The Gunner profile is a blend of two of the best performing profiles of all time, Gov't and Pencil. Faxon's Gunner profile combines the durability of the Gov't 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.Specifications: Manufacturer: Faxon Firearms Finish: Chrome Cartridge: .300 AAC Blackout Barrel Length: 10.5 in Gas System Length: Pistol Length Gas Block Journal Size-Diameter: .750 in Barrel Twist Rate: 1-8 Weight: 1.1 lb Gas Block Journal Size-Length: 1.9 in
