1 AN ACT to amend 939.6195 (1) (a) 1. and 941.291 (1) (b); and to create 941.293
2 of the statutes; relating to: prohibition against undetectable firearms,
3 possessing a frame or receiver of a firearm without a serial number, and
4 providing a penalty.
Analysis by the 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 the 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 the prohibition is guilty
of a Class I felony.
