Ruger ReadyDot Optic Black 1x 15 MOA Red Dot Reticle. It fits a variety of EDC compact handguns with Shield RMSc footprints and can be co-witnessed to back up iron sights. The profile and shape were designed to provide visual guidance for fast target acquisition and EDC capability. The fiber illuminated reticle adjusts to varying light conditions and has been specifically designed for battery-less operation at typical concealed carry pistol ranges. This creates a red dot system that is easier to acquire and stay on target all without worrying about batteries. The 1X reflex sight is fixed in both elevation and windage and the highly visible dot facilitates fast target acquisition. The sight includes a T10 Torx Wrench and (2) M4x0.7 8mm screws for installing the sight on the MAX-9 only. NOTE: The ReadyDot Optic mounts with a standard RMSc footprint. Be aware of differences in screw specifications adaptor plates and mounts between different optics-ready pistols.
