Last I checked, aren’t you already required to send a firearm to an FFL if it’s purchased over the internet and you’re mailing it to someone?
Of course, this is hardly the first time big brother had its head up its @$$ when it comes to knowing a law is already on the bloody books.
That is required *unless* the buyer and seller physically meet in person to conduct the transaction, which is in the eyes of the gun grabbers a huge "loophole".
