Product Number: 1990Excalibur’s Dissipator Bar uses an ultra modern energy absorbing compound to tame recoil energy and noise on any Excalibur crossbow except Matrix Series crossbows. This lightweight accessory reduces noise by as much as eight decibels but does not reduce arrow velocity in any way! A Dissipator Bar kit comes with bars, pads, and mounting accessories.Designed to fit older Exo series crossbow models such as: Exocet, Equinox, Phoenix, Exomax and Vixen. The string will need to be removed to install this kit so we advise you also purchase a 2096 stringing aid found here on our site
