I built a pneumatic riot gun I sleeved the steel pipes with rubber inner bike tube.Very effective against scratches and such on a metal gun.Makes it look cool too.Satin black.
But enough talk...Let's see the pics

First some damage to a steel can.The entry hole runs from one side to the other.Viewed from the front it nearly cuts the can in half.The exit hole is smaller but looks much more jagged.Bent the entire can out of shape.

Riotgun long barrel version 26mm bore.Max pressure 25 bar.ammo= 1"marbles.Here you see a closeup of the ballvalve, trigger and grip.

The pressure gauge and the schrader valve are on the ballvalve on the piston side.Foam grips.The gun is very powerfull.I shot a 1"marble trough 2 layers of plywood and it stopped by putting a dent in the wall behind the wood.Big noisemaker this one.

I like it very much! That curved end makes it look like a pump action shotgun or something like that ,anyway. Pretty and dangerous.. Lethal combination.

slim design, takes up very little room and still packs one hell of a punch, good job, are the pipes copper or stainless steel ?

Reservoiris stainless steel, the one that holds the piston and the barrel aren't because the steel pipe is'nt smooth on the inside so I had to use copper.That curved piece came from an ab-roller as well as the foam grips.
I planned to rent a pipe bender we have down here as a simple plumbers-tool to bend copper pipes.( hand held thing)The ab-roller was just collecting dust so I thought it might be cheaper just to use that.It turned out better that I expected because the diameter is also 28 mm.No pipebenders are available in that size.
At first I wanted to get he sawed-off look but I won't get a lot of power from a short barrel.might lookawesome though...

I modded some of the couplings to fit into one another in order to get it this slim.If you look at the middle picture you might see that the bottom tee is fitted into the top one.

This is the version of the riot gun before it became a sawn-off. You probably want this page:
