If you are looking to extend your effective range, look no further than the Trophy Ridge React Pro 7 Sight. React Technology accurately predicts what each pin gap will be based on the distance between your 20-yard pin and any other yardage and is effective from 330-270 fps. Once you have two pins sighted-in accurately, the rest of your pins will be automatically set, it's that easy! The React Pro 7 Sight also features 2nd and 3rd axis adjustment and tool-less micro-click windage and elevation adjustments. Thanks to its superior glow-ring, not even low-light conditions can get in your way of a great shot. Impact-armored, ultra-bright fiber optics stay secure and protected. Its 100% aluminum construction and stainless steel hardware guarantee long-lasting performance.
