Each barrel is magnetic particle tested for consistency and quality, then finished with a corrosion-resistant matte black manganese phosphate. A chrome-lined bore and chamber help resist corrosion and heat erosion for long barrel life and reliable chambering and extraction, while the M4-style feed ramps and barrel extension promote consistent feeding.\u003c\/p\u003e\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e16-inch M4 profile AR-15 barrel chambered in 5.56x45mm NATO\u003c\/li\u003e\n  \u003cli\u003eCold hammer forged construction using Chrome Moly Vanadium steel for durability\u003c\/li\u003e\n  \u003cli\u003eChrome-lined bore and chamber for corrosion resistance and improved barrel life\u003c\/li\u003e\n  \u003cli\u003eCarbine-length gas system design with M4 feed ramps for reliable cycling and 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\u003eBrand: FN\u003c\/li\u003e\n  \u003cli\u003eModel \/ Firearm Fit: AR-15\u003c\/li\u003e\n  \u003cli\u003eCaliber: 5.56x45mm NATO\u003c\/li\u003e\n  \u003cli\u003eBarrel Length: 16 in\u003c\/li\u003e\n  \u003cli\u003eProfile: M4\u003c\/li\u003e\n  \u003cli\u003eGas System Length: Carbine\u003c\/li\u003e\n  \u003cli\u003eConstruction: Cold Hammer Forged (CHF)\u003c\/li\u003e\n  \u003cli\u003eMaterial: Chrome Moly Vanadium Steel\u003c\/li\u003e\n  \u003cli\u003eBore\/Chamber: Chrome lined\u003c\/li\u003e\n  \u003cli\u003eFeed Ramps: M4-style feed ramps and barrel extension\u003c\/li\u003e\n  \u003cli\u003eFinish: Manganese phosphate \/ black phosphate (matte black)\u003c\/li\u003e\n  \u003cli\u003eMuzzle: Threaded\u003c\/li\u003e\n  \u003cli\u003eTwist Rate: 1:7\u003c\/li\u003e\n  \u003cli\u003eTesting: Magnetic Particle tested\u003c\/li\u003e\n  \u003cli\u003eWeight: 2.02 lb\u003c\/li\u003e\n  \u003cli\u003eUPC: 845737008376\u003c\/li\u003e\n  \u003cli\u003eManufacturer Part Number: 20100047\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.
