International Classification:

F41A 9/03

Abstract:

A conveyor mechanism for use with ammunition rounds includes a plurality of clamshells pivotally interconnected to each other, with each clamshell including a first body and a second body pivotally connected to the first body. Each clamshell is selectively transitional between an ammunition holding configuration and an ammunition release position, with the second body pivoting relative to the first body to facilitate transition between the ammunition holding configuration and the ammunition release configuration. The first and second bodies are configured to cooperatively engage one of the ammunition rounds when the clamshell is in the ammunition holding configuration.
