This final rule makes technical amendments and corrects typographical errors in parts 447, 478, 479, 555, and 646 of title 27, Code of Federal Regulations (CFR). These amendments do not change ATF's existing authorities or responsibilities. Many of the technical changes are being made to reflect changes in terminology that resulted from the transfer of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to the Department of Justice from the Department of the Treasury pursuant to the Homeland Security Act of 2002. The changes are designed to provide clarity and enhance uniformity throughout these regulations.
