Faxon Firearms Match Series AR-15 Gunner 300BLK 416R QPQ Nitride Barrel

The 300 Blackout cartridge yields increased performance in shorter barrels and effective subsonic performance. By speeding up the twist rate to 1:5 from common 300 BLK rates of 1:7 and 1:8, these Faxon Match Series Gunner Barrels increase projectile stabilization and energy on target.

The Gunner profile is a blend of two of the best performing profiles of all time, GOVT/SOCOM and Pencil. Faxon's Gunner profile combines the durability of the GOVT/SOCOM profile with the weight savings and maneuverability of the Pencil profile. The Gunner profile brings the balance of the rifle back towards the shooter's body, limiting fatigue, and allowing for shooting, training, or hunting all day long.
