To restore Second Amendment rights in the District of Columbia.

Second Amendment Enforcement Act - Amends specified law prohibiting the killing of wild birds and wild animals in the District of Columbia to declare that nothing in it or any other provision of law shall authorize or be construed to permit the Council, the Mayor, or any governmental or regulatory authority of the District to prohibit, constructively prohibit, or unduly burden the ability of persons otherwise not prohibited from possessing firearms under federal law from acquiring, possessing in their homes or businesses, transporting for legitimate purposes, or using for sporting, self-protection or other lawful purposes, any firearm neither prohibited by federal law nor subject to the National Firearms Act.

Includes also the frame or receiver of any such firearm, any part designed and intended solely and exclusively, or combination of parts designed and intended, for use in converting a firearm into a machine gun, and any combination of parts from which a machine gun can be assembled if such parts are in the possession or under the control of a
