Generally, a person may only acquire a firearm within the person’s own state. Exceptions include the acquisition pursuant to a lawful bequest, or an over-the-counter acquisition of a rifle or shotgun from a licensee where the transaction is allowed by the purchaser’s state of residence and the licensee’s state of business. A person may borrow or rent a firearm in any state for temporary use for lawful sporting purposes.
