Bill Overview

Analyzed Economic Effects

4 provisions identified: 0 benefits, 3 costs, 1 mixed.

Ban on untraceable guns and build files

The law bans making, selling, or possessing untraceable guns. It also bans dealing in unfinished frames or receivers made after March 10, 2023, unless they have a serial number from an authorized federal dealer or are held by law enforcement or a federal licensee. Sharing or possessing digital gun‑making files is restricted to federal firearms manufacturers and dealers licensed only for repair. Making frames or receivers with 3D printers or CNC machines is limited to those licensees. "Distribute" includes online orders and deliveries into Washington. A first offense is a $500 civil infraction; repeats can be misdemeanors or gross misdemeanors, and three or more items at once is a gross misdemeanor. Each item counts separately.

Helping banned buyers make guns is illegal

You cannot knowingly or recklessly help someone who is barred from having guns make or assemble an undetectable or untraceable gun. Sharing digital manufacturing code that helps them is also banned. Not doing a required background check is evidence of recklessness. A first offense is a gross misdemeanor; later offenses are a class C felony. Each gun counts as a separate offense.

Machine guns, bump stocks, short‑barrel weapons banned

The law makes it illegal to make, own, buy, sell, or possess machine guns, bump‑fire stocks, undetectable guns, and short‑barreled shotguns or rifles. It also bans making parts designed only for those items. "Undetectable" means a gun that fails airport‑style metal detector or X‑ray standards (at least as detectable as 3.7 ounces of stainless steel). Violations are class C felonies. Limited exemptions apply for peace officers, armed forces, and certain federally licensed production for military, law enforcement, or export.

Definitions update ends June 30, 2027

Section 2 applies until June 30, 2027. On that date, Section 3 takes effect and replaces Section 2. This timing sets which definitions and related rules apply before and after June 30, 2027.
