This manual describes a simple, cost-effective method of converting your Cobray M-11/9mm into a full-time, full-auto sub-machine gun. Although this conversion does not change the M-11 into a full fledged M-10 S.M.G., it will provide details for the proper modification to the M-11, creating an M-11 S.M.G. The process is easy and takes but one afternoon of tinkering to get itjust right. 28 pages, 5.5 x 8.5
