Bill > HB548

This bill modifies Missouri's laws regarding firearm suppressors (also known as silencers) by introducing several key provisions. The bill expands the legal definition of firearm suppressors and creates new state-level regulations that aim to exempt locally manufactured suppressors from federal regulation. Specifically, a firearm suppressor would be considered "manufactured in Missouri" only if it is made entirely within the state using basic materials, with the exception of minor generic parts. The bill requires that any Missouri-made suppressor be stamped with "Made in Missouri" and prohibits state and local government entities from enforcing federal regulations on suppressors that are more restrictive than Missouri state law. The legislation also provides a mechanism for citizens to file complaints with the Attorney General if they believe a government entity is inappropriately enforcing federal suppressor regulations, and it includes potential financial penalties for entities that do so. Additionally, the bill effectively decriminalizes previous offenses related to firearm suppressors, stating that such offenses cannot be prosecuted after August 28, 2025, and any pending criminal actions for such offenses will be dismissed on that date. The overall intent appears to be creating a state-level framework that challenges federal firearm suppressor regulations and promotes local manufacturing of these devices.
