Why not let those THAT WANT TO get a universal firearms buyer card? Just like a drivers license, good for xx number of years, includes a background check, can be used at gun stores, gun shows, etc. As long as someone has this card they can immediately purchase any weapons/ammo they want - no need for waiting periods, any other background checks, etc. NO record of WHICH or HOW MANY weapons or ammo someone buys. If you don’t want to get the card, fine, then you still go through the regular background checks, etc. every time you buy a weapon.
A firearms buyer card could be easily faked, plus to get one, the buyer would have to be registered somewhere. I don’t like the idea.
