The first pic is the original, guys. This is my Knex Shotgun. It's a true semi-automatic knex gun. Hold six shells (bullets) and is jam free. Also this gun is very reliable and of my own design.
With small .64 rubber bands i got it to shoot 50-65 feet. I rebuilt the stock and the handle is more comfy, also the trigger is better! Rudimentary sights, open to ideas, put any improvements you can think of in comments pls.(or pm me)
