Excalibur Matrix Crossbow String

This string is specifically engineered for the Matrix and Bulldog series. Compatible models include the Matrix 405, 380, 355, and 310, as well as the Grizzly, GRZ2, and the Bulldog 440, 400, 380, and 330.

It is constructed from BCY DynaFlight 97, a high-performance synthetic material chosen for its minimal stretch. This helps maintain consistent arrow speed and accuracy, meaning you won't have to re-tune your bow as often.

The center serving is the area that takes the most friction from the rail and trigger latch. This proprietary design is built to withstand that wear more effectively than standard servings, significantly extending the overall life of the string.

Yes, it is standard practice to apply a light coat of rail lube or string wax to any new crossbow string before your first shot. This reduces friction and protects the synthetic fibers from premature wear.

While there is no set timeframe, you should inspect your string before every outing for signs of fraying, serving separation, or fuzziness. If you notice any significant wear or if the string has lost its tension, it is time for a replacement to ensure safety and performance.
