Johnson on October 22, 1968, and is Title I of the U.S. federal firearms laws . The National Firearms Act of 1934 (NFA) is Title II . Both GCA and NFA are enforced by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). </P> <P> Passage of the Gun Control Act was initially prompted by the assassination of U.S. President John F. Kennedy in 1963 . The President was shot and killed with a rifle purchased by mail - order from an ad in the magazine American Rifleman . Congressional hearings followed and a ban on mail - order gun sales was discussed, but no law was passed until 1968 . At the hearings NRA Executive Vice-President Franklin Orth supported a ban on mail - order sales, stating, "We do not think that any sane American, who calls himself an American, can object to placing into this bill the instrument which killed the president of the United States ." </P>
