I beg to differ on the purchase within Illinois. I live in Illinois and have been using my C&R to buy from local dealers and and at gun shows in Illinois from day one with no problem and no waiting period and no background check. It is an FFL and that is what is for.
You can beg all you want, but no matter what your experience has been, the law still requires the waiting period. Read the law in question, it's 720 ILCS 5/24-3:
(A) A person commits the offense of unlawful sale or delivery of firearms when he or she knowingly does any of the following:
(g) Delivers any firearm of a size which may be concealed upon the person, incidental to a sale, without withholding delivery of such firearm for at least 72 hours after application for its purchase has been made, or delivers any rifle, shotgun or other long gun, or a stun gun or taser, incidental to a sale, without withholding delivery of such rifle, shotgun or other long gun, or a stun gun or taser for at least 24 hours after application for its purchase has been made. However, this paragraph (g) does not apply to: (1) the sale of a firearm to a law enforcement officer if the seller of the firearm knows that the person to whom he or she is selling the firearm is a law enforcement officer or the sale of a firearm to a person who desires to purchase a firearm for use in promoting the public interest incident to his or her employment as a bank guard, armed truck guard, or other similar employment; (2) a mail order sale of a firearm to a nonresident of Illinois under which the firearm is mailed to a point outside the boundaries of Illinois; (3) the sale of a firearm to a nonresident of Illinois while at a firearm showing or display recognized by the Illinois Department of State Police; or (4) the sale of a firearm to a dealer licensed as a federal firearms dealer under Section 923 of the federal Gun Control Act of 1968 (18 U.S.C. 923). For purposes of this paragraph (g), "application" means when the buyer and seller reach an agreement to purchase a firearm.
Notice there's an exception for licensed
dealers, but an 03 FFL does not make you a licensed dealer. Unless there's case law somewhere that says licensed collectors qualify under that exception, your local dealers are breaking the law.
