Faxon 16″ 5.56 NATO SOCOM Barrel w/ Pinned Gas Block
The Faxon 16″ 5.56 NATO SOCOM Barrel w/ Pinned Gas Block delivers proven military-grade durability and heat control for demanding shooters. Machined from high-strength 4150 Chrome Moly Vanadium (CMV) steel, this barrel features a corrosion-resistant QPQ Nitride finish and an M4 feed ramp extension to ensure optimal reliability and feeding under any condition. It’s 100% made in-house by Faxon from premium bar-stock and individually headspaced with precision-hardened gauges for long-lasting performance.
Configured with a Mid-Length gas system and SOCOM profile, this barrel offers a heavier contour for superior heat absorption and reduced point-of-impact shift during extended firing sessions. The SOCOM profile is a trusted standard, used by Special Operations Command for its balance of rigidity and sustained fire capability, making it ideal for duty rifles and rigorous training builds alike.
This model includes a pre-notched gas block journal paired with a factory-installed, pinned low-profile gas block for extra peace of mind. The secure fitment eliminates gas block movement and enhances overall system reliability—even during high-volume or suppressed shooting sessions.
