The Rattler adjustable bow string silencer was developed as a bow string suppression device to fit any compound bow with a front or rear mounting stabilizer hole. Constructed out of aluminum and titanium, this is the most advanced and clean looking unit on the market today, it almost looks like it is part of the bow and just not another add on. The unit is very easily installed by either attaching to the front or rear mounting hole, sliding the shaft out until the rubber bumper touches the string, and lock the set screws in place with the allen wrench that is provided.
It will mount in the "front stabilizer port" he speaks of.
