While no NICS background checks are required before renting a gun to an individual, retailers are still prohibited from renting a firearm to any person whom they believe is prohibited from receiving or possessing a firearm by law. The same prohibitions listed under 18 USC 922(d) and 922(g) and on the front of ATF Form 4473 (see items 11b-l2) apply to persons renting firearms for use on your premises.

You may be wondering how you and your staff can identify the difference between prohibited and non-prohibited persons when it comes to firearm rentals; it is certainly easier to ascertain this difference when selling a gun. As you know, a sale requires both a completed ATF Form 4473 and an approved NICS background check. However, since a firearm rental is not considered a transfer, a retailer cannot access NICS to conduct a NICS check. As a result, some retailers develop their own rental form questionnaires. These questionnaires use language from questions in items 11b through 12 from the Form 4473. Federally licensed retailers can also ask the same information required by items 13 though 15 and item 20c of the Form 4473 on their personally created rental form. It is a good idea to have the person renting the firearm sign the form attesting to its accuracy.
It should be noted that the actual ATF F 4473 should not be used for firearm rentals. Remember, you must be reasonably sure that the person renting a firearm from you, for use on your premises, is not prohibited by law from receiving or possessing the firearm. Federal law and regulation do not spell out the specifics of how to make this determination, but the responsibility of not knowingly renting firearms to prohibited persons sits squarely on your shoulders as a licensed firearms retailer.
