Details

The Faxon Firearms Duty Series 16" barrel is a reliable upgrade for AR-15 rifles chambered in 5.56 NATO. It’s made from strong 4150 CMV steel with a chrome-lined interior to help resist wear and carbon buildup. The outside is coated with a phosphate finish for added durability, while the M4 profile and carbine-length gas system make it compatible with many standard AR builds. This barrel features a .750" gas block journal, 1/2x28 threaded muzzle, and a precisely cut 11-degree crown for improved accuracy. Made in the USA.
