Relating to the prosecution of the criminal offense of the possession, manufacture, transport, repair, or sale of a machine gun or a machine gun conversion device.

SB 808 amends Texas law to make it a crime to possess, manufacture, transport, repair, or sell a machine gun conversion device (a part that turns a regular gun into a machine gun). It directly affects gun owners, dealers, and collectors who handle such devices. The bill adds conversion devices to the list of prohibited items under Section 46.05 of the Penal Code, with an exception allowing possession if the device is registered with the federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) or classified as a "curio or relic" by the U.S. Department of Justice. The law would take effect September 1, 2025, and applies only to offenses committed after that date.
