This is my first post, so be kind. I'm 19 years old and have been aspiring to be a gunsmith since I was 8 years old. I was blessed with acess to a machine shop over the last 2 years, and I would say that I am a skilled machinist. Well here it is, it's a closed bolt hammer fired SMG, semi only of course. The bolt is the rear of a CZ handgun slide I hacked off. It took eight months from idea to finish, and since no-one has ever made this particular gun before there were problems every step of the way. I live in nevada so it's toatally legal. If any one is interested in this ill post schematics and more pics.
