What Are the Magazine Capacity Limits in Arizona?
Woody's answers are based on published federal and state law. Not legal advice. Consult a licensed attorney for your specific situation.
Arizona has no magazine capacity limits under state law. You can legally possess and use magazines of any capacity in Arizona, regardless of round count.
What This Means for You
Arizona's lack of magazine restrictions puts it among the most permissive states for builders who want to use standard or high-capacity magazines. This means you don't need to worry about modifying magazines or sourcing restricted-capacity versions. However, you should still be aware that federal locations within Arizona may have different rules, and traveling to other states with your magazines could create legal issues.
The Detail
Arizona state law does not impose any restrictions on magazine capacity for rifles, pistols, or shotguns. This means you can legally purchase, possess, and use magazines holding 10, 15, 20, 30, or more rounds without any special permits or registration requirements. The state takes a hands-off approach to magazine regulation, treating them as standard firearm accessories.
While Arizona state law is permissive, you need to consider federal property restrictions within the state. Military bases, federal buildings, and other federally controlled areas may have their own magazine capacity rules that override state law when you're on their property. Additionally, some local jurisdictions might attempt to regulate magazines, though state preemption laws generally prevent this.
The practical freedom Arizona provides extends to both factory magazines and aftermarket options. You can build rifles with standard 30-round magazines, use extended magazines for competition shooting, or carry pistols with full-capacity magazines for self-defense. This regulatory environment makes Arizona attractive for builders who don't want to deal with capacity restrictions that exist in states like California or New York.
Before assuming complete freedom, verify current laws with official Arizona state resources, as firearms regulations can change. Also research the laws of any state you plan to travel to with your magazines, since crossing state lines with high-capacity magazines can create legal problems in restrictive states.
Build Impact
You can plan your builds around standard-capacity magazines without worrying about Arizona state restrictions. This means you can use factory magazines as designed and don't need to source limited-capacity versions or modify existing magazines.
