So, you have to have a coupon for the gun? The title says possession would be illegal- with out the paper?
I think the biggest thing is that 10 round magazines hits rifles, but it also hits handguns. That always gets overlooked.
Basically, the law makes a criminal out of everyone that owns a semi-auto handgun. And since these are always sold as AWB and bump stock bans, most people don't realize it means them too.
ETA: I really think that the issue of handguns and magazines by making thousands of people who don't own EBRs into criminals might resonate.
