Response to 392 carbine progress update
If you ar concerned about the stroke, purchase a Benji HB pistol inlet valve. It is shorter in length AND has much less volume. You would see gains immediatley on 10 pumps. However, you will then need to add some length to the factory piston (slightly less than 1/2"). To do this, (1) you can cut the piston rod then thread both ends (1/4x20 threads) or, (2) heat up the end where the lever link attaches and pull out the piston rod and thread the hole to 1/4x20 thread and the piston rod. You then would need to use a sleeve nut to capture both ends.
As far as the slot. The slot should have needed to be extended the same amount that has been removed from the tube, (edit) that's if you were using factory components. I did not scroll far enough to see the piston unitl later - oops. Put a rod in that piston (make it longer), problem/stroke will be solved.
Survival Benji? Now time to bed liner the stock.
