This is my Air soft co-axial cannon. I have had this for a while but never posted.
The over all length is about 16.5 inches, the barrel length is 12 inches, and the chamber is 1/2" type L 12 inches long. The piston is cast from epoxy with an inner tube crazy glued on for sealing face.

looks like good shock pump material, what pressures are you using?
Kudos for the cast epoxy piston, shame about the excess pilot volume

Why the quick disconnect? All it's doing is making your gun less efficient.
In place of it you should put a bushing that will bring it down to 1/4" FPT. Connect it to the blowgun using a close nipple.
Otherwise, nice gun. It should be safe enough to take way beyond 100 psi. Post pics of the damage!

how is the barrel held in place? how far was your shot from?
The barrel is held in palace with epoxy, and the shot was from about a foot away from the can.
Why the quick disconnect?
I use the quick connect because i have 3 copper pneumatics and one blow gun, i will get more blow guns for $ 3.99 ea when i go to a city 2 hours away.

Nice gun, and like jsr i know that you can reduce the pilot volume alot and that would lead to huge improvements in performance
The Doors are awesome, Led Zeppelin is amazing, and Motley Crue kicks @$$.

Nice little co-axial you got there.
Have you shot it at farther distances, and if so how accurate is it?

The ture test of any gun has to be more than 1 foot away................I think at least 20 feet away.......Thats just my thought.....

Nice gun by the way!
