GOA had this to say:
Just when it seems likely that Congress may sunset the
unconstitutional federal ban on new semiautomatic firearms, anti-gun
members of the Illinois Senate in Springfield are pushing
legislation that would make Washington, D.C., look pro-gun by
comparison.
Illinois Senate Bill 2561, sponsored by anti-gun zealot Senator
Antonio Munoz, would outlaw virtually all semiautomatic firearms --
whether or not covered by the federal ban -- and would require that
all banned guns be immediately relinquished.
What would be banned under the Illinois law? Under section 5 of the
bill, banned firearms would include:
* any semiautomatic rifle with a detachable magazine of any size
and any one of five additional characteristics;
* any semiautomatic pistol with a detachable magazine of any size
and any one of five additional characteristics;
* any semiautomatic shotgun with a folding or telescoping stock, a
protruding pistol grip, a fixed magazine capacity exceeding five
rounds, or an ability to accept a detachable magazine.
After 90 days, possession of all of these firearms would be
outlawed. If you fail to turn in, remove, or incapacitate your
semiautomatic firearm, the police could come and seize your firearm
-- at gunpoint, in the presence of your family -- and you would be
guilty of a Class 3 felony and subject to imprisonment.
There is also some confusing language present in the text "any firearm .50 caliber or larger" as before that would knock out most muzzleloaders and shotguns, depending on how it is interpreted.
It is unconstitutional under Illinois law, as the state cannot determine the destruction or forfeiture of property without compensation-- and there is no grandfather clause present. It does nothing to address crime, as always-- guns can't commit crime on their own.
