80% Lower FAQs

Frequently Asked Questions about the 80% Lower Receiver


How do I order an 80% lower receiver?

The ordering process is simple. Choose your 80% lower from the available options and follow the steps to our secure, online checkout. Our customer service team is available to answer further questions about specific products and order information. They can be reached on our Contact page.

What is an “80% lower receiver”?

An 80% lower receiver goes by a myriad of names: “Unfinished lower”, “80 lower”, “unfinished receiver”, and many more. All those terms typically refer to the same product. The 80% lower gets its named because it is only 80% manufactured. Part of the lower remains un-fabricated. Until an 80% lower receiver has had its fire control cavity milled out (using an 80% lower jig), it is, by law and found in the Gun Control Act of 1968, NOT a firearm. Once a single hole is drilled into the 80% lower receiver, it then becomes, by law and definition, a firearm.

Are “80%” or “unfinished” receivers illegal?

No. The Bureau of Alcohol, Tobacco, and Firearms (ATF) has clarified that receiver blanks that do not meet the definition of a “firearm” are not subject to regulation under the Gun Control Act of 1968. For further clarification directly from the ATF, click here.

Does the ATF know about 80% lower receivers?

Yes, as they’ve clarified above. However, an 80% lower receiver is NOT a firearm. Therefore, purchasing and owning one does not require the paperwork or regulations that govern the purchase and ownership of a firearm. Click the link provided above to read the ATF’s take on 80% lowers, or, as they call them officially, “receiver blanks”.

Can AR-15s made from 80% lower receivers be traced?

An AR-15 built using an 80% lower will have no serialization or paperwork attached to it by default. Therefore, it is typically impossible to determine the firearm’s origin or history. Some states (like California) require 80% lowers to be serialized before they’re completed. Residents in California should contact the CA Department of Justice and submit a Unique Serial Number Application before machining their 80% lower.

What is an FFL?

An FFL is a Federal Firearms License. It is a required document for the transfer or sale of a FIREARM in the United States. The Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) grants FFL licenses.

Is an FFL required when I purchase my 80% lower?

No. An 80% lower receiver (which is the ONLY type of lower receiver we sell) is NOT a firearm so an FFL is NOT required to buy or sell.

Where can I find more information regarding my state laws and 80% lower receivers?

The NRA website is a great resource for citizens to familiarize themselves with their states laws regarding firearms.

Do you sell to New Jersey?

New Jersey’s attorney general recently demanded that companies stop marketing and selling untraceable weapons or “ghost guns”. Therefore, we are not allowing sales or shipping of any of our items to the state of New Jersey. See N.J.S.A. 2C:39-9g

Can I export these products out of the country?

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

“By ordering any product(s) from 80-lower.com 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 80-lower.com 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).”
