You've got to be kidding me! Straw purchases and gun show loopholes have already put enough guns into the wrong hands. Dream on. At the pace the firearms industry evolves at, we're all going to be driving Hydrogen F350 SuperDutys before this ever happens.
Yup. It probably won't happen.
However, it's a fact that anyone who has an FFL is profiting from this. I can buy every single part of a gun off the Internet, just like a lot of other products, except for the frame or stripped receiver, depending on the gun. Were it not for GCA68, I'd just buy the whole thing off the 'net like I can buy a crossbow, and nobody gets his Federally-guaranteed cut of my purchase.
And furthermore, FFL's are happy to point out this crap about "guns in the wrong hands", as if the extra fee and the legally-mandated cut FFL's get of any interstate sales makes a damn bit of difference in the crime rate.
It's a self-serving game. Can't blame someone for "rent-seeking", I guess, but I don't have to like it, or them, for taking my money.
For an FFL to complain about something that makes it a bit harder, when he has a Federally-protected business with legally-limited competition, is pretty rich, though. For an FFL, who makes his living off Form 4473, to claim to be "refusing to sell" to a state that requires some extra paperwork, in the name of gun rights, is the height of hypocrisy.
If you make your money off the restrictions on RKBA, then you are a part of this problem, too. I'm not saying there's a good way around it; I'm saying, "methinks the man doth protest too much."
