The 8mm ammo. They are beads that I got from a discount store. They are Xmas decorations. I got the chain for 99c. Had about 300+ beads on it. All 8mm exactly and fly dead straight.

Cute, practical and it looks like it can easily be taken to 300 psi or more with quite a bit of power. Must be quite loud too, perhaps a longer barrel with a silencer over it?

Yeah thats definately in the books. at 150psi, it's pretty deafening. I'll get a meter long barrel pretty soon. It should do some pretty decent damage. Thanks for the comment Jack :D .

Hey
Once again, very nice gun, as usual nice clean construction and a functional, ergonomic looking design.

After my sniper gun, i might make a piston...
*throws study notes away and runs to the drawing board*

EDIT: I meant "After my sniper gun, i might make a pistol... "

so i am guessing its a piston valve? And if it is, what is it made of, the sealing face, bumper and stuff. If its not, then what is the sealiang valve?
That definatley looks like something to have fun with when i am bored :D

It's coax in the sence that the barrel runs through the chamber but its a T valve aswell because it seals inside the T. The elbow that the blowgun is off, thats where the piston is. I don't have a bumper but I've got a spring that keeps the piston against the barrel. I had to do it that way because I don't fill from behind the piston. My sealing face is just this soft rubber that I got from the plumbing shop. Hope this helps.

this is a real beauty :) If you got a meter long barrel it wouldn't really look like a pistol any more :( maybe get like an extra 10" extention and that could be the silencer, threadable of course :wink:

BOOYAH! I'm a genious. I give myself an erection my ideas are that good! hahahaha. I've got a compression tee that i bought for the 1st bb gun idea. It's comp on the sides, but the middle is a female thread. As everyone knows, a comp elbow/tee is just a male fitting with a compression coupler that it screws onto.

Well...I've had trouble making a decent looking flush stuck out of metal with the elbow I got on there now. As everyone can see, it's one of those ones with the lip on it so it can bolted to a wall. Well....with this new idea, I screw my blowgun into the female at the bottom of the T, take off the comp coupler thingo off the right hand side and screw that straight into the guns existing tee. With the last side, leave that as a compression fitting. I have a stack of 1/2 copper pipe so I'll make a flush, pollished stock out of it. It's gonna look soo good and work so well!

Any idea's or critisism is more then welcome.
