80% lowers for untraceable firearms.

It is an AR-15 lower receiver that is “80%” finished, you have to do some milling, possible with a drill. This fits the definition of manufacturing your own firearm, and thus, you do not have to serialize or register it as long as it remains in your possession.

If your state has a ban on 80% lowers, you can 3D print a lower receiver. I recommend the Hoffman Tactical Super Lower, very sturdy design. Use PLA+ from polymaker or carbon fiber nylon if possible. If using CF Nylon, spray paint it to prevent carbon fibers from shedding into your skin.

If for some reason you cannot obtain any AR-15 parts, look into the FGC-9, it can be produced with 3D printing and common hardware, and is designed to be made in places where guns are completely banned.
