“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; proving a penalty; and providing for an effective date,” the bill states.

“Any official, agent or employee of the United States government who enforces or attempts to enforce any act, order, law, statute, rule or regulation of the United States government upon a personal firearm, a firearm accessory or ammunition that is owned or manufactured commercially or privately in Wyoming and that remains exclusively within the borders of Wyoming shall be guilty of a felony,” the proposed legislation adds.
