Guns are not the problem. A proliferation of guns, gotten too easily into the wrong hands are the problem. The NRA was against waiting periods for criminal checks, against banning even the most dangerous weapons from getting to the public, oppose any efforts to hold gun conventions to the same laws that apply to gun shops, and are against requirements for registration of weapons. In short the NRA has been against every legislation aimed at gun owners. They want zero control of weapons.
Their big argument that only criminals will have guns is ludicrous for two reasons. First, not even the most extreme gun control fanatic supports a total ban of guns (at least not the ones that are elected to office). Secondly, to say that because a law is broken that it should be striken from the books is ludicrous. The laws against murder have not stopped some from commiting murder. Yet noone believes that the crime of murder should be taken off the books. Should we pander to criminals and make their jobs easier?
