Potentially the world's most powerful automatic weapon, Metal Storm uses a system that combines gun barrel and magazine, so that the only moving parts are the projectiles themselves. Other automatic weapons have a magazine with bullets that are mechanically loaded into the barrel, but in the Metal Storm weapon, ammunition is preloaded and stacked in the combined barrel/magazine.

The bullets are fired electrically to generate a torrent of lethal force (up to thousands of rounds per second), especially with systems using a multibarreled configuration. This technology can be used for all types of munitions, and with no other moving parts, jamming is never a problem. Seen above is Metal Storm's remote-controlled Redback 40mm weapon system, recently introduced as a devastating counter to all types of threats.
