The React Alpha Bow Sight by Trophy Ridge delivers an innovative design and exclusive features. The .019” single pin features a unique A-shape, which naturally draws your eye to the target without obstructing your view of the vitals. The sight also comes equipped with Trophy Ridge’s advanced React Technology, which automatically sights in the remaining indicators after just 2 yardage adjustments to deliver dead-on accuracy. Adjustments to windage and elevation can be made without the use of tools, and second and third axis leveling allows you to hone your accuracy at longer ranges and extreme angles via the integrated adjustment knobs. In addition, the Alpha React features a rheostat light to adjust the brightness level to fit the environment, and multiple mounting holes allows the sight to be attached in a variety of positions.
