Notes

Note 1 to 0A509.b and .c: Receivers (frames) under 0A509.b and .c refers to any “part” or “component” of the firearm that has or is customarily marked with a serial number when required by law. Paragraph 0A509.b and .c are synonymous with a “part” or “component” that is regulated by the Bureau of Alcohol, Tobacco, Firearms and Explosives (see 18 U.S.C. 921(a)(3); 27 CFR parts 447, 478, and 479,) as a firearm. For 0A509.c, receivers (frames) includes chassis “components” that serve as the legal firearm ( i.e., with modern pistols, the chassis itself is the serialized firearm).
