Washington State Passes HB 2320 to Combat 3D Printed Ghost Guns

Washington State has taken a significant step in regulating 3D-printed firearms. On March 17, 2026, the state legislature passed HB 2320, a bill designed to strengthen the state ghost gun law and address the growing threat of untraceable, 3D-printed firearms.

Closing the Digital Loophole

Ghost guns are unserialized, untraceable firearms that can be manufactured at home without a background check. This allows people prohibited from possessing guns to bypass Washington gun safety laws. HB 2320 modernizes Washington law to keep pace with rapidly evolving technology.

Our laws must be as sophisticated as the technology used to circumvent them and HB 2320 meets that challenge by closing the dangerous loopholes created by 3D-printing.

What HB 2320 Does

The bill strengthens the state existing ghost gun statute by addressing digital gun blueprints, making it clear that using 3D printers to manufacture firearms is a crime in Washington, and strengthening safeguards against the growing use of 3D printing to manufacture firearms outside the legal system.

The bill now heads to Governor Bob Ferguson desk to be signed into law.
