Abstract: A stabilizer for an archery bow includes an exterior tube, with end caps at each end, with a central shaft supported within the tube between the end caps, and projecting beyond an end cap for threaded attachment to the bow. Various piston weights and resilient dampening elements are provided and slidably mountable on the shaft within the tube; the number and sequence of weights and/or dampening elements may be selected to customize the stabilizer to a particular bow or the preference of the archer. The assembly of weights and/or dampening elements are held on the shaft between collars, which may be moved along the shaft to adjust the center of gravity of the stabilizer. The collars may be adjusted to apply compression against the assembly to adjust the vibration dampening characteristics.
