Availability: In Stock
The Faxon Firearms Match Series 16" Gunner Barrel in 5.56 NATO is a purpose-built component for shooters who want accuracy without sacrificing shooter comfort during extended range sessions, training, or field work. Faxon's Gunner profile splits the difference between two proven designs—the durability of a Government profile and the handling speed of a Pencil profile—to deliver a balanced AR upper that won't wear you out. The result is a barrel that brings the rifle's mass closer to your body, reducing fatigue when you're logging hours behind the gun, whether you're zeroing a new build, running drills, or hunting.
Built in-house in Cincinnati, Ohio, this Match Series barrel starts with certified 4150 CMV steel and undergoes a rigorous QA pipeline before it ever ships. Every barrel is stress-relieved, air-gauge tested, crowned to 11 degrees for precision, and individually headspace-checked with PTG gauges. The button-rifled bore features a 1:8 twist optimized for the 5.56 NATO cartridge, and the entire barrel—inside and out—is finished in Nitride, a hard, corrosion-resistant coating that handles the abuse of training and field use.
The 1/2-28 muzzle thread accepts standard AR accessories and suppressors. At 16 inches, this barrel hits the sweet spot for velocity, handling, and utility—short enough to maneuver in tight spaces but long enough to wring most of the energy from your ammunition. Whether you're building a duty rifle, a training platform, or a hunting upper, the Faxon Gunner gives you factory-tested reliability and repeatability without the inflated price tag of boutique brands.
