Faxon Firearms Duty Series Gunner 11.5 inch 5.56 NATO AR-15 Barrel, Black Nitride 15A58M11NGQ
Product Description
The Faxon Firearms Duty Series Gunner Profile 11.5 inch 5.56 NATO barrel is built for lightweight AR-15 builds that still need long-term durability, including suppression-focused setups. Its Gunner contour uses a Government-style taper behind the gas block for strength where it counts, then transitions to a straight forward section with a full shoulder and standard 1/2-28 muzzle threads for secure muzzle device and suppressor mounting. Manufactured in-house from certified 4150 CMV steel and finished in black nitride inside and out, this barrel is fully stress relieved, air-gauge tested, and individually headspace checked for consistent performance.
Product Highlights
- Lightweight Gunner profile design helps reduce front-end weight while maintaining structural integrity.
- Black nitride finish inside and out enhances corrosion resistance and long-term wear durability.
- Button-rifled 1:8 twist rifling offers versatile performance across common 5.56 NATO projectile weights.
- Mid-length gas system on an 11.5 inch barrel supports balanced function for compact builds.
- Quality control includes stress relief, air-gauge testing, magnetic particle inspection, and headspace verification.
