Product DescriptionThe 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 11Adeg target crown to support consistent performance.Product Highlights Ultra-light Pencil contour reduces rifle weight for faster handling and easier carry Salt Bath Nitride (QPQ) finish inside and out for enhanced corrosion and wear resistance 1:10 twist rate for broad .308 Winchester load stabilization Mid-length gas system for balanced cycling and recoil impulse on 16" AR10 builds 11Adeg target crown and air-gauge testing to support consistent accuracySpecs Brand: Faxon Firearms Series: Duty Series Platform Compatibility: AR10; DPMS / LR-308 compatible Caliber: .308 Winchester (SAAMI) Barrel Length: 16" Profile: Pencil Twist Rate: 1:10 Rifling: Button rifled Material: 4150 CMV / Mil-Spec steel Finish: Salt Bath Nitride (QPQ), inside & out Gas System: Mid-length Gas Block Diameter: 0.750" Gas Block Journal Length: 1.1" Muzzle Threads: 5/8x24 TPI Crown: 11Adeg target crown (non-recessed) Weight: 1.83 lb Country of Manufacture: USA (Cincinnati, Ohio) UPC: 816341023277 Manufacturer Part Number: 10A810M16NPQDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
