Blackheart Crossbow String 31 In. Excalibur Matrix

The Blackheart Crossbow String 31 In. Excalibur Matrix is purpose-built for hunters who demand reliability and consistency from their equipment season after season. Designed specifically for Excalibur Matrix crossbows, this replacement string combines modern composite materials with traditional bowstring craftsmanship to deliver the silent, accurate shot placement that separates successful hunts from missed opportunities. Whether you're preparing for the upcoming season or maintaining equipment from previous campaigns, a quality bowstring is non-negotiable for peak crossbow performance.

This bowstring features Blackheart's proprietary GlideLock center serving, a refinement that reduces friction between the string and crossbow components while minimizing serving separation—a common failure point in field-worn equipment. The 31-inch length is precisely engineered for Excalibur Matrix specifications, ensuring proper draw length, cam timing, and arrow flight characteristics. The advanced material blend resists the environmental stresses that degrade lesser bowstrings: temperature fluctuations, moisture exposure, and the repeated shock cycles inherent to crossbow use. The reinforced serving also eliminates the ridges that develop between serving strands, preserving string integrity and consistency across hundreds of shots.

Excalibur Matrix crossbow owners recognize that string replacement is essential maintenance—typically recommended every 2–3 years or after 500+ shots, depending on frequency of use and storage conditions. Installation is straightforward for users familiar with crossbow maintenance; however, improper installation can compromise accuracy and safety, so professional installation is recommended for first-time users. This bowstring's compact 0.15 lb weight and compact dimensions make it ideal for field kits or backup string storage, ensuring you're never stranded without a replacement during extended hunting trips.
