Our Gov. Jan Brewer signed this one into effect.
HB 2307 - Arizona manufactured firearms; regulation
It will be curious to see how this plays out in the courts.
" Exempts from federal regulation, any imported firearms accessory, generic or insignificant part or basic materials that are incorporated into, attached to, or used in conjunction with a firearm, firearm accessory, or ammunition manufactured in Arizona."
Does this mean that you could use a silencer without paying the federal tax? No more ear plugs?
