Product Description
The Faxon Firearms Duty Series Pencil Profile 16″ .308 Winchester AR10 barrel is engineered for shooters who want an exceptionally lightweight large-frame build without sacrificing practical accuracy and durability. Built from 4150 CMV/Mil-Spec steel and finished with salt bath nitride (QPQ) inside and out, this barrel is designed to resist corrosion and wear through hard use. A 1:10 twist helps stabilize a wide range of common .308 Win loads, while the mid-length gas system is tuned for smooth cycling on compact 16-inch builds. Manufactured in-house in Cincinnati, Ohio, each barrel is stress relieved, air-gauge tested, and finished with an 11° target crown to support consistent performance.
