Faxon
$175.00
Manufactured in-house, these barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.
Quality is imbued into our barrels from the start. We start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless. 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.

16" pencil-profile barrel, cal. 5.56x45
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.

Very Light. Very accurate. Very well machined
Great barrel. Well machined. Very light and BODA accui. Awesome

Good quality, but overgassed
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.

Pencil barrel
Nice fit and finish, fairly light.

Pencil 556
Very elegant and cleanly machined. The high gloss finish is also a nice touch.

16" PENCIL, 5.56 NATO, Mid-Length, 4150 QPQ
I have built several "loaner uppers" to send out to gun writers to review our QRB takedown system. One writer planned a grouping test without telling use. I sent him the loaner that had just come back from a tester doing 60 round full auto drum dumps. The barrel still shot sub-MOA! Out of an abused pencil with barrel! Faxon Barrels is my go to choice for barrels.

16" Pencil Barrel
This barrel is lightweight and extremely accurate. I have bought 7 of them so far and will continue to buy this model in the future.
