Keep Americans Safe Act

Prohibits the import, sale, manufacture, transfer, and interstate/foreign-commerce possession of defined “large capacity ammunition feeding devices,” creates a statutory definition of that device (excluding a tubular .22 rimfire exception), requires identification markings and expands seizure/forfeiture authority, and creates a limited law‑enforcement and government exception. It also allows Byrne grant funds to be used for buyback payments for surrendered devices and includes a severability clause.
