Check out the Gun Control Act of 1968 which was greatly shaped by the NRA (cut down from a stricter version, but they were OK with banning gun ownership by felons), the Mulford Act which prohibited carrying loaded weapons in public in California and passed with bipartisan support (signed into law by none other than Ronald Reagan), and the 1994 Federal Assault Weapons ban (which didn't have Republican support in Congress but did have support from both Reagan and Gerald Ford).
