No piston weight, just delrin washer and top hat. Spring is a HW one, with id guess about 40-50mm of pre-load from memory. Don't get me wrong, it shoots quite nice but according to all theory it should be wonderful at this spec and its not that easy to shoot accurately with. It brought it home to me after having shot the Diana 34s for a couple of weeks just how much sight picture was lost when pulling the trigger.Originally Posted by Shed tuner
