Which bureau provides information on firearm regulations?

The Bureau of Alcohol, Tobacco, and Firearms (ATF) is the federal agency primarily responsible for regulating firearms and enforcing laws related to their sale and possession. The ATF provides comprehensive information regarding the legalities of firearm ownership, sales procedures, and overall compliance with federal firearms regulations. They also handle the processing of firearm licenses and conduct investigations into firearm-related crimes.

In comparison, while the Federal Bureau of Investigation (FBI) is involved in various law enforcement activities, including background checks through the National Instant Criminal Background Check System (NICS), it does not specifically regulate firearms. The National Institute of Justice primarily focuses on research and development related to criminal justice rather than firearms regulations. The Alcohol and Tobacco Tax and Trade Bureau (TTB) oversees the taxation and trade of alcohol and tobacco but does not have authority over firearm regulation. Therefore, the ATF is the definitive resource for information on firearm regulations.
