16" Pencil, 5.56 NATO, Mid-Length, 4150 QPQ
Our pencil barrels are the lightest in the industry. Don't take just our word for it, major companies like Robar, Kaiser US, 2A Armament, and others choose Faxon pencils for their ideal balance of weight and performance.
Faxon Firearms barrels are the pinnacle of value. Manufactured 100% in-house from cradle-to-grave, 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.

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.
Nice fit and finish, fairly light.
Very elegant and cleanly machined. The high gloss finish is also a nice touch.
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.
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.
This is hands down the best light weight barrel on the market. Buy it...you won't be sorry you did.
Purchased the pencil barrel a few weeks ago building a lightweight coyote night rig. Wanted it light because the night scope weighs 3 lbs. The rifle came out under 10 lbs with the scope.Used Hornady factory ammo 55gr vmax. Sighted it in at 100. entered the ballistic data in the scope. walked a self healing target out to a random distance. Hit the target with the range finder at 258 yards. set the range in the scope shot 3 rounds in a tad under an inch.
I have much heavier barrels that can't do this.
Put this barrel on a skinny AR15 build, added a mlok MI G3 rail and it's insanely light up front. Shot great right out of the box.
Have used a lot of Faxon barrels especially there PENCIL PROFILE BARREL, which meet or exceeds all expectation for accuracy and quality will continue to build on all FAXON barrels
