The MAX-9 Standard Slide Assembly with ReadyDot Sight allows for installation of micro red dot optics on MAX-9 pistols equipped with a loaded chamber indicator, model 3518. This accessory replaces the pistol's loaded chamber indicator-equipped slide with an optic ready, direct mount slide for co-witnessed JPoint and Shield-pattern micro red dot sights. The Slide Assembly comes equipped with a ReadyDot micro reflex light-gathering fiber optic red dot sight already installed. The Ruger ReadyDot Optic is an easy-to-use micro reflex sight system designed to co-witness on Ruger's MAX-9 pistol. It fits a variety of EDC compact handguns with Shield RMSc footprints and can be co-witnessed to back up iron sights.
