It sounds like a convenient set up to me..
I can see the headlines now.. "See how easy it is to get an assault rifle! Etc. etc..."
Once I thought about it for 10 seconds, that's what came to mind.. If Schumer isn't talking about this within the next two months, (just because he's not in session right now), I will be surprised...
One more observation.. If the thing is an assault rifle, the legislatures/courts are gonna have to figure out something new to call the crime of hitting somebody with a fist..
