Designed to replace existing harmonic dampers and stabilizers on Mathews compound bows, this Riser dampener from LimbSaver provide improved performance in vibration control with reduced weight compared to other riser dampeners. Durably built to be used outdoors in harsh environments, LimbSaver's Riser dampeners help to reduce stress on your hands and arms while shooting. Simply snap the Riser dampeners into damper holes and you’ll feel the difference on your first shot. They're made from LimbSaver's proprietary NAVCOM technology (Noise and Vibration Control Material), which effectively absorbs a wide range of frequencies to dissipate energy and vibration for improved comfort as well as deadening and silencing your bow. This package includes two Riser dampeners. Using state-of-the-art technologies, LimbSaver produces highly effective noise- and vibration-dampening products for archery and firearm products, including bow stabilizers, recoil pads, rifle slings, and more. Proudly engineered and hand-made in the USA, LimbSaver products are widely used by outdoor enthusiasts, military, law enforcement, and more.
