AB321,1,4

An Act
to amend
939.6195 (1) (a) 1. and 941.291 (1) (b);
to create
941.293 of
2
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 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.
The people of the state of Wisconsin, represented in senate and assembly, do enact as follows:
