Excalibur S5 String Suppressor

The Excalibur S5 String Suppressor is a purpose-built noise dampening system designed for crossbow hunters who demand stealth in the field. After decades of hunting, the string vibration from a crossbow shot is one of the most telling acoustic signatures—alerting game well beyond the bolt's impact. This accessory addresses that critical weakness by absorbing string oscillation at the source, reducing report and vibration noise that can spook nearby animals during multi-shot scenarios or when hunting in close-quarter terrain where sound travels unpredictably.

The S5 suppressor employs elastomer dampening material positioned directly on the string assembly to absorb and dissipate vibration energy before it radiates outward. This design minimizes the sharp crack associated with string release while maintaining crossbow performance and shot consistency. Weighing only 0.4 lbs, the suppressor adds negligible mass and does not affect draw weight, velocity, or accuracy—critical factors for hunters who have dialed in their ballistics over countless seasons. The compact profile ensures it does not interfere with reload cycles or interfere with sight lines, making it a transparent upgrade to your existing setup.

Excalibur S5 String Suppressors are ideal for serious crossbow hunters pursuing deer, elk, and other large game where a silent shot is the difference between a clean harvest and a lost opportunity. The suppressor pairs seamlessly with Excalibur crossbows and compatible platforms, requiring no gunsmithing or special tools for installation. Whether you hunt thick timber where sound echoes or open country where animals react to noise within seconds, this accessory is a proven field solution that addresses one of the few remaining variables in modern crossbow stealth.
