Manufactured from U.S.-sourced Chrome Moly Vanadium steel (per Mil-B-11595E), each barrel is High Pressure Tested (HPT) and Magnetic Particle Inspected (MPI) to help ensure it is free of microstresses or flaws. A chrome-lined bore and chamber improve corrosion resistance and help reduce heat erosion for extended barrel life and consistent chambering\/extraction. M4-style feed ramps and a matching barrel extension promote dependable feeding, while a matte black manganese phosphate finish helps resist external corrosion and oxidation.\u003c\/p\u003e\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003ePremium FN AR-15 barrel with M4-profile design for carbine-style builds\u003c\/li\u003e\n  \u003cli\u003eChrome-lined bore and chamber for corrosion resistance and improved barrel longevity\u003c\/li\u003e\n  \u003cli\u003eHPT and MPI inspected to support consistent quality and reliability\u003c\/li\u003e\n  \u003cli\u003eM4 feed ramps and barrel extension for smooth, consistent feeding\u003c\/li\u003e\n  \u003cli\u003eMatte black manganese phosphate finish helps resist external corrosion and oxidation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e FN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 20100044\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 845737008567\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform\/Fit:\u003c\/strong\u003e AR-15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 5.56x45mm NATO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 14.70 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRifling:\u003c\/strong\u003e Button rifled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProfile:\u003c\/strong\u003e M4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System Length:\u003c\/strong\u003e Carbine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Chrome Moly Vanadium steel (Mil-B-11595E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore\/Chamber:\u003c\/strong\u003e Chrome lined\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeed Ramps:\u003c\/strong\u003e M4 style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Color:\u003c\/strong\u003e Matte black manganese phosphate \/ black phosphate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
