The NRA created gun grabbing in their 1968 gun control act.
Prior to that there was no such thing on the national stage.
The NRA brought New York City laws to the entire nation.
.
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 National Rifle Association (NRA) 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.
The deaths of Martin Luther King Jr. in April 1968 and U.S. Senator Robert F. Kennedy in June 1968, along with fears of armed uprising in black cities, renewed efforts to pass the bill. On June 11, 1968, a tie vote in the House Judiciary Committee halted the bill's passage. On reconsideration nine days later, the bill was passed by the committee. The Senate Judiciary Committee similarly brought the bill to a temporary halt, but as in the House, it was passed on reconsideration. House Resolution 17735, known as the Gun Control Act, was signed into law by President Lyndon B. Johnson on October 22, 1968 banning mail order sales of rifles and shotguns and prohibiting most felons, drug users and people found mentally incompetent from buying guns.
AS for your claim: The NRA brought New York City laws to the entire nation., I think that may be a huge stretch.
