Faxon Ar15 Barrel 5.56 Nato - 12.5" 1:8 Gunner Profile Blk

The Faxon AR15 Barrel 5.56 NATO in 12.5" length with 1:8 twist rate is purpose-built for operators who demand precision in compact platforms. Whether you're configuring a professional duty weapon, a home defense AR, or a precision rifle for tactical training, this Gunner Profile barrel delivers the ballistic performance and reliability that law enforcement and military users depend on. The 12.5" length provides optimal velocity retention while maintaining the handling characteristics essential for close-quarters work and rapid target transitions.

Faxon Firearms' Gunner Profile geometry represents a proven balance between structural rigidity and weight management—critical factors in high-round-count training and extended operational deployments. The 1:8 twist rate stabilizes modern 5.56 NATO ammunition across a broad range of bullet weights, from 55-grain military loads to heavier 77-grain match rounds, ensuring consistent accuracy regardless of load selection. The chrome-lined chamber and bore provide superior corrosion resistance and durability, essential characteristics for weapons exposed to environmental stress or deployed in variable conditions. At 1.25 lbs, this barrel maintains a lightweight profile without sacrificing the structural integrity required for reliable function and precision.

This barrel excels in short-barrel rifle (SBR) builds, pistol-caliber upper conversions, and compact tactical platforms where length constraints demand performance optimization. Installation requires standard AR15 barrel extension tools and knowledge; compatibility is universal across modern direct-impingement and adjustable-gas-block systems. The black Parkerized finish resists corrosion in humid or salt-air environments while maintaining a low-visibility profile. Professional armorers, law enforcement agencies, and experienced builders consistently choose Faxon barrels for their proven reliability, accuracy, and durability under demanding field conditions.
