Hello Instructables! Welcome to my instructable for my knex pump action shotgun. It was a large gun that uses an upside down crossbow mechanism. I will not post instructions for it simply because I do not want to. It was very fun to build and shoot. Advantages and disadvantages:
1. Pump action.
2. 12 round mag in the pump.
3. Pull strait back trigger mechanism.
4. Comfortable to hold.
5. Fired 35 feet. (Tested).
6. Six layers thick.
7. Looks amazing.
8. Full stock and butt plate.
9. Fires blue rods.
