Blackheart Crossbow String 36 In. Excalibur

The Blackheart Crossbow String 36 In. Excalibur is a precision replacement string engineered for hunters who demand reliability in the field. After countless seasons spent pursuing game across varied terrain, serious crossbow enthusiasts understand that a quality bowstring is non-negotiable—it directly affects accuracy, consistency, and the longevity of your equipment. This 36-inch string is purpose-built for Excalibur crossbow platforms, delivering the performance and durability that modern hunters expect when accuracy matters most.

Blackheart strings are constructed using a carefully balanced combination of modern synthetic materials and time-proven manufacturing techniques. The standout feature is the GlideLock center serving, which significantly reduces friction during the draw cycle while minimizing serving separation—a common failure point in lesser strings. This design almost entirely eliminates the ridges that develop between serving strands on inferior bowstrings, promoting consistent arrow flight and extending the operational lifespan of your crossbow. The result is a string that maintains its performance characteristics through dozens of hunting seasons without premature wear or creep.

This replacement string is ideal for Excalibur crossbow owners seeking a factory-equivalent upgrade or those replacing a worn string to restore their weapon to peak performance. Whether you're preparing for the upcoming season or maintaining equipment between hunts, the Blackheart Crossbow String 36 In. Excalibur ensures that equipment failure never costs you an opportunity. The compact packaging (weighing just 0.15 lbs) makes it easy to keep as a backup in your gear bag, and installation requires no special tools beyond basic crossbow maintenance knowledge.
