The all-new MP2 ushers in a new era of plungers. With no mechanical parts and superior material selection the rain and temperature have less of an effect than traditional plungers. Micro adjust your center shot with 20 clicks per rotation. New tool less adjustment makes it even easier to move. Includes a new metal wrench for better tightening to the bow. The MP2 dynamic nonlinear response creates a forgiving and consistent plunger.
