H.B. 104 is "AN ACT relating to firearms; providing that any federal law which attempts to ban a semi-automatic firearm or to limit the size of a magazine of a firearm or other limitation on firearms in this state shall be unenforceable in Wyoming; providing a penalty; and providing for an effective date."
From the bill:
(d) Any federal law, rule, regulation or order created or effective on or after January 1, 2013 shall be unenforceable within the borders of Wyoming if the law, rule, regulation or order attempts to:
(i) Ban or restrict ownership of a semi-automatic firearm or any magazine of a firearm; or
(ii) Require any firearm, magazine or other firearm accessory to be registered in any manner.This bill amends Wyoming Statute 6-8-405. Offenses and penalties; defense of Wyoming citizens, also known as the "Firearms Freedom Act". This is the infamous Wyoming law that makes it a crime to enforce Federal firearms law against Wyoming residents who own firearms that are manufactured in Wyoming. The Firearms Freedom Act was signed in to law and is now in the Ninth Circuit.
So, right now Wyoming law states that a Wyoming firearm manufacturer can produce fully automatic firearms and sell them to Wyoming residents without filing paperwork with the ATF. Problem is, until the courts clear this up, owning an unregistered fully automatic firearm will still most likely get you tossed in prison for a long time. On a positive note, your name will end up as a plaintiff when the case goes to the Supreme Court.
