Background Check Expansion Act

This bill requires background checks for most private firearm transfers between unlicensed individuals by mandating that such transfers occur through a licensed dealer. It directly affects unlicensed buyers and sellers of firearms who would otherwise transfer guns without checks, except for specific exceptions like family gifts, law enforcement transfers, temporary safety-related transfers, or transfers for hunting/shooting at designated locations. Key provisions include requiring licensed dealers to conduct background checks as if they were transferring the firearm themselves and adding a new requirement for written certification from the unlicensed transferee. The bill does not create a national gun registry and leaves state laws intact.
