I was cleaning out my shed and found the stock to my pneumatic crossbow prototype. I decided to refine it a little and use it as a stock on my copper piston gun. I also found about two feet of aluminum the right size for .177 bbs. I connected it too the small piece of copper on my gun using an aluminum sleeve and some epoxy, then supported it with some golf club shaft. I used mecano to hold the copper to wooden stock, the screws allow me to take copper gun off if I need to service it. I put a rare earth magnet in the stock just infront of the piston to hold the bbs in place. I also used mecano to make a scope mount for an old scope i had.

A friend gave me 10' of 3/4" copper so I decided to make a small co-axial pistol. I had about 2' of some small diameter copper tubing lying around so i just bought a couple fittings and threw this gun together in an afternoon.

This is my second piston gun but is considerably more powerful than my marker gun. Easily goes through cans and most things I put in its way. Its filled and piloted through a blow gun I just put it in my compressor press down the blow gun, let go, then release the quick connect. Its fast and easy.

Nice for a second piston valved gun.

But you put the blowgun on backwards...
Because of how they work internally, the seal will fail if you have too much pressure on what is supposed to be the output of the nozzle.

Now all you have to do is build it up a little to look more like a large pistol.

Yes!

Whether you built it up like a pistol or a rifle I would have been happy.

Very nice touch with the magnet.

You did indeed "purty" it up a little. :wink:

I think it might have gotten a little bit bent, but I redid the barrel with a different super light golfclub shaft and covered the whole thing in fiberglass.
