Short answer: It is a misdemeanor to sell, directly or indirectly, any pistol, revolver or gun (or dirk, bowie knife or dagger) to a minor under eighteen (18) without the written consent of the minor's parent or guardian; Idaho Code §§ 18-3302A, 18-3308, 18-3302F, 18-3302G

Age to buy a gunIt is a misdemeanor to sell, directly or indirectly, any pistol, revolver or gun (or dirk, bowie knife or dagger) to a minor under eighteen (18) without the written consent of the minor's parent or guardian; selling or giving any firearm to a minor under sixteen (16) without written parental consent is also a misdemeanor. A person under eighteen (18) may not possess a handgun (except under listed exceptions such as hunting, ranges and safety courses), and providing a handgun to a minor in violation of that rule is a misdemeanor. The same rules apply to private sellers; state law sets no higher purchase age.

Background checks and private salesIdaho has no state law that requires a background check, permit or license for private (non-dealer) firearm sales, and Idaho has no permit-to-purchase. The state occupies the whole field of firearms regulation, so cities and counties may not regulate the sale, acquisition or transfer of firearms. A person 21 or older who presents a valid Idaho concealed weapons license is exempt from the records check at the time of purchase from a federally licensed dealer (a temporary emergency license does not qualify).
