I purtied it up a little

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.
