Requires universal background checks for all sales or transfers of firearms

This bill requires background checks for all firearm sales and transfers between private individuals, not just those conducted by licensed dealers. It mandates that anyone selling a gun must arrange for a background check through a licensed dealer or law enforcement agency and cannot complete the sale until the central repository approves the transfer. The law includes specific exceptions for transfers within immediate families, gunsmith repairs, temporary use at shooting ranges or while hunting, and other official or emergency situations. Violations of these requirements are classified as class B misdemeanors, and licensed dealers found in violation must report the incident to state and federal authorities.
