The Faxon 10.5″ 5.56 NATO SOCOM Barrel w/ Pinned Gas Block is a high-performance option designed to meet the demands of duty and defense builds. Machined from 4150 Chrome Moly Vanadium (CMV) steel and treated with a QPQ Nitride finish, this barrel delivers enhanced surface hardness, corrosion resistance, and long-lasting durability. Featuring an M4 feed ramp extension, it is fully manufactured in-house from quality bar-stock and is individually checked for headspace using precision custom hardened gauges.

This 10.5″ barrel features a Carbine-length gas system and includes a low-profile pinned gas block.
