Product Description

The FN AR-15 Hammer Forged Barrel is built for demanding use with FN’s proprietary high-grade Chrome Moly Vanadium (CMV) steel and a cold hammer forged construction inspired by FN machine gun barrel manufacturing. Each barrel is Magnetic Particle tested for quality control, then finished with a corrosion-resistant phosphate coating. A chrome-lined bore and chamber help resist corrosion and heat erosion for longer service life and more reliable chambering and extraction. Designed for a carbine-length gas system, it also features an M4-style feed ramp and barrel extension to promote consistent feeding in AR-15 pattern rifles.
