Abstract
B/D archery bow accessories which have an elastomeric vibration dampening component mounted on an elongated, rigid support. The elastomeric component has a set of integral vibration dampening elements such as ribs. The vibration dampening elements have irregular profile configurations which make these elements capable of dampening with high efficiency the sets of vibrational frequencies generated: (a) when an arrow is shot, and (b) during and after the ensuing lock-up. Vibration dampening efficiency may be promoted by making the elastomeric component from a material of the most optimal hardness that is practical and by employing end pieces at opposite ends of the elastomeric component.
