Abstract:
1. A magazine assembly for firearm cartridges, comprising: a plurality of side by side tubular members each capable of receiving a plurality of cartridges, the tubular members being non-displaceably fixed with respect to a firearm upon which the magazine assembly is mounted; a generally hollow monoblock member, having a plurality of side-by-side, generally tubular portions extending therethrough and being axially coupled to an end of each of the tubular members, the monoblock providing a cartridge loading port and a cartridge feed port for each of the coupled tubular members; a plurality of independent gate members pivotally mounted at an end region of the monoblock and each having a biased first blocking member near an opening of a corresponding one of the cartridge feed ports and into the feed path of an end cartridge, the gate members co-operable with a cocking portion of the firearm to displace one of the first blocking members from the feed path during actuation of the cocking portion; and at least one cartridge interrupter pivotally mounted to the monoblock and located intermediate the cartridge feed ports, the cartridge interrupter having a pair of shouldered opposing sides and being pivotable to cause each shoulder to project into a corresponding feed port upon impingement of the opposing shoulder by a cartridge in one of the opposing tubular members for preventing the simultaneous feeding of cartridges from opposing feed ports during actuation of the cocking portion.
