Getting Started

What is an 80% lower receiver?

An 80% lower receiver is considered a firearm blank. It roughly resembles a firearm receiver, but it is not functional, so it is not defined as a gun under federal law. You, the buyer and builder, get to turn the firearm blank into a firearm by definition.

This guide provides more detail: What is an 80% Lower?

What is an FFL?

An FFL, or Federal Firearms License, is a license provided by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (BATFE) to individuals and businesses. An FFL license authorizes an individual or business to manufacture, transfer, and sell firearms in the U.S. Such entities are referred as Federal Firearms Licensees. This guide details the available types of FFLs.

Do I need an FFL to build a gun?

Under federal law, no. An individual making a firearm for personal use does not need an FFL or other licensing to make a firearm. Certain restrictions apply. You cannot manufacture a firearm. Making a firearm for another person, or making one with the express intent of selling it, constitutes manufacturing. Manufacturing a firearm is illegal without an FFL. Some states have restricted this practice. Always check your local and state laws before ever making a firearm.

Questions About Ordering

Do you ship to California?

Yes. If you are a resident of California and are building a firearm using an 80% lower or receiver blank, you must first apply for a Unique Serial Number for the firearm via the California Department of Justice. 

Are 80% lowers legal in my state?

We cannot ship any of our products to New York, Nevada, New Jersey, Washington D.C., Washington state, Connecticut, Hawaii, or Rhode Island. Some states, like these, either severely restrict or ban the sale, ownership, and use of 80% lowers and certain other firearm parts we sell. Our shipping and return policy covers which states we cannot ship our products to.


Do I need an FFL to order an 80% lower?

Under federal law, no. Nothing we sell on this website is considered a firearm under federal law, including our complete build kits and 80% units. They ship directly to your front door without the need to conduct an FFL transfer. You do not need to submit to a NICS background check nor fill out a Form 4473 Questionnaire, as would be required with a typical firearm purchase. Some states do require background checks, or have restricted the sale and transfer of our products, which is detailed immediately below.

Do you ship to P.O. boxes?

No. We cannot ship to any P.O. boxes. Orders placed with a P.O. box as the recipient's address will be cancelled.

Do you ship internationally?

No. According to the ITAR (International Traffic in Arms Regulations) and EAR (Export Administration Regulations) Compliance Statement:

“By ordering any product(s) from website, you certify that you, or third-party entities at your direction, will not sell, transport, ship or transfer outside the borders of the United States, nor to any foreign person*, any product(s) which are export-restricted by U.S. export-control law and regulation, without proper U.S. Government export authorization, licensing, and documentation.

Export-restricted items include, but are not limited to, firearms, ammunition, electronic equipment, certain gear and firearm accessories, weapon-mounted or handheld optical equipment including rifle or handgun scopes, night vision and night vision accessories, holographic sight systems, “red-dot” optics, thermal vision, and tactical lights and lasers, knives, and body armor including vests, helmets and shields.

You must indicate on your order if you intend for an item(s) to be exported. An indication of the desire of exportation in no way compels to assist with export in any way, before or after purchase of an item(s). Export, or attempt to export, any controlled or prohibited items outside of the U.S. without complying with U.S. export control regulations can result in severe civil and criminal penalties and/or constitute a federal crime.

“Foreign Person” under ITAR § 120.16 means “any natural person who is not a lawful permanent resident as defined by 8 U.S.C. § 1101 (a)(20) or who is not a protected individual as defined by 8 U.S.C. § 1324b(a)(3)”, and can mean “any foreign corporation, business association, trust, society, or any other entity or group that is not incorporated or organized to do business in the U.S., as well as international organizations, foreign governments, and any agency or subdivisions of government (e.g. diplomatic missions).”

Why do stripped lowers have to be shipped to an FFL?

Unlike to 80% lowers, stripped lower receivers meet the requirements to be considered a firearm by the ATF. As such, they must be serialized and regulated under the Gun Control Act of 1968. A Federal Firearms Licensee is legally required to receive and transfer the lower receiver. Once the dealer receives your stripped lower, they will be able to do the necessary paperwork.

Questions About Building

How do I complete an 80% lower?

You'll need to invest in a tool called an 80% jig. These tools provide templates that show you where and how to fabricate your AR-type receiver into a functional firearm. Here's a more in-depth guide which covers this part of the project: What is an 80% Lower Jig?

Does offer any sort of warranty?

All of our products come with a Lifetime Warranty (read the full policy here). If your product is defective or inoperable by no fault of your own, please contact us immediately. For any additional info, read our complete refund and return policy.

Can my AR-15 chambered in 5.56 NATO shoot .223 ammo?

Yes, but the reverse is not true. If your AR-15's barrel is chambered for .223 Remington, we strongly recommend against chambering and firing 5.56 NATO rounds. Slight differences between both cartridges may cause a catastrophic failure in your firearm. This may result in serious injury or death.
