The South Carolina National Firearms Act (SCN FA) is a state law that regulates the ownership and use of certain firearms. The SCN FA defines and restricts the types of firearms that can be owned and used by citizens in South Carolina, as well as the process for obtaining registration for those firearms. The Act includes a licensing requirement for certain firearms, such as machine guns, silencers, and short-barreled rifles and shotguns. It also includes a background check and registration process for those firearms. The SCN FA also imposes restrictions on the transfer of firearms and sets forth additional rules and regulations for the storage and handling of firearms. The three main types of firearms regulated by the SCN FA are machine guns, short-barreled rifles and shotguns, and silencers.
