Faxon Duty Series 10.5″ Light Tapered 10mm 4150 Nitride Barrel
The Faxon Duty Series 10.5″ Light Tapered 10mm 4150 Nitride Barrel is a purpose-built option for shooters looking to harness the power of 10mm Auto in an AR-style platform. Engineered with performance and durability in mind, this barrel is ideal for pistol-caliber carbine (PCC) builds that require strength, reliability, and a compact form factor. Faxon’s Duty Series barrels are trusted by professionals and enthusiasts alike for their precision machining and battle-proven materials.
This 10.5″ barrel is machined from 4150 chrome moly vanadium steel and finished inside and out with a black QPQ nitride coating. This treatment enhances corrosion resistance and wear life while maintaining a smooth, low-friction surface for consistent cycling. With a 1:16 twist rate, the barrel is tuned for optimal stabilization of 10mm projectiles across a wide range of bullet weights, delivering dependable accuracy with both range and defensive loads. The light tapered profile strikes a balance between weight reduction and strength, making it well-suited for lightweight PCCs without compromising structural integrity.
The muzzle is threaded 5/8×24, allowing for easy installation of muzzle devices or suppressors tailored to 10mm performance. An 11-degree target crown helps ensure repeatable accuracy by reducing gas disruption at the muzzle. This barrel is non-ported and designed for blowback operation, removing the need for a gas system and simplifying the build process.
It features a standard barrel extension and is compatible with dedicated 10mm AR builds that utilize Glock® pattern magazines. At just over 1 pound in weight, it adds minimal bulk while maintaining rugged reliability. Whether you’re building a tactical 10mm PCC or a compact defensive firearm, the Faxon Duty Series 10.5″ 10mm barrel provides the strength and precision needed for high-performance shooting.
