Which agency regulates firearms, fireworks, and explosives in the United States?

The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) is the agency responsible for regulating firearms, fireworks, and explosives in the United States. The ATF oversees the enforcement of federal laws related to these areas, ensures compliance with regulations regarding the sale and distribution of firearms, and regulates the manufacturing, importation, and storage of explosives and fireworks. Additionally, the ATF plays a significant role in investigating violations of these laws to enhance public safety and prevent crime.

In contrast, the Federal Bureau of Investigation focuses on national security and federal criminal investigations, the Department of Justice oversees a broader scope of legal matters but does not specifically manage firearms or explosives, and the Drug Enforcement Administration primarily regulates controlled substances rather than firearms or explosives. This specialized focus of the ATF makes it the correct agency for this particular regulatory role.
