Abstract
A magazine configured for use with a 22 caliber conversion kit and/or a non-converted 22 caliber firearm includes an elongate, hollow, rectangular housing for receiving an ammunition belt on a splined belt pulley. A slide of the firearm applies an impact force to a strike wheel to pivot a cam against a spring-loaded rack. The rack moves downward and causes a rack gear to rotate a drive gear freely in the slip direction of a unidirectional bearing. When the impact force is removed, the spring-loaded rack returns upward under the biasing force of the spring causing the rack gear to rotate the drive gear on the unidirectional bearing in the drive direction. The drive gear turns a drive axle, which turns the splined belt pulley to advance the ammunition belt sufficiently to position the next round of ammunition for entry into the firing chamber.
