Abstract
A machine gun in which controlled chamber pressure and weapon recoil, through suitable linkages, connections, and controls, turn a crankshaft to which the breechblock is connected. As a result, the breechblock moves sinusoidally, thereby permitting gentle handling of ammunition, higher firing rates, and positive firing rate control, from very low to very high rates. The machine gun has at least one barrel, with a breechblock for each barrel.
