Abstract: The invention provides an apparatus for reducing recoil on a firearm or gun and to increase rate of firing. The invention uses a dual mass system to dynamically balance the gun wherein some of the energy of firing is absorbed within springs and thereby reduces the recoil force imparted to the gun user. The apparatus also comprises an ejector mechanism for ejecting a spent round and reloading a new round from the gun magazine with increased speed over conventional designs. The apparatus is applicable to automatic and semiautomatic handguns as well as rifles and machine guns.
