The GCA created what is known as the "sporting purposes" standard for imported firearms, saying that they must "be generally recognized as particularly suitable for or readily adaptable to sporting purposes." GCA sporting purposes includes hunting and organized competitive target shooting, but does not include "plinking" or "practical shooting" (which the ATF says is closer to police/combat-style competition and not comparable to more traditional types of sports), nor does it allow for collection for historical or design interest.[19][20]:16-18 Hence, foreign made assault rifles and machine guns such as the AK-47, the FN FAL or the Heckler & Koch MP5 could no longer be imported into the United States for civilian ownership (however, semi-automatic models of the same weapons were permitted until the definition of sporting purpose was further tightened in 1989).
