Description
The Faxon Duty Series Gunner Profile 16" 8.6 BLK AR10 Barrel is a meticulously engineered component designed for the AR-10 platform. This barrel is crafted from 4150 CMV steel and features a QPQ nitride finish for enhanced hardness and corrosion resistance. With a unique 1:3 twist rate, this barrel is optimized for stabilizing heavy subsonic rounds, making it ideal for suppressed shooting applications. The Gunner profile maintains a balance of strength and weight, ensuring durability without unnecessary bulk.
Designed to accommodate a wide range of ammunition, this barrel is chambered for the 8.6 Blackout cartridge, which was SAAMI-accepted in January 2026. The carbine-length gas system, with a .104" port, provides reliable cycling for both supersonic and subsonic loads. This barrel is perfect for those looking to build a versatile AR-10 rifle capable of handling various shooting scenarios.
