  • Patent number: 4707941
    Abstract: A quick load magazine and loading process are described by which bulk cartridges can be transferred from a cartridge box to a magazine and from the cartridge magazine to the firing mechanism of a firearm in a quick and efficient manner. The magazine includes mechanisms facilitating a loading process by which the cartridge box is successively opened and cartridges are dropped gravitationally into the magazine as the box is opened. Guide mechanisms receive the cartridges within the magazine and align the cartridges into successive substantially parallel columns. Spring mechanisms bias the columns toward a magazine interface that is received by the magazine well of the associated firearm. Springs urge the columns upwardly such that one column of cartridges is fed through the interface to the firing mechanism of the weapon until depleted.
