Thank God they overreached. Every pistol and rifle with a detachable magazine? Hard to imagine this passing muster...
It doesn't say that at all. It limits the number of rounds in any such to ten. And lists features that in addition to the ten rd mag would make it an 'assault weapon'.
This is essentially the old AWB vis a vis weapon description.
The over-reach is making possession of more than two firearms a felony.
It will go nowhere.
