An apparatus for holding a plurality of ammunition magazines in a stacked arrangement. The apparatus is configured to allow a magazine not in use in the stack to be disconnected from the stack while allowing a magazine engaged in the weapon to remain in place. The device comprises a clip located on one magazine sleeve that reversibly connects to a latch located on a second magazine sleeve. A magazine can comprise a latch on one side and a clip on an opposite side to permit stacks of more than two ammunition sleeves with magazines to be constructed. The clip and latch can be designed to provide variable spacing or staggering of magazines in order to adapt to weapons where space limitations require alternative configurations.
