Faxon Duty Series 5.56 NATO 12.5" CMV Barrel Chrome Mag Phosphate 1/2-28

Product Description

The Faxon Firearms Duty Series 5.50" barrel is built for shooters who demand reliable performance in the most demanding environments. Crafted from 4150 Chrome Moly Vanadium (CMV) steel, this barrel offers outstanding strength, toughness, and longevity compared to standard barrel steels.

The Black Chrome Mag Phosphate finish provides a rugged layer of corrosion and wear resistance, making it well-suited for hard-use duty and defensive applications. Button rifled with a 1:7" twist rate, the barrel reliably stabilizes a broad spectrum of 5.56 NATO projectile weights.

A 1/2"x28 threaded muzzle allows easy installation of suppressors, flash hiders, and other popular muzzle devices, while the .750" gas block journal accommodates standard low-profile gas blocks for a clean and lightweight AR-15 build.
