Federal Firearms License
Depends on where you are, and the laws that govern that place. In MOST of the US, no license is required. However, in firearms, "antique" has a legally defined meaning. Firearms that use loose powder and ball are antiques regardless of age. Cartridge firearms made prior to 1899 are antiques. They are NOT firearms under Federal law- they are Antique Firearms, and in most ways, treated as if they were not guns.There IS a Federal Firearms License for Collectors- known as a C&R or an 03 Curio and Relics Collectors License. It is not required, but permits a collector to buy firearms from another state and have them shipped directly to them. It covers firearms that are 50 years old or older.
