Find your shot with the all new React® H4™. After only two pin adjustments, React® Technology automatically sights in the remaining pins for dead-center accuracy. Easily make corrections with the advanced tool-less windage and elevation adjustments. Axis adjustments are made via integrated knobs for exacting corrections at your fingertips. Pin adjustments are made using an Allen wrench. This sight is perfect for shooting 195 to 330 feet per second. Take your calibration to the next level with second-axis leveling that allows you to strengthen your accuracy over longer distances. The soft-touch Ballistix CoPolymer® construction reduces vibration and weight. The ultra-bright fiber optic pins and rheostat light maintain your visibility in low and fading light. Enjoy the confidence of unparalleled accuracy at an exceptional value with the all new React H4.
