Product Description

Upgrade or complete your build with the FN AR-15 premium 14.7-inch 5.56x45mm NATO barrel, engineered for durability, consistency, and long service life. 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.
