Key Notes

Wyoming Firearms Freedom Act (2010) restricts federal NFA enforcement for in-state manufactured firearms. Firearms must be stamped "Made in Wyoming." Federal enforcement still possible.

  • •Permitless (21+) — Adults 21 and older can carry concealed without a permit. Wyoming was one of the earlier constitutional carry states.
  • •Unrestricted (in-state) NFA — Wyoming passed the Firearms Freedom Act (2010) claiming to exempt in-state manufactured NFA items from federal regulation. In practice, federal ATF enforcement still applies and a tax stamp is still required.
  • •Yes, no permit (Open Carry) — Open carry of handguns and long guns is legal without any permit.
  • •State Preemption: Yes — Local governments cannot enact their own firearm regulations.
  • •No Background Check (Private) — Private sales between individuals do not require a background check.
  • •Permits for Reciprocity — While not required for in-state carry, Wyoming issues concealed firearms permits for reciprocity with other states.
