This disclosure relates to a system and method for storage of a modular cartridge within a cavity formed in a portion of a firearm, wherein the cavity is not the magazine well of the firearm. The disclosure provides for a system for disengagebly retaining such modular cartridges, as well as multiple embodiments of cartridges which may be retained therein. Such embodiments of modular cartridges include: a miniature magazine (mini-mag) which may be used to store ammunition, and which may be operable as a magazine for the firearm; a dry box which may be used to store materials in a manner in which they are protected from the ambient environment; a monopod which may be used to help support a firearm; a flashlight; and a battery charger, which may provide for a usb output.

A rifle holder hinge mechanism comprising a support block with rifle hook attached thereto, the support block having a sleeve for receiving a hinge pin, and a hinge block, the hinge block having a hinge block sleeve, with a hinge pin rotatable within the hinge block sleeve. The support block further comprises a projection or detent, and the hinge block further comprise a cutaway or recess configured to receive the detent and limit rotation of the detent of the support block relative to the hinge block. Rotation may be limited 90 degrees such that the rifle holder hinge mechanism has a first position for receiving a weapon and a second position when it is not in use.

A retractable stand comprises a base, two ribbons, and a locking mechanism. Each ribbon has a coiled portion and an uncoiled portion. The uncoiled portions have a curved cross-sectional shape positioned in opposing relation to each other. The locking mechanism is movable between an unlocked position and a locked position where the at least one ribbon is substantially inhibited from moving relative to the base in at least one direction. The locking mechanism can comprise an auto-locking member biased toward the locked position. The locking mechanism can further comprise a trigger mounted on the base and accessible by the user to move the auto-locking member to the unlocked position. Preferably, the retractable stand further includes a manual locking mechanism that can be manually selectively moved between unlocked and locked positions to selectively lock and unlock a position of at least one of the ribbons relative to the base.
