This is a technical manual that was created for a purpose bigger than the object itself. It is a step by step guide for crafting a submachine gun (prop) using only hardware store material and tools. Because of much trial and error as well as research, I am confident that it is the BEST submachine gun prop that can be built without; lathes, milling machines and other specialized equipment, or commercially produced firearm components. To be the "best" means not only function but many other considerations as well; prevalence of material, mechanical skill needed to craft, durability, simplicity, and others. This is not a hastily thought out design, and because of that I would like to share it with you to save you from making the same errors that I made. Most people would ask "why", but I'm confident that well informed Americans with a certain level of foresight will know in their bones exactly why this book should be acquired now and kept on the shelf. I don't have the ability to express this idea properly but the basic foundation of it is; the minions of tyranny and evil will be less willing to walk thru a door if they are uncertain of what's on the other side. This manual is meant to add to that fear of the unknown, whoever they are, and whenever they come.
