…the right of the people to keep and bear Arms, shall not be infringed.

Today in History, May 19: 1986 – President Ronald Reagan signs the “Firearms Owners Protection Act” in to law. The Legislation, while effectively banning machine guns from private ownership, primarily responded to complaints from the public and the nascent NRA regarding abuses of the “Gun Control Act of 1968.”

The act by Congress attempted to protect the rights of peaceful firearms owners and also those possessing Federal Firearms Licenses (FFL), or firearms dealers.
