scope:

This specification covers one type of gun-driven feed mechanism for ammunition belted with M17 links for use on the 20mm, M61 and M61A1 automatic guns. The feeder pulls in the link-belted ammunition, strips the ammunition from the links, ejects the empty links, and feeds the delinked ammunition into the gun. The feeder includes an electrically operated declutching feature for clearing the gun of ammunition and switches for a rounds counter and a last round indicator.
