the final full schematic is on the server linked below under valve.04
In .22 this will do 90ft/lb and is good for 25-30 full power consistent shots. In .45 with the 119gr slug it will manage 7-10 shots and 400ft/lb.
It will fit into the standard Talon and condor bodies. Fill pressure off a standard bottle is 230bar.
We need to refine the valve a little for production before it WILL be offered for sale via this forum.
