Abstract: A crossbow arrow stabilizer which is designed to stabilize an arrow in loaded configuration in a crossbow and includes an arrow stabilizer block slidably mounted in the stabilizer block housing of the crossbow forestock in concert with a pair of spring blocks carrying spaced, internally-mounted coil springs. The arrow stabilizer block and the spring blocks can be raised in concert against the bias of the coil springs to receive an arrow shaft which is positioned in the forestock between the coil springs, in order to apply pressure on the arrow shaft and align the arrow shaft securely, yet releasably, in the forestock. Release of the bow string by the trigger in the crossbow in conventional fashion forces the arrow from the arrow stabilizer block and allows the arrow stabilizer block to seat on the bottom of the stabilizer block housing by operation of the coil spring.
