The Gun Disabling Mock Ammunition is a device made to the same outward dimensional specifications and aesthetic characteristic as actual firearm ammunition; however, when attempted to be fired from a firearm, the effect is a non-hazardous, exothermic reaction taking place within the ammunition cartridge, producing heat substantial enough to bond the Gun Disabling Mock Ammunition to the inside of the chamber of the firearm, rendering the firearm immediately disabled and the chamber destroyed. This is accomplished while posing no risk of injury to the user or bystanders. The components of the Gun Disabling Mock Ammunition are non-toxic, non-hazardous, and chemically stable. Through use of the Gun Disabling Mock Ammunition, a reduction of deaths, injuries and crimes resulting from the intentional and unintentional use and access of unsecured legal, illegal and insurgent-force firearms can be achieved.
