The module explains that there are thousands of firearm models which have been given collector-status by ATF as Curios and Relics (C&R) . This category has been confused with “Antique Firearms” (non-guns) by some people, with very costly consequences, both financially and criminally. It is ironic that a few of them actually do qualify as non-guns. Unlike guns outside this category, C&Rs occupy a status which allows them to be sold without the buyer completing the otherwise necessary Government forms, and to residents of other States. There are numerous pitfalls concerning them, as they exist within the GCA and some within the NFA. They also only qualify for some of these exceptions for people holding a special ATF-issued license. C&Rs are an otherwise very confusing area, but which are made clearly understandable here.
