Background technique

A shotgun is a smooth-bore weapon that launches multiple projectiles or warheads in a cluster. It has the characteristics of large caliber, fierce firepower at close range, and high hit probability. It can perform saturated shooting on the target. Guns are more advantageous. Shotguns can be seen in all previous wars, but due to their relatively short effective range, they cannot become the main weapon of infantry. However, with the changes in the world situation, the form of war has also changed. The combat tasks of the military and police forces of various countries have shifted to respond to local conflicts, combat terrorist activities, and stop violent crimes. The combat characteristics of shotguns in specific scenarios can be get the most out of it.

Metal Storm's "stack ammunition" technology can be described as a very innovative and revolutionary technology in the field of light weapons in recent years. One of the most significant breakthroughs in ballistics. The firing of traditional shotgun ammunition requires a complex mechanical structure, slow rate of fire, and large recoil.
