MBA

MBA refers to ammunition and projectile systems developed and marketed by MBA Associates and related entities, best known for unconventional ballistic concepts explored during the 1960s and 1970s. This category spans a wide range of designs, including Gyrojet rockets in multiple calibers, Lancejet and Lancejet-derived projectiles, and less lethal systems such as bean bag and stinger-style loads. Together, these items reflect a period of intense experimentation in propulsion, stabilization, and payload delivery that diverged sharply from conventional cartridge-based firearms.

Material in this category includes live, inert, dummy, fired, sectioned, and prototype examples, along with component bodies, test pieces, and loaded cases across handgun, launcher, and specialty formats. Variations in nozzle configuration, porting, materials, crimp styles, and projectile construction document both developmental iterations and limited production outcomes. From a collector and research perspective, MBA material is significant for illustrating one of the most ambitious alternative ammunition programs of the twentieth century, offering insight into experimental design paths, testing practices, and the practical limits encountered when introducing radically new ballistic systems.
