Mostly as described, but came with two of the same springs needed to vary stiffness range. It was supposed to come with 3 different springs. Still a good value. Could improve the smoothness of the internal diameter bore, and the machining on the plastic plungers. They feel like a stair step force rather than a smooth increase in plunger force. This will likely increase the side to side shot variability a little. Obvious Bieter Plunger knock-off. Ya get what ya pay for.
