Manufactured from U.S.-sourced Chrome Moly Vanadium steel in accordance with Mil-B-11595E standards, this M16-profile barrel features a carbine-length gas system and a 1:7 twist rate optimized for stabilizing a wide range of 5.56 projectiles. The bore and chamber are chrome lined to resist corrosion and heat erosion, greatly extending barrel life and ensuring consistent chambering and extraction. M4-style feed ramps paired with a precision barrel extension promote smooth, reliable feeding, while the matte black Manganese Phosphate finish protects the exterior against oxidation and corrosion. Before leaving the factory, every barrel is subjected to High Pressure Testing (HPT) and Magnetic Particle Inspection (MPI) to confirm it is free from microstresses or defects, guaranteeing the consistency and quality FN is known for worldwide.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary-Grade Chrome Moly Vanadium Construction:\u003c\/strong\u003e Manufactured from U.S.-sourced material per Mil-B-11595E for superior strength, toughness, and long-term reliability.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChrome Lined Bore and Chamber:\u003c\/strong\u003e Exceptional resistance to corrosion and heat erosion significantly extends barrel life and promotes reliable extraction in all conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh Pressure Tested (HPT) and Magnetic Particle Inspected (MPI):\u003c\/strong\u003e Every barrel is individually tested and inspected to guarantee it is free from microstresses or structural flaws.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eM4-Style Feed Ramps and Barrel Extension:\u003c\/strong\u003e Ensures consistent, reliable feeding across a wide variety of 5.56x45mm NATO ammunition types.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManganese Phosphate Matte Black Finish:\u003c\/strong\u003e Corrosion- and oxidation-resistant exterior finish keeps the barrel protected under demanding field conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\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\u003eCaliber:\u003c\/strong\u003e 5.56x45mm NATO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 16\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProfile:\u003c\/strong\u003e M16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRifling Method:\u003c\/strong\u003e Button Rifled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System:\u003c\/strong\u003e Carbine Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Black Phosphate (Manganese Phosphate)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore\/Chamber Lining:\u003c\/strong\u003e Chrome Lined\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Chrome Moly Vanadium (Mil-B-11595E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeed Ramps:\u003c\/strong\u003e M4 Style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle:\u003c\/strong\u003e Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTesting:\u003c\/strong\u003e High Pressure Tested (HPT) and Magnetic Particle Inspected (MPI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 20100039\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 845737008505\u003c\/li\u003e\n\u003c\/ul\u003e\n\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.
