The Faxon 5.56 NATO 7.5″ SOCOM Barrel is a compact, heavy-duty performer crafted to excel in short-barreled rifle (SBR) and pistol builds. Engineered from 4150 Chrome Moly Vanadium (CMV) steel, this barrel is finished in a QPQ Nitride coating for superior resistance against corrosion, wear, and heat. The addition of an M4 feed ramp extension enhances feeding reliability across various types of ammunition, making it a dependable option for duty use or personal defense setups.

Every Faxon barrel is manufactured 100% in-house from premium bar-stock and is put through a rigorous quality control process. This includes a full battery of inspections such as magnetic particle inspection (MPI) and headspace verification using precision custom hardened gauges. The result is a barrel built to withstand high round counts and extreme operating environments.

The 7.5″ length is ideal for ultra-compact AR builds where maneuverability and weight reduction are top priorities. Configured with a Pistol-length gas system and a 0.75″ gas block journal, the Faxon 5.56 NATO 7.5″ SOCOM Barrel is optimized for reliable cycling and pressure regulation in a short gas system. Despite its size, the SOCOM profile provides enhanced rigidity and superior heat resistance for demanding conditions.

Just what is the SOCOM profile?

The SOCOM profile is a robust military-grade design known for its rigid taper and exceptional heat distribution. Developed for and used by Special Operations units, it offers a balance of durability and thermal stability under sustained fire. Its extra material at key stress points helps minimize barrel whip and maintain accuracy—even under the harshest firing conditions. This makes the SOCOM profile ideal for shooters who demand reliability and performance in a compact format.
