In its simplest term, kinetic energy is the energy of motion. The 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 is 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 a wide variety of loads and under the full extremes of weather, temperature, moisture, and grime. This gun is designed to work, come hell or high water. The operation is clean because gases are sent out of the barrel and away from the action.
