Jaime's Law This bill establishes background check requirements for the sale and transfer of ammunition. Specifically, the bill prohibits a licensed importer, manufacturer, or dealer from transferring ammunition to an unlicensed individual prior to submitting a background check through the National Instant Criminal Background Check System. It also establishes penalties for violations. (Currently, background checks are required under these circumstances for the transfer of firearms, but not for ammunition.) Additionally, it prohibits an ammunition transfer between private parties (i.e., unlicensed individuals) unless a licensed importer, manufacturer, or dealer first takes possession of the ammunition to conduct a background check. However, this prohibition does not apply to certain ammunition transfers, such as a gift between spouses in good faith.
