80% Lowers

What is an 80 Lower Receiver?

An 80% Lower Receiver, sometimes called “80 lowers” or “a paperweight”, are AR-15, .308, or AR-9 lower receivers that are 80% finished in the machining process. There’s still a small amount of finishing to be done to make these products a legal firearm. This is important because the ATF does NOT recognize an 80% complete lower as a firearm, and therefore is not subject to the same regulations as any other complete firearm. This means, no RED TAPE including:

NO Registering an 80% Lower   NO Transfer fees like a typical firearm   
NO FFL Required, Ships right to your door
