HB 2320 Washington House · 2025-2026 Regular Session

Concerning the regulation of firearm manufacturing.

HB 2320 regulates firearm manufacturing using 3D printers, CNC mills, or digital code by requiring manufacturers to register these methods with the state. It directly affects individuals or entities producing firearms through digital means, including those creating undetectable or untraceable weapons. The bill amends Washington’s firearm laws to mandate registration of such manufacturing processes and explicitly targets unlicensed producers who might bypass background checks. This policy change aims to address public safety concerns by making digital firearm production subject to state oversight.

MINOR

The bill was amended to clarify that digital firearm manufacturing code and unfinished frames can only be sold or possessed for manufacturing purposes by federal firearms manufacturers or federal firearms dealers licensed specifically for repairing existing firearms. This change removes the previous requirement for a general federal firearms manufacturing license, thereby expanding the pool of eligible recipients to include repair shops. Additionally, the penalties for violating these new rules were increased for repeat offenders and for those attempting to manufacture multiple untraceable firearms at once.

Scope change

The scope of eligibility to legally handle digital firearm manufacturing code and unfinished frames was expanded to include federal firearms dealers licensed solely for repairing existing firearms, whereas previously only general federal firearms manufacturers were explicitly covered.

ELIGIBILITY

Updated rules for selling and possessing digital firearm manufacturing code and unfinished frames to allow transactions with federal firearms dealers licensed for repairing existing firearms, in addition to federal firearms manufacturers.

ENFORCEMENT

Strengthened penalties by adding specific provisions for repeat violations and for manufacturing or possessing multiple untraceable firearms simultaneously.

REQUIREMENT

Revised the licensing requirements for manufacturing frames or receivers to explicitly include federal firearms dealers licensed for repairing existing firearms.
