The Faxon 5.56 NATO 14.5″ SOCOM Barrel is engineered for strength, reliability, and performance under demanding conditions. Crafted from 4150 Chrome Moly Vanadium (CMV) steel, this barrel receives a QPQ Nitride treatment for superior corrosion resistance and surface hardness. With an M4 feed ramp extension and match-grade machining, it ensures smooth feeding and long-term durability, even in high-volume shooting environments.

This 14.5″ SOCOM Barrel is 100% manufactured in-house by Faxon from certified gun-barrel-quality bar stock. Every unit undergoes a battery of quality control measures, including individual headspace verification using precision custom hardened gauges. The result is a barrel that is as rugged as it is accurate—trusted by civilian builders and professional operators alike.

Configured with a mid-length gas system, this barrel provides a smoother recoil impulse compared to carbine-length systems, increasing reliability and shooter comfort. It also features a 0.75″ gas block journal for compatibility with a wide range of low-profile gas blocks. The 14.5″ length makes it an ideal candidate for a permanently attached muzzle device to reach the legal 16″ minimum overall barrel length, creating a compact yet compliant rifle setup.

What defines the SOCOM profile?

The SOCOM profile is a robust military-style contour originally designed for use by U.S. Special Operations Command. It provides excellent heat distribution and resistance to barrel whip during sustained fire. The heavier profile forward of the gas block enhances rigidity and accuracy while maintaining durability under stress. Whether you’re running high round counts or looking for a rugged barrel that won’t let you down, the SOCOM profile delivers.
