Product Description

The FN AR-15 premium barrel is built for dependable performance in compact 5.56x45mm NATO builds, combining a 10.5 inch M16 profile with a carbine-length gas system for reliable cycling. Manufactured from U.S.-sourced chrome moly vanadium steel to Mil-B-11595E, each barrel is High Pressure Tested (HPT) and Magnetic Particle Inspected (MPI) to help ensure consistent quality. A chrome-lined bore and chamber improve corrosion resistance and reduce heat erosion for extended barrel life, while M4 style feed ramps and a durable matte black phosphate finish support smooth feeding and long-term durability.
