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 percent lowers we have to offer, check out our multiple collections.

Key Gun Laws in Oklahoma

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

Firearm Possession and Purchase Requirements

To purchase a long gun in Oklahoma buyers must be at least 18 years old. To purchase a handgun in Oklahoma buyers must be at least 21 years old. No extra permits are needed to purchase handguns or long guns in Oklahoma nor is extra registration necessary. Oklahoma’s minimum age for possession of firearms is 18 years old but whether they are using a long gun or handgun, the normal exemption applies when minor are in the direct supervision or presence of their parents, guardian or when attending a hunter’s or firearms safety course, using the gun for target practice or recreational shooting at an established range, involved in an organized competition, hunting or trapping with a valid license, traveling to and from these events, or at their own residence with permission and supervision of a parents or a legal guardian.

All firearm purchases and transfers require a background check not including private party transfers (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. Oklahoma is not a point of contact for the NICS and as a result, dealers must conduct their background checks by going through the FBI’s NICS directly. Per the Brady Act, any ccw license holder would be exempt from needing a background check when buying a gun at an FFL dealer.

Open and Concealed Carrying

Oklahoma is a “shall-issue” and permitless carry state for ccw’s and offers them to residents in the form of a “SDAL” or Self-Defense Act Licenses. These licenses are issued at the county level by local Sheriff’s offices. Open carrying is legal for anyone who can legally own/possess a firearm and is 21 years of age or older. Applicants can apply for SDAL’s as long as they are at least 21 years of age or 18 years if they are an active duty service member of the military. SDAL’s do limit handgun calibers to .45 ACP being the highest allowed for use under the license. Oklahoma does not issue non-resident permits. For more details on the state’s concealed carrying policies check out Oklahoma’s reciprocity map here.

NFA Restrictions

There are no NFA weapons or items restrictions in Oklahoma and there are no assault weapon bans as Machine guns are allowed in the state of Oklahoma and is a very NFA-item friendly place.

Magazine Capacity Restrictions

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

Mandatory Storage Requirements

There are no mandatory storage requirements for firearms in Oklahoma, 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 ways to store your firearms at home.


Oklahoma is a castle doctrine state and is also a stand your ground state which means there is no duty to retreat before using force in self-defense or defense of another.

Ammunition Purchase

The only type of ammunition that is prohibited in Oklahoma is ammo that’s advertised or marketed as a “restricted bullet.” Which is just another way to describe a certain type of armor piercing rounds that have a core of less than 60% lead and has fluorocarbon coating which allows it to fly at a higher velocity. No license is required for the purchase, possession or sale of ammo so long as long gun ammo buyers are at least 18 years old and handgun ammo buyers are at least 21 years old.
