ghost gun

A partially finished firearm that you complete yourself.

A firearm assembled from parts made on a 3D printer.

Since a completed firearm with a registered serial number was never sold, then it is argued that it is untraceable so the label "ghost gun" is used to describe it.

Lower receivers on modern sporting rifles that are only partially completed and it is left to the individual, usually with machining tools, to turn it into a functioning weapon.

With the advent of 3D printing it is becoming possible to make parts that can be assembled into a functioning firearm.

The assembled parts are referred to as a "ghost gun" because the lack of a registered serial number or paper trail makes it hard to trace.
