and short free-float handguard, the resulting weapon is quick to the shoulder, balances nicely, and points naturally.

    We bought two

    We liked this barrel so much, we bought a second one as a backup to the one my Mrs installed on her AR-15. We have been getting great groups! Highly recommend.

    Good quality, but overgassed

    Posted by Frank Holub on Jan 12th 2018

    I'm overall satisfied with my Faxon pencil barrel, but the one issue I have with it is that it's severely overgassed, causing significant bolt bounce during cycling. The issue was fixed with an adjustable gas block, but it shouldn't really be an issue in the first place with the common .223 and 5.56 loads I was using. Other than that, the barrel is made of quality materials, the finish is impeccable, and accuracy is good too, though anyone buying a pencil barrel should be aware it heats up fast, opening groupings up a bit once hot.
