What is an 80% Lower?

An 80% lower receiver is an unfinished and unserialized blank which requires some machining work from the end user to turn it into a 100% lower receiver, otherwise, what is legally considered as a firearm. 80 lowers are missing the trigger pocket and three holes that need to be milled and drilled out to be completed. Unless states have passed their own laws barring the possession or sales of 80% products; pending the ATF's updated decision from the most recent proposed rule 2021R-05 80% lowers are completely legal, not considered firearms and thus can be shipped straight to your front door. No FFL required. To explore the 80% lowers we have to offer, check out our multiple collections.

Key Gun Laws in Arizona

Other than laws regarding 80 lowers, these are the key gun laws you should be aware of if you reside or are traveling through Arizona.

Firearm Possession and Purchase Requirements

In the state of Arizona, anyone the age of 18 years or older is eligible to purchase a handgun or a long gun. There are no permits or any extra identification documents required to purchase handguns in Arizona other than a driver’s license. If one does have a CCW permit, stores will allow buyers to buy firearms without a background check (Dealer Record of Sale also known as 4473 form or “DROS”). While federal law requires federal firearm license holders (“FFL’s”:) to initiate background checks on buyers prior to the sale of a firearm, federal law also allows states to serve as their own “point of contact” and conduct their own background checks via state, federal records or databases, as well as the option to use the FBI’s National Instant Criminal Background Check System (“NICS”) database. Arizona is not a point of contact for the NICS and does not have any laws requiring firearms dealers to initiate the background check prior to transferring a firearm. However, Arizona still abides by the federal law and stores will still require buyers to do the DROS which uses the NICS and only takes about 15 minutes to complete unless there is a flag in the system.

Open and Concealed Carrying

Arizona is a Constitutional Carry state which means that residents no longer are required to have permits to conceal or open carry firearms. There are age requirements though; a person must be 21 years of age or over to conceal carry and to open carry a person must be at least 18 years old. Conceal carry weapons permits, or “CCW’s” are still offered by the state of Arizona and greatly encouraged for people to obtain. Arizona also offers non-resident CCW’s which are very valuable in increasing the amount of the southwestern regions’ and other states that honor and reciprocate your permit. Arizona is a “shall issue'' state. Be aware of the limits of open and conceal carrying by checking the state restrictions. To see which states’ concealed carry permits it honors check this reciprocity map here.

NFA Restrictions

There are no NFA weapons or items restrictions in Arizona and there are no assault weapon bans.

Magazine Capacity Restrictions

There are no magazine capacity restrictions in Arizona. Enjoy those drums and belt-fed box magazines! We carry plenty of standard capacity magazines like  this 30-round magazine from Lancer. Our favorite color is the translucent smoke one.

Mandatory Storage Requirements

There are no mandatory storage requirements for firearms in Arizona, however, you should still exercise caution and can be tried for negligently leaving your guns accessible to children. If you need some good ideas or best practices for storing your guns and gear here are 5 firearm storage options.


Arizona does have a Castle Doctrine law in place and the state does allow you to “Stand Your Ground.”

Ammunition Purchase

No state permit or background check is required to purchase any ammunition in Arizona nor are any records of ammo purchases kept. Arizona does not prohibit armor-piercing rounds or other “unreasonably dangerous ammunition.” It is a felony to sell or give ammunition to a minor without parental consent. Any handgun ammo and online purchases of ammo shipped to Arizona require buyers to be at least 21 years old.
