This is a complete bolt assembly for the Madsen M1950 9mm SMG. This is the clam style gun. This bolt has the firing pin (yes it is removable), extractor and retainer pin, cocking handle and its retainer. Ready to drop into your gun or a great spare part to have around. This gun uses a double column single feed type magazine. The later M56 or Type II used a double column double feed magazine and a different bolt.
