80% Lower Receivers

What is an 80% receiver?
An 80% Receiver is a partially completed piece of material that requires special tooling and skills to be completed and considered a firearm. Unlike a firearm receiver it is not required to be transferred through a Federal Firearms Licensed holder (FFL).

A lot of questions have been raised about how our 80% AR-15 Lower Receivers can be considered non-firearms. We've received a copy of the determination letter from the ATF stating that the ATF does not view this as a firearm because to complete the receiver it requires specialized skills and tooling.

Do I need an FFL to make a firearm?
In short, no. As long as you can legally own the firearm in the state, county and city you reside in you are allowed to manufacture a firearm for your own personal use. No serial number is required however it is suggested to engrave a distinctive marking on your receiver in case it is lost or stolen.

Recommended Tools 
Completing an 80% Lower Receiver can be accomplished using a variety of tooling and methods, the most common methods require using a manual mill or a drill press. Both manual mills and drill presses can be purchased off web sites like craigslist or ebay as well as from local tooling suppliers. Once you have the machine of your choice, end mills and drills will be required to complete the remaining operations.
