spud guns I've made

These are spud guns I've made. Nothing elaborate, but all shoot great.
The first on is a breech loading rifle with a 1 in. barrel about 40 in. long with a 2 in. air chamber. The ball valve open back so I can hold on target.
The second one is basic spud gun with a 1 1/2 in. barrel that is 4 ft. long. with a 2 in. air chamber.
The 3rd on is a piston valve made from a soup can with a toilet flapper as a seal and a rubber bumper on the end of the can. The barrel is 1 1/2 in. with a 3 in. air chamber. The exhaust valve and fill valve are built in the screw on cap.
The last one is the first gun I ever built. It has a 2 in. barrel and a 2 in. air chamber. The valve is a 3/4 in gas valve. The gas valve inner threads were notched out on 2 sides and the stem threads were filed down on 2 sides. A spring is between the valve and the handle. When you pull back the lever handle the stem lines up with the notches in the valve and moves stem out for a quick release of air.
Push the handle in and forward for the next shot.
