HB 2307 exempts certain Arizona manufactured firearms, firearms accessories and ammunition from federal interstate commerce laws and regulations.


Article I, Section 8, Clause 3 of the Constitution of the United States grants Congress the power to “regulate commerce with foreign nations, and among the several states, and with Indian tribes.”

In 2009, the state of Montana enacted the “Montana Firearms Freedom Act” (MFFA), which contains provisions relating to exemptions for certain Montana manufactured firearms, firearms accessories and ammunition.  In an open letter from the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) addressed to all Montana federal firearms licensees dated July 16, 2009, BATFE stated that federal law, to include all provisions of the Gun Control Act and National Firearms Act, relating to manufacturing licenses and registration of firearms, respectively, supersedes MFFA.  Subsequently, the Montana Shooting Sports Association, Second Amendment Foundation, and Mr. Gary Marbut have filed a joint complaint in the United States District Court for the District of Montana, Missoula Division, which contests the Federal government’s regulatory authority over the provisions within MFFA.

Ø      Is commercially or privately manufactured in Arizona from basic materials, and that can be manufactured without importing significant parts from out-of-state; and
