The Faxon Firearms 5.56 NATO Gunner AR-15 barrel brings genuine versatility to modern AR builds without forcing you into a single configuration for life. This integral muzzle device barrel splits the difference between two proven profiles—the durability of a Gov't profile and the nimble weight savings of a Pencil design—giving you a balanced, all-day shooter that handles hunting, training, and range time equally well. The 14.5-inch rifled tube with integrated muzzle device legally measures 16 inches overall, so you get the maneuverability of a short barrel while staying compliant. Unlike pinned-and-welded setups that lock you in, Faxon's design lets you swap between a 3-port muzzle brake or slotted flash hider, and you can fully service the gas block and barrel nut whenever you want. That's real freedom to reconfigure your rifle as your mission changes.
Built on a mid-length gas system with a .625-inch block diameter, this barrel shoots 5.56 NATO in a 1:8 twist rate—stable and accurate across the whole ammunition spectrum. The Gunner profile's geometry brings the balance point back toward your shoulder, cutting fatigue on long range sessions or hunts and letting you stay behind the gun longer without your arms crying uncle. Whether you're building a lightweight patrol rifle, a handy hunting gun, or a competition trainer, this barrel gives you the performance and flexibility to do it right.
Every barrel is magnetic particle inspected at the factory, so you know it's clean of internal defects before it ships. Faxon barrels have earned their reputation among shooters who demand real durability without the marketing noise. This is no-compromise hardware for folks who want their AR to work as hard as they do.
| Caliber | 5.56 NATO |
| Barrel Length (Rifled) | 14.5" |
| Overall Length (with Integral Muzzle Device) | 16" |
| Twist Rate | 1:8 |
| Profile | Gunner |
| Gas System | Mid-Length |
| Block Diameter | .625" |
| Muzzle Device Options | 3-Port Brake or Slotted Flash Hider |
| Quality Control | Magnetic Particle Inspected |
Yes. The integral muzzle device design lets you switch between a 3-port brake and slotted flash hider by hand. There's no pinning or welding involved, so you have full freedom to reconfigure whenever your needs change.
The Gunner profile combines the robustness of a Gov't profile with the reduced weight and better handling of a Pencil design. This hybrid brings the rifle's balance closer to your body, cutting fatigue during long range sessions or hunting days and making the gun more maneuverable without sacrificing durability.
This is a barrel assembly designed for AR-15 platform rifles. Consult your lower manufacturer or a gunsmith if you have questions about fitment with your specific build.
Magnetic particle inspection is a quality control process that detects internal defects like cracks or inclusions inside the steel. Every Faxon barrel undergoes this test before shipment to ensure you receive a sound, reliable component.
