Bill > HB2316

This bill amends Missouri's existing firearm laws by adding a new definition for "machine-gun conversion device" and prohibiting its possession. Specifically, the bill defines a machine-gun conversion device as any device designed to convert a firearm into a machine gun, including examples like an auto sear or Glock switch. Under the new provisions, possessing such a device would be classified as a class D felony. The bill updates existing statutes by inserting this new definition into section 571.010 and adding machine-gun conversion devices to the list of prohibited items in section 571.020. The law maintains existing exceptions for official duties, lawful commercial transactions, and certain authorized uses by military, law enforcement, and other specified entities. By criminalizing these conversion devices, the bill aims to prevent individuals from modifying firearms to fire multiple shots automatically with a single trigger pull, which is currently illegal under the definition of a machine gun.
