1. The Faxon Firearms AR-15 GUNNER Barrel combines the best features of Gov't and Pencil profiles for performance and versatility, with a focus on heat resistance and reduced whip.
2. Manufactured from 4150 Mil-Spec steel, the barrel undergoes rigorous testing including stress relief and air-gauge testing to ensure superior accuracy and quality.
3. With a 1:8 twist rate, QPQ Nitride finish inside and out, and compatibility with a .625" gas block, this 14.5" barrel is designed for the 5.56 NATO cartridge and includes an 11-degree target crown.

Designed by Faxon Firearms competition shooting staff for those who value performance and versatility, the GUNNER profile is a blend of two of the best performing profiles of all time, Gov't and Pencil.  The GUNNER's profile from the extension to the gas block mimics Government profile taper. From there, the GUNNER moves to a .625" gas block journal and a pencil profile out front. Removing the weight from the front of the barrel ensures maximum versatility and keeps material to the rear to maximize heat resistance and mitigate whip. Manufactured 100% in-house from cradle-to-grave, these barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.  Quality is imbued into our barrels from the start. Faxon starts with certified 4150 Mil-Spec steel and from there each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace by precision custom hardened gauges.  Faxon manufactures all their barrels in Cincinnati, Ohio under ISO:9001 and AS:9100  quality certifications.  Barrel Material: 4150 CMV Steel Barrel Type: Button Rifled  Barrel Caliber: 5.56 Barrel Twist: 1:8 Inside Finish: QPQ Nitride Outside Finish: QPQ Nitride Muzzle Thread: 1/2-28 TPI (Threads Per Inch)  Gas Block Diameter: .625"  Gas Port Diameter: .081" Gas Block Journal Length: 1.9" Barrel Extension: M4  Magnetic Particle Inspected 11-degree Target Crown
