What is disclosed is a slideable weight for use on an archery bow. The slideable weight is configured to travel from a position near a limb of an archery bow or a pulley of a compound archery bow toward a midline of the bowstring. This creates a catapult like effect that increases the speed of an arrow released from the bow. The device can conceivably be used on any archery bow, including compound, recurve, or other bow.
