Product Description

Upgrade or complete your AR-15 build with this FN 16-inch 5.56x45mm NATO barrel, built 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, ease of extraction, and long-term barrel life, while M4-style feed ramps and barrel extension promote smooth, reliable feeding. Finished in a matte black manganese phosphate coating for external corrosion resistance, this M4-profile barrel is designed for dependable performance with a carbine-length gas system.
