Delaware lawmakers are aiming to crackdown on untraceable firearms and their components without serial numbers.
Lawmakers want to expand the definition of a firearm to include gun components that are 80 percent finished meaning that they need machine tools.
The WBOC reports that federal government allows arms built by someone without a registered serial number only for personal use and are not to be transferred to someone else.
The Delaware legislation also makes it illegal to possess make or import untraceable firearms in the state.
The expanded state definition includes those weapons made with a 3D printer.
