Ghost Gunner 2

Ghost Gunner 2 is the second iteration of an open source project specially designed to manufacture a growing library of mil-spec 80 percent lowers 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 rifles and pistols in the comfort and privacy of home.

True CNC
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 unibody machined spindle and has a machinable area of 8.25″ x 2.95″ x 2.35″, optimized for machining AR-15 & AR-308 lowers and pistol receivers.

Beyond files of the .DD format, Ghost Gunner is meant to accept TinyG code from any CAM program. This allows you to mill whatever design you might want so as long as the material no harder than aluminum and fits within the maximum machineable area. Ghost Gunner 2 is not able to mill steel or other harder materials.
