House Bill 1587, also known as Senate Bill 2952, proposes an amendment to the Tennessee Code Annotated regarding firearms, specifically focusing on the regulation of semi-automatic rifles. The bill defines a "semi-automatic rifle" and establishes that it is an offense to knowingly manufacture such a firearm within the state. Violating this provision would result in a Class A misdemeanor charge.

The bill is set to take effect on July 1, 2023, contingent upon the public welfare. This legislation aims to enhance firearm regulations in Tennessee by prohibiting the manufacturing of semi-automatic rifles, thereby addressing concerns related to gun violence and public safety.
