An 80% lower is not by definition a 'firearm'.

An 80% lower receiver is a partially completed piece of metal that requires special tooling and skills to be completed, a trigger assembly, and a complete upper to be considered a firearm. Unlike a stripped receiver it is not required to be transferred through a Federal Firearms Licensed holder (FFL).

Just as the term '80% lower' is defined. It is not a 100% usable item.
The finishing of the product in order for it to be usable comes from the customer 'finishing' the lower.

A lot of questions have been raised about how 80% AR-15 lower receivers can be considered non-firearms. We get the receivers milled to the furthest legal capabilities without needing an FFL to transfer them. We’ve also received a determination letter from the ATF stating that the ATF does not view this as a firearm because in order to complete the receiver it requires specialized skills and tooling.

This being said StealthArms, LLC. is not a firearms manufacturer.

Do I need an FFL to make a firearm?

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 serial number, model and manufacturer on your receiver in case it is lost or stolen.All National Firearms Act (NFA) regulations apply to your firearm. You may create a short-barreled rifle out of your firearm via a BATFE (Bureau of Alcohol Tobacco Firearms and Explosive) Form 1 after BATFE approval.
