Sold with the cut codes to complete selected 80% lowers and frames such as the AR-15, AR-308, and the M1911, the Ghost Gunner 3 takes it name from its third-generation, custom motion-control board, which allows it to operate as a standard CNC machine. GG3 accepts g-code from most CAM post-processors. To use the GG3, you only need to provide the desired frame/lower and corresponding jig set (sold separately) and any computer or laptop with a windows or mac OS.


For best results, use 80% lowers/frames from Defense Distributed although we here at GGD specialize in providing jigs and code to work with an ever-expanding selection of frames and lowers.

Ghost Gunner 3 CNC Machine (Ships in Q4)

  • Product Details

    Ghost Gunner 3 is a general purpose CNC mill that gives you the ability to finish 80% receivers and frames with ease, in the comfort of your own home.

    Ghost Gunner 3 is a complete redesign based on the successes of the GG2. It uses a milled, precision unibody frame for sharply improved squareness and rigidity. Optical limit switches and pre-loaded, self-aligning ballscrews allow it to deliver advanced positional accuracy.

    GG3 incorporates a custom motion-control board with a closed loop, digital VFD controller. The machine accepts g-code from most CAM post-processors, and supports tool diameters up to 8 mm (~5/16”).

    Included with the GG3: A DD USB with all our latest software. ER-11 collet nut, 5/16″ allen wrench, 3mm ball-end allen wrench, 12mm wrench, 17mm wrench, 6′ USB A-B cable, 6′ three-prong power cable. Laptop not included.
