Abstract: A spare magazine carrier for carrying at least one ammunition magazine on a user's person. The spare magazine carrier has a carrier frame for seating and supporting at least one ammunition magazine, and a downwardly retractable flap for covering and retaining the seated ammunition magazine. The flap has an elastic member connecting a lower flap end with an upper flap end. The lower flap end is secured to a lower portion of the carrier frame, and the upper flap end is detachably securable to a top end of the carrier frame by resiliently extending over and around an upper exposed portion of the seated ammunition magazine in a preferably inverted U-shaped configuration. When the upper flap end is released, the elastic member causes the upper flap end to retract down and away from the opening, and thereby allow unobstructed access to the ammunition magazine.
