Product Description
The Faxon Firearms Big Gunner 16" 8.6 Blackout barrel is built from 4150 mil-spec steel and finished with salt bath nitride for durable, hard-use AR-10 builds. Each barrel is button rifled and individually checked for headspace using precision gauges, then final inspected to help ensure reliable fit and function. The Big Gunner profile balances handling and stiffness, while the carbine-length gas system, 11-degree target crown, and M18x1.5 muzzle threads (with tapered shoulder) make it a strong option for practical accuracy-focused and suppressor-ready configurations (verify alignment and compatibility before use).
