Which federal law regulates the sale of firearms in the United States?

The Gun Control Act of 1968 is the federal law that regulates the sale of firearms in the United States. This legislation established comprehensive guidelines regarding the sale, transfer, and possession of firearms, aiming to promote public safety and reduce gun violence. It requires federal licensing of firearm dealers, sets age restrictions for the purchase of firearms, and outlines prohibited persons who cannot legally acquire firearms.

In contrast, while the Second Amendment is a constitutional provision that protects the right to keep and bear arms, it does not provide specific regulations regarding the sale of firearms. The Brady Act, enacted later in 1993, is significant but primarily focuses on background checks and waiting periods for firearm purchases rather than the overall framework for firearm sales established by the Gun Control Act. The Firearm Owner's Protection Act of 1986 made certain adjustments and protections relevant to gun owners, but it did not create the regulatory framework for firearm sales that the Gun Control Act established. Thus, the Gun Control Act of 1968 is the correct reference for the law governing the sale of firearms in the U.S.
