Assault Weapons Ban of 2023

This bill would ban the sale, manufacture, transfer, and possession of most semiautomatic rifles, pistols, and shotguns meeting specific criteria defined as "assault weapons," as well as large capacity ammunition magazines holding more than 10 rounds. The ban would not apply to weapons already owned before enactment, or to certain types like bolt-action rifles, antique firearms, or weapons used by law enforcement. The bill would require identification markings on new assault weapons and magazines, require background checks for transfers of "grandfathered" weapons, and authorize federal buy-back programs for banned weapons through Byrne grants. It includes exemptions for military, law enforcement, and certain historical firearms.
