80% lower Receivers, often called 80% lowers or 80 lowers, are lower receivers of the AR-15, AR-9 and .308 AR platforms which are “80%” complete. The area which houses the trigger, is not milled out, and therefore considered an 80% lower, because there is still machining that needs to be done.

Does An 80% Lower Need a Serial Number?
Except for a few states, 80% lower laws do not require a serial number as they are not classified as firearms until after they are built. The serial number is generally necessary for transfers and sales of firearms, but 80% lowers are not legally defined as firearms, and therefore do not require a serial number. Here are the states where serial numbers are required on 80% lowers, or where are they are not legal to purchase:
80% lowers are not legally firearms until they are machined to be 100% legally definable firearms. This means that if you want to sell one after you have already machined it, you are trying to sell a firearm. It is illegal to sell a firearm from a receiver blank if the firearm was built with intent to sell. This requires an FFL in order to do so. However, if you no longer wish to own your 80% build, a private transaction can occur which is completely legal.
