FAXON Duty Series 5.56mm NATO 7.5in Pistol-Length Barrel (15A58P7NSQ)

The FAXON Duty Series 5.56mm NATO Pistol-Length 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.

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.
