Bill > SB421

This bill modifies Missouri state law regarding firearm accessories by adding a new definition and legal restriction for "rapid fire devices," which are defined as any accessory, conversion kit, device, or tool that attaches to a semiautomatic firearm and allows it to discharge multiple shots when activated, or increases the firearm's rate of fire. The bill updates Section 571.010 to include this new definition as item (16) in the list of firearm-related terms, and amends Section 571.020 to make possessing a rapid fire device a criminal offense, specifically a class D felony. The new provisions align with existing restrictions on other firearms and accessories like machine guns, short-barreled rifles, and switchblade knives. The bill maintains existing exceptions for official duties, lawful commercial transactions, industrial use, museum displays, and dramatic performances, ensuring that certain authorized uses of such devices remain legal. These changes appear intended to regulate potentially dangerous firearm modification tools that could increase a semiautomatic weapon's firing capability.
