Within days of opening its 51st Legislature, Arizona state lawmakers have begun considering HB 2291--a bill which declares any federal attempt to "ban or restrict ownership of a semi-automatic firearm... unenforceable" in the state.
Moreover, the bill also lists as "unenforceable" any federal ban on magazines for such weapons and categorizes any requirement for firearm registration as a non-starter as well.
As Wyoming, Texas, and Oklahoma have done, AZ H.B. 2291 threatens felony charges for federal gun grabbers who seek to enforce these measures.
The legislation focuses specifically on guns which are made and sold within the state of Arizona, therefore never falling under the purview of rules and regulations regarding interstate commerce. This means the Arizona statute would cover weapons made by Ruger Firearms (Prescott, AZ) and Spirit Arms (Scottsdale, AZ), among many others.
