Gun law in the United States
Gun laws of the United States are found in a number of federal statutes. These laws regulate the manufacture, trade, possession, transfer, record keeping, transport, and destruction of firearms, ammunition, and firearms accessories. They are enforced by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).
The right to keep and bear arms is protected by the Second Amendment to the United States Constitution.
Major federal gun laws
- National Firearms Act ("NFA") (1934): Taxes the manufacture and transfer of, and mandates the registration of Title II weapons such as machine guns, short-barreled rifles and shotguns, heavy weapons, explosive ordnance, silencers, and disguised or improvised firearms.
- Omnibus Crime Control and Safe Streets Act of 1968 (1968): Prohibited interstate trade in handguns, increased the minimum age to 21 for buying handguns.
- Gun Control Act of 1968 ("GCA") (1968): Focuses primarily on regulating interstate commerce in firearms by generally prohibiting interstate firearms transfers except among licensed manufacturers, dealers and importers.
- Firearm Owners Protection Act ("FOPA") (1986): Revised and partially repealed the Gun Control Act of 1968. Prohibited the sale to civilians of automatic firearms manufactured after the date of the law's passage. Required ATF approval of transfers of automatic firearms.
- Undetectable Firearms Act (1988): Effectively criminalizes, with a few exceptions, the manufacture, importation, sale, shipment, delivery, possession, transfer, or receipt of firearms with less than 3.7 oz of metal content.

- Brady Handgun Violence Prevention Act (1993): Requires background checks on most firearm purchasers, depending on seller and venue.
- Federal Assault Weapons Ban (1994–2004): Banned semiautomatic assault weapons and large capacity ammunition feeding devices. The law expired in 2004.
- Protection of Lawful Commerce in Arms Act (2005): Prevent firearms manufacturers and licensed dealers from being held liable for negligence when crimes have been committed with their products.
In the United States the right to keep and bear arms is protected by the Second Amendment to the Constitution. While there have been vigorous debates on the nature of this right, there was a lack of clear federal court rulings defining the right until two relatively recent United States Supreme Court cases.
An individual right to own a gun for personal use was affirmed in the landmark District of Columbia v. Heller decision in 2008, which overturned a handgun ban in the Federal District of Columbia. In the Heller decision, the court's majority opinion said that the Second Amendment protects "the right of law-abiding, responsible citizens to use arms in defense of hearth and home." However, in delivering the majority opinion, Justice Antonin Scalia wrote:
Like most rights, the Second Amendment right is not unlimited. It is not a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose: For example, concealed weapons prohibitions have been upheld under the Amendment or state analogues. The Court’s opinion should not be taken to cast doubt on longstanding prohibitions on the possession of firearms by felons and the mentally ill, or laws forbidding the carrying of firearms in sensitive places such as schools and government buildings, or laws imposing conditions and qualifications on the commercial sale of arms.
The four dissenting justices said that the majority had broken established precedent on the Second Amendment, and took the position that the Amendment refers to an individual right, but in the context of militia service.
In the McDonald v. City of Chicago decision in 2010, the Supreme Court ruled that, because of the incorporation of the Bill of Rights, the guarantee of an individual right to bear arms applies to state and local gun control laws and not just federal laws.
The Supreme Court has not ruled on whether or not the Second Amendment protects the right to carry guns in public for self defense. Federal appeals courts have issued conflicting rulings on this point. For example, the U.S. Seventh Circuit Court of Appeals ruled in 2012 that it does, saying, "The Supreme Court has decided that the amendment confers a right to bear arms for self-defense, which is as important outside the home as inside." But the Tenth Circuit Court ruled in 2013 that it does not, saying, "In light of our nation's extensive practice of restricting citizen's freedom to carry firearms in a concealed manner, we hold that this activity does not fall within the scope of the Second Amendment's protections."
The following persons are eligible to possess and own firearms within the United States: US citizens, permanent resident aliens or non-immigrant aliens admitted into the United States for lawful hunting or sporting purposes or if they fall under one of the following exceptions: possesses a valid hunting license or permit issued by any US state, an official representative of a foreign government who is accredited to the United States Government or the Government’s mission to an international organization having its headquarters in the United States or is en route to or from another country to which that alien is accredited, an official of a foreign government or a distinguished foreign visitor who has been so designated by the Department of State, or a foreign law enforcement officer of a friendly foreign government entering the United States on official law enforcement business

Justice Stevens begins his opinion by conceding Justice Scalia's point that the Second Amendment right is an 'individual' one, in the sense that '[s]urely it protects a right that can be enforced by individuals.' He concludes, however, that all of the historical context, and all of the evidence surrounding the drafting of the Second Amendment, supports the view that the Second Amendment protects only a right to keep and bear arms in the context of militia service.

In both dissents, the clear implication is that if the purpose of the Second Amendment is militia—related, it follows that the amendment does not create a legal rule that protects an individual right to possess and carry fire arms outside the context of service in a state militia.

Justice John Paul Stevens argued that the debate over the Second Amendment was not whether it protected an individual or collective right but, instead, over the scope of the right to bear arms.
