Sponsor: Representative Diaz, LD 19
Committee on Judiciary
Overview
Exempts personal firearms, firearm accessories and ammunition that are modified in Arizona and
remain in Arizona from federal laws and regulations enacted pursuant to Congress's authority to
regulate interstate commerce.
History
A.R.S. § 13-3114, enacted by Laws 2010, Chapter 18, § 1, exempts certain Arizona manufactured
firearms, firearm accessories and ammunition from federal laws and regulations enacted under
color of Congress's authority to regulate interstate commerce. Along with this statute's passage,
Laws 2010, Chapter 18, § 2, made several legislative findings regarding U.S. Const. amends. II,
IX and X; Ariz. Const. art. II, § 26; and the power of the states to regulate intrastate commerce.
Specifically, beginning on October 1, 2010, A.R.S. § 13-3114 exempts from federal law or
regulation, including registration, any personal firearm, firearm accessory or ammunition that:
1) Is commercially or privately manufactured in Arizona from basic materials, and that can
be manufactured without importing significant parts from out-of-state; and
2) Remains within the state of Arizona.
The statute further 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. Any firearm that is
manufactured and sold in Arizona pursuant to this statute must have the words made in Arizona
clearly stamped on a central metallic part such as the receiver or frame. This exemption does not
apply to any firearm that:
1) Cannot be carried and used by one person;
2) Has a bore diameter of more than one and one-half inches and that uses smokeless
powder as a propellent; and
3) Discharges two or more projectiles with one activation of the trigger or firing device.
The statute also defines firearm accessory, general or insignificant part and manufactured (A.R.S.
§ 13-3114).
