Blackheart Crossbow String 37.938 In. Barnett

The Blackheart Crossbow String 37.938 In. Barnett is purpose-built for hunters and competitive archers who demand reliability from their crossbow systems. After decades in the field, the difference between a quality bowstring and a marginal one often determines whether a season ends in success or frustration. This 37.938-inch string is engineered specifically for Barnett crossbow platforms, where precision fit and consistent performance are non-negotiable. Whether you're hunting whitetail at forty yards or testing your skill at the range, a properly matched string is foundational to accuracy, energy transfer, and repeatable shot placement.

Blackheart strings combine modern high-performance materials with time-honored bowstring construction methods to deliver durability in harsh field conditions. The signature GlideLock center serving reduces friction between the string and the flight rail, which translates to less energy loss on the shot and improved arrow velocity consistency. This serving design also minimizes separation and eliminates the ridges that typically form between standard serving wraps—a detail that prevents the string from sagging unevenly and causing cocking issues. The 0.15 lb weight keeps the overall system balanced, and the compact 5 x 1.5 x 14.88 inch package ensures easy transport and storage in your hunting pack or equipment bag.

This string is ideal for Barnett crossbow owners who recognize that replacement and maintenance intervals are part of responsible equipment stewardship. Over time, even quality strings experience stress and micro-damage from the explosive energy release of each shot; swapping in a fresh Blackheart string restores the factory performance your crossbow was engineered to deliver. Hunters operating in cold climates, wet environments, or high-volume practice sessions will appreciate the serving's resistance to friction-related wear. Installation requires only basic crossbow maintenance knowledge—simply measure your current string to confirm the 37.938-inch length matches your Barnett model, then follow standard string-replacement procedures to ensure proper cocking and rail alignment.
