A loop hole I may have realized while at work today, let me see what you all think. (I will get quotes when I have some free time).
According to the new law, the rifle must be a complete rifle when referring to multiple caliber rifle receivers, like the Fab-10. Right?
Also, they frequently state that a 'firearm' need not be assembled to be considered a firearm. I believe there is actually a quote that says the receiver is the firearm.
Wouldn't that mean that you would just need a fully functional firearm, aka receiver, in order for it be legal? Upper or no upper, the firearm, as it is seen by the DOJ, is a complete and functional firearm as per the law. While we may understand what they meant to say, in a legal sense, they may have created a loop hole for those with AR-15 style lowers who didn't have the cash to buy uppers.
