Blackheart Crossbow String 36 In. Barnett Brotherhood

The Blackheart Crossbow String 36 In. Barnett Brotherhood is a precision replacement string engineered for hunters and competitive shooters who demand reliability in the field. This 36-inch string is purpose-built as an OEM-compatible replacement for Barnett crossbow models within the Brotherhood platform family, ensuring exact fitment and consistent performance shot after shot. Whether you're replacing a worn string or upgrading to fresh equipment before hunting season, this component is essential for maintaining your crossbow's kinetic energy transfer and accuracy.

Constructed with high-tenacity synthetic fibers and proprietary weaving geometry, the Blackheart string resists stretch and fatigue over hundreds of shots. The 36-inch length specification ensures proper draw geometry and force curve alignment with the Barnett Brotherhood limb assembly, maintaining optimal kinetic energy delivery and minimizing string creep—a critical factor that degrades accuracy over time. This string's compact weight of just 0.15 lbs reflects modern material science, reducing stored energy loss while improving overall bow handling and speed consistency across varying draw weights and ambient temperatures.

Replacement is straightforward for owners of Barnett Brotherhood crossbows, though proper installation using a string jig or bow press is recommended to maintain cam timing and prevent limb torque. Users will notice improved shot grouping and reduced hand shock once the new string is properly tuned and break-in cycles are complete. This string replacement is an affordable maintenance interval that extends crossbow lifespan and ensures peak performance for 3D competition, hunting applications, and backyard target practice alike.
