For The AR-15

No prior CNC experience required

As shipped, Ghost Gunner manufactures mil-spec AR-15 and AR-10 lower receivers to completion. With simple tools and point and click software, the machine automatically finds and aligns to your 80% lower to get to work. No prior CNC knowledge or experience is required to manufacture from design files. Legally manufacture unserialized AR rifles in the comfort and privacy of your home.


Ghost Gunner is built from rigid plasma-cut A36 steel and 304 stainless steel. The machine part count is greatly reduced compared to traditional CNC machines, which both increases rigidity and decreases cost.

GG2 employs a horizontal milling format, a 10,000 rpm ER-11 collet spindle and has a machinable area of 8.25″ x 2.95″ x 2.35″, optimized for machining AR-15 and AR-10 receivers.

No registration or serialization required

Due to Federal regulatory overreach, Ghost Gunner is now the only affordable CNC solution for privately finishing your 80% lower receivers. The first of its kind.

Programmable, Personal

Beyond files of our own .DD format, Ghost Gunner is meant to accept TinyG code from any CAM program. The platform is open and the plans and files will be disclosed to the public domain.
