Garand Shooter-
Not so quick to gloat my friend. I believe SBR's are still OK. Check this out, from the SC law...
MACHINE GUNS
A machine gun is defined as "any weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger." It also includes "the frame or receiver of any such weapon, any combination of parts designed and intended for use in converting a weapon into a machine gun and any combination of parts from which a machine gun can be assembled if such parts are in the possession or under the control of a person."
Persons allowed to possess machine guns include members of the armed forces, the National Guard, law enforcement officers, railway policemen, and persons whose employment involves keeping custody of prisoners. Other persons may possess machine guns kept for display as relics and which are rendered harmless and not usable. All machine guns, operable or nonoperable, must be registered with the State Law Enforcement Division.
