FN 5.56 AR-15 Barrels

FN AR-15 premium barrels undergo meticulous manufacturing processes using domestically sourced Chrome Moly Vanadium material according to Mil-B-11595E specifications. Each barrel is subjected to High Pressure Testing (HPT) and Magnetic Particle Inspection (MPI) to detect and eliminate any potential micro-stresses or flaws. To enhance durability and reliability, both the bore and chamber of the barrels are chrome lined. The inclusion of M4 style feed ramps and barrel extension guarantees consistent feeding, while the matte black Manganese Phosphate finish offers resistance to external corrosion and oxidation.
