The Kinematic Drive™. In its simplest term, kinetic energy is the energy of motion. The new Browning A5 makes better use of kinetic energy with its powerful, short recoil-operated Kinematic Drive System. Kinematic Drive harnesses recoil energy and converts it into the mechanical motion needed to operate the action. This concept is tried and true, and now perfected by the company that broke ground first with autoloading shotguns. The beauty of Kinematic Drive is the simplicity of design for consistent, reliable function with any load and under the full extremes of weather, temperature, moisture and grime. This gun is designed to work, come hell or high water. Operation is clean because gases are sent out the barrel and away from the action. There’s also extreme load versatility. The extensively tested Kinematic Drive offers reliable performance with virtually all loads down to 1-ounce field loads with no adjustments.
