    (A) A person commits the offense of unlawful sale or delivery of firearms when he or she knowingly does any of the following:
        (a) Sells or gives any firearm of a size which may be
    
concealed upon the person to any person under 18 years of age.

been a patient in a mental institution within the past 5 years. In this subsection (e):
            "Mental institution" means any hospital,
        
institution, clinic, evaluation facility, mental health center, or part thereof, which is used primarily for the care or treatment of persons with mental illness.
            "Patient in a mental institution" means the

        (f) Sells or gives any firearms to any person who is
    
a person with an intellectual disability.
        (g) Delivers any firearm, incidental to a sale,
    
without withholding delivery of the firearm for at least 72 hours after application for its purchase has been made, or delivers a stun gun or taser, incidental to a sale, without withholding delivery of the 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 from a federally licensed firearms dealer to a nonresident of Illinois under which the firearm is mailed to a federally licensed firearms dealer outside the boundaries of Illinois; (3) (blank); (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); or (5) the transfer or sale of any rifle, shotgun, or other long gun to a resident registered competitor or attendee or non-resident registered competitor or attendee by any dealer licensed as a federal firearms dealer under Section 923 of the federal Gun Control Act of 1968 at competitive shooting events held at the World Shooting Complex sanctioned by a national governing body. For purposes of transfers or sales under subparagraph (5) of this paragraph (g), the Department of Natural Resources shall give notice to the Illinois State Police at least 30 calendar days prior to any competitive shooting events at the World Shooting Complex sanctioned by a national governing body. The notification shall be made on a form prescribed by the Illinois State Police. The sanctioning body shall provide a list of all registered competitors and attendees at least 24 hours before the events to the Illinois State Police. Any changes to the list of registered competitors and attendees shall be forwarded to the Illinois State Police as soon as practicable. The Illinois State Police must destroy the list of registered competitors and attendees no later than 30 days after the date of the event. Nothing in this paragraph (g) relieves a federally licensed firearm dealer from the requirements of conducting a NICS background check through the Illinois Point of Contact under 18 U.S.C. 922(t). For purposes of this paragraph (g), "application" means when the buyer and seller reach an agreement to purchase a firearm. For purposes of this paragraph (g), "national governing body" means a group of persons who adopt rules and formulate policy on behalf of a national firearm sporting organization.
        (h) While holding any license as a dealer, importer,
    
manufacturer or pawnbroker under the federal Gun Control Act of 1968, manufactures, sells or delivers to any unlicensed person a handgun having a barrel, slide, frame or receiver which is a die casting of zinc alloy or any other nonhomogeneous metal which will melt or deform at a temperature of less than 800 degrees Fahrenheit. For purposes of this paragraph, (1) "firearm" is defined as in the Firearm Owners Identification Card Act; and (2) "handgun" is defined as a firearm designed to be held and fired by the use of a single hand, and includes a combination of parts from which such a firearm can be assembled.
        (i) Sells or gives a firearm of any size to any
    
person under 18 years of age who does not possess a valid Firearm Owner's Identification Card.
        (j) Sells or gives a firearm while engaged in the
    
business of selling firearms at wholesale or retail without being licensed as a federal firearms dealer under Section 923 of the federal Gun Control Act of 1968 (18 U.S.C. 923). In this paragraph (j):
        A person "engaged in the business" means a person who
    
devotes time, attention, and labor to engaging in the activity as a regular course of trade or business with the principal objective of livelihood and profit, but does not include a person who makes occasional repairs of firearms or who occasionally fits special barrels, stocks, or trigger mechanisms to firearms.
        "With the principal objective of livelihood and
    
profit" means that the intent underlying the sale or disposition of firearms is predominantly one of obtaining livelihood and pecuniary gain, as opposed to other intents, such as improving or liquidating a personal firearms collection; however, proof of profit shall not be required as to a person who engages in the regular and repetitive purchase and disposition of firearms for criminal purposes or terrorism.
        (k) Sells or transfers ownership of a firearm to a
    
person who does not display to the seller or transferor of the firearm either: (1) a currently valid Firearm Owner's Identification Card that has previously been issued in the transferee's name by the Illinois State Police under the provisions of the Firearm Owners Identification Card Act; or (2) a currently valid license to carry a concealed firearm that has previously been issued in the transferee's name by the Illinois State Police under the Firearm Concealed Carry Act. This paragraph (k) does not apply to the transfer of a firearm to a person who is exempt from the requirement of possessing a Firearm Owner's Identification Card under Section 2 of the Firearm Owners Identification Card Act. For the purposes of this Section, a currently valid Firearm Owner's Identification Card or license to carry a concealed firearm means receipt of an approval number issued in accordance with subsection (a-10) of Section 3 or Section 3.1 of the Firearm Owners Identification Card Act.
            (1) In addition to the other requirements of this
        
paragraph (k), all persons who are not federally licensed firearms dealers must also have complied with subsection (a-10) of Section 3 of the Firearm Owners Identification Card Act by determining the validity of a purchaser's Firearm Owner's Identification Card.
            (2) All sellers or transferors who have complied
        
with the requirements of subparagraph (1) of this paragraph (k) shall not be liable for damages in any civil action arising from the use or misuse by the transferee of the firearm transferred, except for willful or wanton misconduct on the part of the seller or transferor.
        (l) Not being entitled to the possession of a
    
firearm, delivers the firearm, knowing it to have been stolen or converted. It may be inferred that a person who possesses a firearm with knowledge that its serial number has been removed or altered has knowledge that the firearm is stolen or converted.
    (B) Paragraph (h) of subsection (A) does not include firearms sold within 6 months after enactment of Public Act 78-355 (approved August 21, 1973, effective October 1, 1973), nor is any firearm legally owned or possessed by any citizen or purchased by any citizen within 6 months after the enactment of Public Act 78-355 subject to confiscation or seizure under the provisions of that Public Act. Nothing in Public Act 78-355 shall be construed to prohibit the gift or trade of any firearm if that firearm was legally held or acquired within 6 months after the enactment of that Public Act.
