Faxon Duty Series 16″ Light Tapered 10mm 4150 QPQ Nitride Barrel
The Faxon Duty Series 16″ Light Tapered 10mm 4150 QPQ Nitride Barrel is built for shooters looking to take full advantage of the hard-hitting 10mm Auto cartridge in a dedicated pistol-caliber carbine platform. Designed with both performance and durability in mind, this barrel offers a refined balance of strength, weight savings, and reliability, making it a premium option for 10mm AR builds. Crafted from 4150 chrome moly vanadium steel, the barrel is fully treated with a QPQ nitride finish inside and out. This process hardens the surface, enhances corrosion resistance, and promotes a longer service life, even under extended use.
The 16″ overall length maximizes velocity and energy from the 10mm cartridge, making it well-suited for both defensive applications and recreational shooting. The 1:16 twist rate stabilizes a wide range of 10mm bullet weights with consistent accuracy. Its light tapered profile ensures a well-balanced firearm without excessive front-end weight. The barrel is non-ported and optimized for blowback operation, eliminating the need for a gas system and reducing overall mechanical complexity. This makes it a reliable, straightforward choice for builders who want simplicity and performance in one package.
At the muzzle, the barrel is threaded 5/8×24, allowing compatibility with common suppressors or compensators, and it features an 11-degree target crown for improved precision. The barrel extension is compatible with standard AR-15 bolt carrier groups designed for 10mm, and it pairs easily with Glock®-pattern magazine lowers. Whether you’re assembling a tactical PCC or building a custom range rifle, this Faxon Duty Series barrel brings the ruggedness and accuracy required for a high-performing 10mm carbine.
