Faxon Duty Series Gunner 14.5" Mid-Length 5.56 NATO AR-15 Barrel 1:8 QPQ Black

The Faxon Duty Series 14.5" Gunner Profile 5.56 NATO barrel combines the rigidity of the Government contour with the lightweight handling of the Pencil profile. The hybrid design shifts the rifle’s balance point back toward the shooter for improved control, reduced fatigue, and superb accuracy—ideal for pin-and-weld builds to reach 16" overall length.

Key Benefits

• Balanced Gunner profile: Merges Government and Pencil contours for an ideal weight-to-rigidity ratio.
• Mid-length gas system: Smooth cycling with optimized gas pressure for reliability.
• Pin-and-weld compatible: 14.5" length is designed to reach 16" OAL once a muzzle device is permanently attached.
• Durable and precise: Fully stress relieved, air-gauge tested, and magnetic particle inspected.
• Corrosion resistant: Inside and out black nitride finish (QPQ).
• Made in Cincinnati, Ohio: Precision-engineered from 4150 CMV steel and individually headspace checked.
