Which agency is responsible for enforcing federal firearms regulations?

The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) is the agency specifically designated to enforce federal firearms regulations. This includes overseeing the regulation of firearms, explosives, and other alcohol and tobacco-related laws. The ATF is responsible for investigating and preventing violations of laws related to the sale, possession, and use of firearms across the country.

In addition to enforcement, the ATF plays a crucial role in the licensing and regulation of firearms dealers and maintaining the National Firearms Registration and Transfer Record. This agency conducts inspections and investigations to ensure compliance with federal laws and regulations concerning firearms, showcasing its central role in maintaining the legal framework surrounding gun ownership and distribution in the United States.

Other agencies, such as the FBI and DOJ, may have roles in firearms-related investigations or prosecutions, but they do not have the same focused jurisdiction or responsibility for enforcing federal firearms laws as the ATF does. The NSA, primarily responsible for national security and intelligence gathering, does not engage with matters related to firearms regulations.
