The KRISS Vector is one of the most recognizable modern firearms in the world, largely due to its futuristic aesthetic and its unique engineering designed to solve a century-old problem: recoil. Developed by KRISS USA (formerly Gamma Research), it is a family of weapons based on a submachine gun design. 1. The Core Innovation: The Super V System The standout feature of the Vector is the KRISS Super V Recoil Mitigation System. In a traditional firearm, the bolt travels straight back into your shoulder, causing the barrel to "climb" upward. In the Vector, the action is re-routed. When a shot is fired, the bolt and a heavy slider move downward into a recess behind the magazine well. Vectoring Energy: By redirecting the blowback energy toward the ground rather than the shooter's shoulder, it significantly reduces felt recoil and muzzle climb. Controllability: This allows the user to fire high-caliber rounds (like .45 ACP) at high rates of fire with surprising stability.
