Having watched O'Reilly on and off for years, I've noticed that when it comes to firearms, he's more often than not woefully misinformed. I would not be surprised to learn that he does not know the difference between a NICS check and registration and simply assumes that one equates to the other. While he often brings up valid points on other issues, I take most, if not all, of what Bill O'Reilly says about guns and the Second Amendment as worth a large grain of salt.
