Abstract
A double barrel break-action shotgun includes a firing mechanism having a rebound system in which the hammers rebound after firing into a position permitting opening of the gun and are not stressed by the associated mainsprings after the gun is fired. Because the hammers are not stressed in their released positions, they can be easily replaced with different hammers, thus rendering the gun easily convertible for different uses. A simple selector switch is also provided behind the trigger and does not require any wire or complex connections between the switch and the acorn. The bolt actuator includes a simple cam actuator which is detachable from the lever and which is simple to assemble and to replace. Compensation for bolt wear can be achieved by replacing the actuator with one having a surface of a different shape. The breech and breech housing include a bifurcated lug which absorbs recoil forces which would otherwise be imposed on the pivot pin. A portion of the lug can be replaced, thus maintaining close tolerances between the breech and breech housing.
