Answer: Gun laws are found under the Weapons and Explosive chapter under title 13 of the Arizona Revised Statutes.
13-3109. Sale or gift of firearm to minor; classification
A. Except as provided in subsection C of this section, a person who sells or gives to a minor, without written consent of the minor's parent or legal guardian, a firearm, ammunition or a toy pistol by which dangerous and explosive substances may be discharged is guilty of a class 6 felony.
B. Nothing in this section shall be construed to require reporting sales of firearms, nor shall registration of firearms or firearms sales be required.
C. The temporary transfer of firearms and ammunition by firearms safety instructors, hunter safety instructors, competition coaches or their assistants shall be allowed if the minor's parent or guardian has given consent for the minor to participate in activities such as firearms or hunting safety courses, firearms competition or training. With the consent of the minor's parent or guardian, the temporary transfer of firearms and ammunition by an adult accompanying minors engaged in hunting or formal or informal target shooting activities shall be allowed for those purposes.
What this means to you:
It is illegal for a person under the age of 18 to buy a gun of any type in Arizona. A minor who is given permission by a parent or guardian may use a gun for hunting or target practice while under the supervision of an adult.
