Patent attributes
A magazine assembly (10) for receiving and storing cartridges (28) for a firearm (1). At least one gate member (58, 60) is pivotally mounted at an open end of a monoblock (20) and has a first blocking member (58.1, 60.1) to inhibit feeding of an end cartridge from a feed port until the firearm (1) is cocked. The gate member (58, 60) further includes a second blocking member (58.4, 60.4) to prevent multiple cartridges (28) from feeding from the same feed port (20.3, 20.4) during a given cocking cycle. The gate member (58, 60) is operable to displace the first blocking member (58.1, 60.1) out of a cartridge feed path while placing a second blocking member (58.4, 60.4) in the feed path to of the next cartridge (28) to be fed. An interrupter (62) prevents cartridges (28) supplied by a plurality of feed ports (20.3, 20.4) from being fed simultaneously.
