Overview
The Faxon Duty Series AR-15 barrel combines a 12.5-inch length and 5.56x45mm NATO chambering with Faxon's proprietary Gunner profile, blending Government-weight rigidity behind the gas block with Pencil-weight maneuverability forward for reduced fatigue and faster handling. Manufactured from 4150 CMV steel, it features a durable salt bath nitride finish inside and out, button-rifled 1:8" twist tracking, a mid-length gas system, and a .625" gas block journal. Built with an M4 barrel extension and an 11-degree target crown, each barrel undergoes magnetic particle inspection (MPI) and air-gauge testing to ensure precise performance and reliability. It is threaded 1/2x28 and compatible with standard AR-15 upper receivers.
