Faxon 5.56 NATO 16″ Pencil Barrel

Modeled after the Colt SP1, an ideal balance of weight and performance.

The Faxon 5.56 NATO 16″ Pencil Barrel is designed to deliver unmatched weight savings without compromising accuracy or reliability. Crafted from 4150 Chrome Moly Vanadium (CMV) steel, this barrel features a QPQ Nitride finish for increased corrosion resistance, surface hardness, and overall longevity. The Nickel Teflon-coated M4 feed ramp extension ensures smooth, consistent feeding even in high-volume shooting sessions.

Every Faxon barrel is 100% manufactured in-house using gun-barrel-quality bar stock and goes through rigorous inspection protocols. Faxon performs a full battery of quality assurance tests on each barrel, including magnetic particle inspection (MPI) and custom hardened gauge headspace checks, ensuring your barrel performs flawlessly right out of the box.

The 16″ length combined with a Mid-Length gas system offers enhanced reliability and reduced recoil impulse, making this barrel an excellent choice for lightweight builds, competition rifles, or general-purpose carbines. The 0.625″ gas block journal allows compatibility with a wide range of low-profile gas blocks, keeping your build streamlined and minimal.

Faxon’s Pencil profile barrels are some of the lightest in the industry, modeled after the legendary Colt SP1 design. Major firearm innovators like Robar, Kaiser US, and 2A Armament rely on Faxon’s Pencil barrels for builds that demand both extreme weight reduction and consistent accuracy.

If you’re seeking a premium-grade barrel that reduces front-end weight and enhances maneuverability while retaining rugged reliability and precision, the Faxon 5.56 NATO 16″ Pencil Barrel is an outstanding upgrade for your AR platform.
