What this bill does

Plain-language analysis by the nonpartisan Legislative Reference Bureau

This bill prohibits the manufacture, transportation, sale, possession, and carrying of firearms that cannot be detected by metal detectors or airport x-ray machines or scanners. Federal law currently has a comparable prohibition; under this bill, the person would violate state law as well. A person who violates the state prohibition is guilty of a Class G felony.

This bill also prohibits the sale, posting, provision, or possession of plans for manufacturing an undetectable firearm. A person who violates this prohibition is guilty of a Class H felony.

Finally, the bill prohibits the possession of a frame or a receiver of a firearm that is not marked with a serial number. A person who violates this prohibition is guilty of a Class I felony.

Because this bill creates a new crime or revises a penalty for an existing crime, the Joint Review Committee on Criminal Penalties may be requested to prepare a report.
