Viperlock aluminum shade dart shafts allow proper spacing between flight and barrel which is critical for a smooth trajectory of your darts. They are the optimal shaft to provide balance and stability to your dart’s path to victory. Created from military grade aluminum, these shafts are so durable they can be used night after night. They come with a locking pin and o-rings which allow you to fasten your shafts as tight as possible to prevent them from coming loose and wobbling mid-flight.
