Full text of RCW 9.41.140
Statutory text current through the 2026 Regular Session. This publication reproduces the official text of the Revised Code of Washington from the Code Reviser's published files; it is not the official statutes of the State of Washington.
No person may change, alter, remove, or obliterate the name of the maker, model, manufacturer's number, or other mark of identification on any firearm. Possession of any firearm upon which any such mark shall have been changed, altered, removed, or obliterated, shall be prima facie evidence that the possessor has changed, altered, removed, or obliterated the same. This section shall not apply to replacement barrels in old firearms, which barrels are produced by current manufacturers and therefor do not have the markings on the barrels of the original manufacturers who are no longer in business. This section also shall not apply if the changes do not make the firearm illegal for the person to possess under state or federal law.
