Abstract: A safe and reliable multi-component projectile enables cost effective manufacturing and assembly of the projectile. Major components of the projectile are joined by a plurality of shear pins interfacing with scalloped geometry of the components. The components are then held together by forcibly joining them using a hybrid annular-cantilevered snap fit joint. The tooth and groove arrangement exists where the teeth are at the end of a spring-leaf like feature of one of the mating parts and the groove is located on the opposite mating part.
