This legislation, known as "Jaime's Law," seeks to strengthen the background check system to prevent individuals prohibited by Federal and State law from acquiring ammunition. Its primary mechanism involves amending existing federal law to apply background check requirements to ammunition transfers, mirroring the process currently in place for firearm sales. Specifically, the bill makes it unlawful for unlicensed individuals to transfer ammunition to other unlicensed persons unless a licensed importer, manufacturer, or dealer first takes possession of the ammunition to conduct a background check. The licensee must then comply with all relevant requirements as if transferring ammunition from their own inventory. This measure aims to close a perceived loophole where ammunition could be transferred without the same scrutiny as firearms. However, the bill outlines several key exceptions to this new requirement. These include transfers to law enforcement or military personnel acting in their official capacity, and bona fide gifts or loans between specific family members such as spouses, parents and children, or siblings. Other exceptions cover transfers due to death, temporary transfers necessary to prevent imminent harm, and certain temporary transfers for activities like target shooting at a range, hunting, or when the transferor remains present. The legislation also mandates that licensed dealers provide notice of these prohibitions to unlicensed transferees and obtain certification. Importantly, the bill explicitly states that it does not authorize the establishment of a national firearms or ammunition registry, nor does it interfere with states' authority to enact their own laws on the subject. The provisions of this act are set to take effect 180 days after its enactment.
