In 2019, Washington passed a law regulating ghost guns, referred to by Washington law as “undetectable” and “untraceable” firearms.1 The state defines undetectable and untraceable firearms as follows:
- “Undetectable firearm” means any firearm that is not as detectable as 3.7 ounces of 17-4 PH stainless steel by walk-through metal detectors or magnetometers commonly used at airports or any firearm where the barrel, the slide or cylinder, or the frame or receiver of the firearm would not generate an image that accurately depicts the shape of the part when examined by the types of X-ray machines commonly used at airports.
- “Untraceable firearm” means any firearm manufactured after July 1, 2019, that is not an antique firearm and that cannot be traced by law enforcement by means of a serial number affixed to the firearm by a federally licensed manufacturer or importer.2
It is illegal in the state to:
- Manufacture, own, buy, sell, loan, furnish, transport, or possess an undetectable firearm or any part designed and intended solely and exclusively for use in an undetectable firearm.3
- Assemble or repair any undetectable firearm.4
- Manufacture an untraceable firearm with the intent to sell it.5
- Assist a person who is prohibited from possessing firearms or who has signed a voluntary firearms waiver with manufacturing an undetectable or untraceable firearm.6
