Cursed Homemade Gun: Straight Pull 9mm

This is another one of my homemade guns. I built this gun about 15 years ago so don’t judge too much. This is definitely a cursed gun with a steam punk look. I built this gun before I had a metal lathe and mill, so it is rather rough. This is a straight pull manual action rifle is chambered in 9mm parabellum and uses 20 round Sten magazines. There is a locking bolt on both sides of the rifle that lock into the tube receiver. The stock was borrowed from an old Springfield shotgun, and the trigger mechanism is a modified H&K or Cetme trigger. Originally I had a 4x scope on it, but put a red dot on it for demonstration. The barrel is 16" long was designed to go in a Russian PPSh. It has an extractor and ejector. Thanks, be safe and God bless.
