ONLY AVAILABLE TO U.S. CITIZENS
Firearms designer Mark Serbu unleashes the concept for his GB-22, a homemade four-piece .22 rimfire single-shot handgun that can be crafted by virtually anyone.
Sold in paper format, no electronic copies.
With only a barrel, frame, slide and recoil spring, the GB-22 can be made at home with steel plate and bar stock by use of a hacksaw, file and drill. Attaching the barrel to the frame can be done via welding, roll pins, or screws. The roll pin method is detailed in the plans, though the user can easily adapt them to welding. The concept is to be able to make a simple, working gun for whatever reason you want– though he stresses that you could sell these at gun buybacks for a profit.
Of course his example is a little tricked out with an optic and some custom grips, and he makes the prototype on CAD/CAM-controlled CNC machines because it's easy to do and he has access to them. He stresses you can craft virtually the same with hand tools; it just takes more sweat equity.
If you don’t want to buy a spring he even shows you how to make your own out of music wire!
