As I understand the original bill(Before Quinn replaced the entire bill with his AWB) clarified some legalese so it is CLEAR that someone from Illinois can buy ammo online from a seller outside Illinois but also from seller INSIDE Illinois. I believe the way its worded now "technically' you can only buy ammo online/through the mail from an out of state seller. Not that it stops anyone, I buy ammo from a dealer in Southern Illinois all the time..
This AWB is basically word for word an AWB that a Democratic rep from Chicago has been pushing for a while but that did not have anywhere near the votes to even come up for a vote this legislative session. On the one hand the likelihood of this passing is slim...on the other this is Illinois, god knows what kind of back room deals are going on right, god knows who has dirt on who so anything CAN happen in the world of Chicago style politics.
