I was floored when they allowed them in the first place. Seemed like a decision that was ripe for reversal from the day they made it.

The problem is that there a boatload of them out in the wild, many of them purchased with cash and no record of the sale. How do you put that genie back in the bottle?

My solution? Add them to the NFA registry. Tell folks they have X amount of time to either turn them in or register them. Make the tax fee reasonable . . . say $50-$75 . . . and the penalty for possession severe. Sort of like the "Any Other Weapons" on the NRA registry (i.e. Auto and Burglar). The fee for those is only $5 (established in 1935).
