Description
The Faxon Gov't/Socom Duty Series is a 10.5-inch AR-15 barrel chambered for 5.56x45mm NATO. It is made from 4150 CMV steel with a black nitride finish and a 1:8 twist rate, and it is designed to fit AR-15 style rifles.
The raw text describes this barrel as a Faxon Gunner profile, a blend of the Gov't and Pencil profiles. It is button rifled and magnetic particle inspected, and the listing states it is intended to reduce weight while allowing long-term suppressor use. A 10.5-inch length is a common pistol-length barrel and should be matched to the receiver and gas system for your build.
