From Article linked above (I added the bold to the text below as well as condensed it and added the hyphen in front for clarity):
House Bill 5855 from state Rep. Bob Morgan, D-Deerfield, is being debated in a House committee this week. If passed, the measure would prohibit anyone under 21 from getting a Firearm Owner’s Identification Card unless they are enlisted in the armed services.
The bill would also prohibit the sale and possession of any magazines that hold more than 10 rounds. Among other provisions include extending gun-related restraining orders from six months to a year.
While the legislation says "assault weapon" does not include any gun that is bolt, pump, lever or slide action, is unserviceable or made inoperable, antique, uses rimfire ammunition or cartridges, “or has been excluded as an assault weapon in a Department of Natural Resources rule,” it does list around 100 different types of guns and brands as assault weapons.
Anyone in possession of an “assault weapon” would have 300 days from the bill’s enactment to register the firearm with Illinois State Police. Below is the list of guns listed as "assault weapons" in the legislation.
