Tyler's Air Soft Gun.

Unread postAuthor: tylerthetatertosser » Mon Oct 29, 2007 12:35 am

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 :roll: :D

I think the barrel is 5/16 brake line, and i can get it up to 200 psi with my regular bike pump

Very nice gun. Can you shoot through both sides of a water filled pop can?

I think you need to build a high pressure pump and take it to 300psi

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!

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

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