Manufactured from U.S.-sourced Chrome Moly Vanadium steel to Mil-B-11595E requirements, this button-rifled 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 help resist corrosion and heat erosion for improved barrel life and reliable chambering\/extraction. The M4-style feed ramps and barrel extension support consistent feeding, while the matte black manganese phosphate \/ black phosphate finish helps resist external corrosion and oxidation. Built around a mid-length gas system and an M16-style profile, it’s a strong choice for hard-use AR-15 configurations.\u003c\/p\u003e\n\n\u003ch3\u003eProduct Highlights\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFN premium AR-15 barrel in 5.56x45mm NATO with a compact 14.7-inch length for versatile builds\u003c\/li\u003e\n  \u003cli\u003eChrome-lined bore and chamber to improve corrosion resistance, heat erosion resistance, and service life\u003c\/li\u003e\n  \u003cli\u003eHPT and MPI tested for added confidence in consistency and quality\u003c\/li\u003e\n  \u003cli\u003eM4 feed ramps and barrel extension designed to promote reliable, consistent feeding\u003c\/li\u003e\n  \u003cli\u003eMid-length gas system with durable phosphate finish for long-term corrosion protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eBrand: FN\u003c\/li\u003e\n  \u003cli\u003eManufacturer Part Number: 20100038\u003c\/li\u003e\n  \u003cli\u003eOther Marking\/Item Number: 20-100038\u003c\/li\u003e\n  \u003cli\u003eUPC: 845737008451\u003c\/li\u003e\n  \u003cli\u003ePlatform: AR-15\u003c\/li\u003e\n  \u003cli\u003eCaliber: 5.56x45mm NATO (also commonly used with .223 Remington)\u003c\/li\u003e\n  \u003cli\u003eBarrel Length: 14.7 in\u003c\/li\u003e\n  \u003cli\u003eProfile: M16 \/ Government-style profile\u003c\/li\u003e\n  \u003cli\u003eGas System Length: Mid-length\u003c\/li\u003e\n  \u003cli\u003eMaterial: Chrome Moly Vanadium (CMV) steel (Mil-B-11595E)\u003c\/li\u003e\n  \u003cli\u003eBore\/Chamber: Chrome lined\u003c\/li\u003e\n  \u003cli\u003eRifling Method: Button rifled\u003c\/li\u003e\n  \u003cli\u003eFeed Ramps: M4\u003c\/li\u003e\n  \u003cli\u003eGas Block Journal Diameter: 0.750 in\u003c\/li\u003e\n  \u003cli\u003eMuzzle Threads: 1\/2x28\u003c\/li\u003e\n  \u003cli\u003eFinish\/Color: Black phosphate \/ manganese phosphate (matte black)\u003c\/li\u003e\n  \u003cli\u003eTesting: High Pressure Tested (HPT) and Magnetic Particle Inspected (MPI)\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.
