Volume 6 of Professor Parabellum's Practical Scrap Metal Small Arms.
This volume provides plans and instructions on creating a 100% DIY MAC-10 submachine gun using only basic materials and tools.
"Detailed herein are plans for a 1:1 copy of the MAC-10 submachine gun, the only differences being the internals having been simplified for ease of home manufacture. For readers familiar with The Box Tube MAC-11 design described in Vol.2 & 5, the construction techniques and tools used in this project are very similar. The design described here is slightly less expedient, though what results is a highly accurate reproduction of the original weapon which will match many factory made examples in quality if care is taken. As before, no lathe or milling machine is needed and only very basic tools are required for construction."
