v t e

In the United States, the right to keep and bear arms is modulated by a variety of state and federal statutes. These laws generally regulate the manufacture, trade, possession, transfer, record keeping, transport, and destruction of firearms, ammunition, and firearms accessories.^[1] They are enforced by state, local and the federal agencies which include the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).

The private right to keep and bear arms is protected by the Second Amendment of the United States Constitution. This protection became legally explicit when the U.S. Supreme Court ruled in District of Columbia v. Heller (2008) that the Amendment defined and protected an individual right, unconnected with militia service. A subsequent holding in McDonald v. City of Chicago (2010) ruled that the Second Amendment is incorporated by the Due Process Clause of the Fourteenth Amendment and thereby applies to state and local laws. In New York State Rifle & Pistol Association, Inc. v. Bruen (2022) the Court struck down New York's may-issue policy of being required to show "proper cause" to be granted a concealed carry license, but allowed states to enforce "shall-issue" permitting where applicants must satisfy certain objective criteria such as passing a background check. It also held that any regulation of firearms in the United States is presumed unconstitutional unless the state can prove it is rooted in the country's text, history, and tradition. In United States v. Rahimi (2024), this test was refined as the Court upheld federal laws restricting gun rights from those accused of domestic violence and said that lower courts should not seek exact comparisons when reviewing the historical tradition but rather look at similar analogues and general principles.^[2]
