The 3 fixed pin plus 1 hybrid-floating pin sight allows the hunter to dial his distance to the exact yard in a matter of seconds. This eliminates the guesswork when shooting extended ranges - delivering optimum precision in the field. The Optix XRs floating pin is assembled under tension removing all possible noise and vibration. Using patented Smart Pin Technology, the Optix XR allows the hunter to precisely adjust each individual pin without the pin ever deviating from the centerline of sight.
