ABSTRACT:
An automatic gas-operated forward recoiling combat shotgun has a reciprocally movable barrel which includes a bore and a revolving magazine which defines a circumaxially spaced series of firing chambers. In firing position, one of the firing chambers is coaxially aligned with and forms a rearward extension of the bore. A cam actuated indexing mechanism sequentially positions each of the firing chambers in firing position in response to reciprocal movement of the barrel. A manually reciprocally movable foregrip functions to cock the shotgun firing mechanism and also cooperates with the trigger mechanism to release the magazine when the forearm is operated while the trigger held in a firing position. A cocking trigger enables silent cocking or uncocking of the firing mechanism. The casing of each shell forms a seal between an associated firing chamber and the barrel when the weapon is fired.
