This is a little brick shooting pistol thats single action. It can also shoot little technic rods. I have instructions for the mechanism.
About this creation
Looking down the sights. Sometimes when you shoot a brick it will jam andspudder out the barrel. Thats why I usually just shoot the rod out. When you shoot it without a brick the rod will shoot out.
It's so simple, it would have to work! Honestly great work on this. You should try making a larger gun with a top-mounted clip for more technic rods. When the "ram rod" is relaxed, it stops the next rod fro comming down, and when it is pulled back, the next round falls into place.
