It is unlawful to sell or give any firearm to any person

under 18 years of age, except a rifle or shotgun given by

a parent to a child for education, hunting, or sport. It is

unlawful for any parent or guardian to permit his or her

child to possess any firearm if aware of a substantial risk

that the child will use the weapon in a crime or if the

child has been adjudicated a delinquent or convicted as

an adult of any criminal offense.
