The purpose of this subpart is to establish policies and procedures implementing the Brady Handgun Violence Prevention Act (Brady Act), Public Law 103-159, 107 Stat. 1536. The Brady Act requires the Attorney General to establish a National Instant Criminal Background Check System (NICS) to be contacted by any licensed importer, licensed manufacturer, or licensed dealer of firearms for information as to whether the transfer of a firearm to any person who is not licensed under 18 U.S.C. 923 would be in violation of Federal or state law. The regulations in this subpart are issued pursuant to section 103(h) of the Brady Act, 107 Stat. 1542 (18 U.S.C. 922 note), and include requirements to ensure the privacy and security of the NICS and appeals procedures for persons who have been denied the right to obtain a firearm as a result of a NICS background check performed by the Federal Bureau of Investigation (FBI) or a state or local law enforcement agency.
