Has anyone noticed that a P-68 Magnum has more then enough space in front of the valve for 10 paintballs?
I have my next project! It will be spring fed from the bottom, load from the back one ball at a time and will have a 12-gram dropout on the side. Chances are that it will be limited to 8+1 or 9+1 after the spring and ramp are in place but I can deal with it. The double pump is (was and will be?) so smooth; this thing's pump stroke was smoother then any Sheridan (or any other pump for that matter) I have shot.
The little black mark below the end of the spring marks the end of the open space in the lower tube.
