To require serialization of firearms produced through additive manufacturing and of unserialized firearms possessed by federally licensed firearms dealers and gunsmiths, to establish penalties for violations, and for other purposes

**Who it affects:** - People who make firearms using 3D printers or similar technology - Federally licensed firearms dealers (gun stores) - Licensed gunsmiths - Anyone who violates the new serialization requirements **What would change:** - All 3D-printed firearms would need to have serial numbers - Licensed dealers and gunsmiths would need to add serial numbers to any unserialized firearms in their possession - New criminal penalties would apply to those who don't follow these rules - Law enforcement would have better ability to trace these previously hard-to-track firearms The bill is currently being reviewed by a House committee and has not been voted on by Congress.
