The "District of Columbia Firearm Freedom Act" seeks to overhaul firearm regulations in the District of Columbia, asserting Congress's plenary authority over the District and the individual right to keep and bear arms. It aims to eliminate existing prior restraints on firearm acquisition and possession, meaning individuals would no longer need a license, certificate, or permit from the District before obtaining or possessing a firearm. A central provision is the repeal of the District's firearm registration system , requiring the destruction of existing registration records and prohibiting the establishment of any similar future schemes. The bill also prohibits the District from banning firearms based on features like being semiautomatic, having a detachable magazine, or other cosmetic attributes, effectively preempting "assault weapon" bans. It further repeals the prohibition on large capacity ammunition feeding devices . A significant change is the establishment of concealed constitutional carry , allowing non-prohibited persons aged 21 or older to carry a concealed handgun without a District-issued license or permit, though private property owners can still restrict firearms. Finally, the legislation facilitates firearm purchases for District residents by amending federal law to treat them as "in-state" buyers when purchasing from federally licensed dealers in Virginia or Maryland, subject to federal background checks.
