Faxon Firearms Duty Series 9mm Luger 8.5" 1:10 Twist Light Taper AR-15 Barrel - Black Nitride

The Faxon Firearms Duty Series 8.5" 9mm barrel is purpose-built for AR-15 pistol-caliber carbine (PCC) builds, chambered in 9mm Luger (9mm SAAMI) and finished in a durable Black Nitride coating. Cut from 4150 chrome moly vanadium steel with a light taper profile designed specifically for the pistol-caliber platform, it threads into a standard AR-15 upper and delivers an ideal balance of weight savings and rigidity for compact 9mm PCCs.

This 8.5-inch barrel carries a 1:10 twist rate for reliable stabilization across common 9mm bullet weights and is machined with feed ramps compatible with both Glock-pattern and Colt-pattern magazines. It is designed for the straight-blowback operating system standard to 9mm AR-15 builds, with 1/2x28 thread pitch to accept standard 9mm muzzle devices and a recessed 11-degree target crown for dependable accuracy.

At roughly 0.81 lbs, this is one of the lightest 9mm barrels in the Faxon lineup, making it an excellent choice for a balanced, fast-handling pistol-caliber AR. The overall length is approximately 9.3". Constructed from certified Mil-Spec 4150 CMV steel and finished with a black nitride treatment for long-lasting corrosion resistance, a hardened bore surface, and a low-friction shooting experience.

Whether you are piecing together a new 9mm AR-15 pistol build, a compact PCC carbine, or refreshing an existing 9mm upper, the Faxon Duty Series 8.5" Light Taper 9mm barrel is a precision-rifled blank ready to drop into your next project.
