These 20mm XM254 dummy cartridges are of heavy plastic exterior construction with a steel head and steel internal filling to exactly duplicate the weight of live cartridges. These contain no fuse, primer, or any form of charge and are 100% inert. The XM254 dummy cartridges were used in crew training to reduce wear on component and firing mechanisms; used with the following 20mm guns: M39, M61, M139, M168, M195 and XM197.

Note: Due to age and storage, the plastic cartridge steel bases are corroded and the hulls are stained, dinged, scratched or may even have their tips chipped. The belt links are almost uniformly covered in surface rust.
