Abstract
Abstract A bow stabilizer is mounted to an archery bow for the purpose of balancing the archery bow and reducing recoil, shock and vibration forces and noise that results when an arrow is discharged from the archery bow. The bow stabilizer has a hollow body which defines a chamber. An end plug is sealably secured to an end of the hollow body and another end plug is sealably secured to an opposite end of the hollow body. The bow stabilizer has at least one counterweight which is adjustable along a longitudinal axis of the hollow body to balance the archery bow. The chamber of the hollow body is partially filled with granular solids.
