Faxon Firearms Match Series 16" Gunner Barrel 5.56 NATO - Duty ML Nitride

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.

Frequently Asked Questions

Will this barrel work on my AR-15 upper receiver?

Yes. This is a standard 5.56 NATO barrel with a mid-length gas system and 1/2-28 muzzle thread, compatible with any AR-15 upper assembly. Make sure your upper is chambered for 5.56 NATO or .223 Remington.

What's the difference between the Gunner profile and other barrel profiles?

The Gunner profile combines the ruggedness of a Government profile with the weight savings and quicker handling of a Pencil profile. It's lighter and faster than a full Gov't barrel but more durable than a Pencil, and it shifts the balance point closer to your body to reduce shooting fatigue during long sessions.

Can I use a suppressor on this barrel?

Yes. The 1/2-28 muzzle thread is the standard pattern for most 5.56 suppressors and muzzle devices. Your suppressor must be rated for 5.56 NATO.

Is this barrel suitable for hunting?

Yes. The 16" length and 1:8 twist provide reliable performance for hunting applications. The target-crowned bore and individual headspace inspection support the accuracy needed for ethical, effective hunting.
