Hi Jason and welcome. Unfortunately, no Sir due to the detachable magazine.
"Assault weapon" means any of the following:
A. A semiautomatic rifle that has the capacity to accept a detachable magazine or that may be
readilymodified to accept a detachable magazine, if the firearm has one or more of the
following:
i. a pistol grip or thumbhole stock;
ii. any feature capable of functioning as a protruding grip that can be held by the
non-trigger hand;
iii. a folding, telescoping, thumbhole, or detachable stock, or a stock that is otherwise
foldable or adjustable in a manner that operates to reduce the length, size, or any other
dimension, or otherwise enhances the concealability of, the weapon;
iv. a flash suppressor;
v. a grenedae launcher;
vi. a shroud attached to the barrel or that partially or completely encircles the barrel,
allowing the bearer to hold the firearm with the non-trigger hand without being burned,
but excluding a slide that encloses the barrel.

Hi Jason, no sir, the M1 Carbine is not Illinois legal.
