FN
M16 20” 5.56 Barrel
FN AR-15 premium button-rifled barrels are crafted from U.S.-sourced Chrome Molybdenum Vanadium steel, compliant with Mil-B-11595E specifications. Each barrel undergoes High Pressure Testing (HPT) and Magnetic Particle Inspection (MPI) to detect any micro-stresses or flaws, ensuring superior consistency and quality with every barrel shipped. The bore and chamber are chrome-lined for enhanced corrosion resistance and improved heat erosion resistance, significantly extending barrel life and ensuring reliable chambering and extraction. Featuring M4-style feed ramps and barrel extension, the design ensures consistent feeding, while the matte black Manganese Phosphate finish provides added protection against external corrosion and oxidation.
