Looking to practice your drilling or build skills? Well, look no further than these genuine Polish 60% AK receivers! Why are they 60%? The basic shape has been done for you, but they need the center support drilled and riveted, plus metal hardening and guide rails welded in. With some work they can be made into beautiful AK receivers. No serial numbers or holes drilled, just the basic sheet metal receiver shape. Some have surface rust that will clean up once refinished. Any questions feel free to ask. No returns on used items
