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.
