The purpose of these instructions is for the average person, with average skills and equipment, to construct a simple 22-caliber revolver. I have read a lot of books on how to make homemade guns and what I have found is that there are two extremes. At one end of the spectrum, you have the crudely made single shots that are impractical and more dangerous to the person firing the gun than to their target. At the other end, you have complex guns, like semi and fully automatics that require you to purchase specialized parts and materials, such as barrels and springs from a supplier. You must also have or have access to expensive machine tools. It takes an experienced machinist or gunsmith to make these firearms. What I have come up with is a good happy medium.
