Abstract:
For use in a firearm having a cartridge chamber, a cartridge feed device comprising:a box magazine defining a transfer station and having an opening sized to pass a first cartridge in a direction transverse to a longitudinal axis of the first cartridge; a movable lip associated with the magazine, the lip being movable between a rest position wherein the lip at least partially blocks the opening, and a released position wherein the lip exposes the opening sufficiently to permit the first cartridge to pass therethrough; a magazine spring for biasing the first cartridge into the transfer station when the lip is in the rest position and for forcing the first cartridge out of the opening toward an intermediate station when the movable lip is moved from the released position to the rest position; a feed fork for transversely lifting the first cartridge from the intermediate station to a feed station behind the cartridge chamber; and a breech for longitudinally advancing the first cartridge from the feed station into the cartridge chamber, wherein the movement of the first cartridge from the transfer station to the feed station is substantially transverse to the longitudinal axis of the cartridge.
