Legal Disclaimer: The information in this blog is not legal advice. We are not lawyers.

Legal changes can often be difficult to uncover, unpack, and publish in real-time. Therefore, while we try our best to provide timely information, be aware that what you’re reading below may change (or already has changed).

Do not rely solely on the information provided by us or on this website to ensure compliance with your purchase decisions. To ensure that you, the buyer, are acting in accordance with all federal, state laws and local ordinances, please do your own research and consult an attorney if necessary.

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% lower receivers we have to offer, check out our multiple collections.

Are 80 Lowers Legal In Tennessee?

As of this guide’s initial publish date, 80% lower receivers and frames are not considered as firearms by the ATF and are legal to ship directly to buyers residing in the state of Tennessee.

Do I Need to Serialize My 80 Lower in Tennessee?

If you build out your own firearms starting with 80 lowers in Tennessee you do not need to serialize the lower receiver or frame as there are currently no laws requiring citizens to do so. Should you wish to serialize your lower receiver you certainly can if necessary through our engraving services for 80 lowers.

Key Gun Laws in Tennessee

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

Firearm Possession and Purchase Requirements

To purchase a long gun in Tennessee buyers must be at least 18 years old. To purchase a handgun in Tennessee buyers must be at least 21 years old. No extra permits are needed to purchase handguns or long guns in Tennessee nor is extra registration necessary. Tennessee’s minimum age for possession of handguns is 18 years old and there is no minimum age restriction for possession of long guns. In the event a minor is in possession of a handgun the normal exemption applies when minors have prior written consent from their parents or guardian or if they are in 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. Tennessee is a partial point of contact for the NICS and as a result, dealers must conduct their background checks by going through the “TBI” or Tennessee Bureau of Investigation.

Open and Concealed Carrying

Before you get your honky tonk on, make sure you know Tennessee's firearm carrying laws.Tennessee is a “shall-issue” and permitless state for concealed carrying. Permits are offered to Tennessee residents in two forms: a “HCP” and “EHCP” or handgun carry permit/enhanced. Applicants for the HCP only need to complete a 90 minute online course. The Enhanced HCP requires completion of a state-approved 8 hour class which allows the permit holder to carry a gun more openly or concealed to more places. 

Any concealed carrier must be at least 21 years or older unless they are active duty members of the military who have completed basic training. Non-residents can apply for HCP only if they work in the state on a regular basis and hold a valid permit from their home state. For more details on their concealed carrying policies see Tennessee’s reciprocity map here.

NFA Restrictions

Tennessee is a fantastic state to own and have NFA weapons and related items. Might be why T.Rex Arms is based there as the state does not have an “assault weapons” ban nor any other extra restrictions not already enforced by the ATF.

Magazine Capacity Restrictions

There are no magazine capacity restrictions in Tennessee. Enjoy those sticks, 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

Tennessee does not require firearm owners to lock their firearms in any way, shape or form. I.e. “mandatory storage” or “safe storage requirements.” However, you should still exercise caution because you 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.


Tennessee is a castle doctrine state and has a stand your ground law in place as well which means that when justified but the laws in Tennessee do not require residents to have a duty to retreat before exercising the use of force or violence in defense of themselves or others.

Ammunition Purchase

Tennessee does not require a license for the purchase, possession or sale of ammo. Basically all ammunition is unrestricted in Tennessee. Online ammo purchases require buyers to be at least 21 years old but can be delivered straight to your front door.
