The Ruger Max-9 Long Slide Assembly allows for installation of micro red dot optics on MAX-9 pistols. This slide 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. It comes with sights, barrel, extractor and other slide components to simplify installation. Read instructions and warnings carefully before installing and using this slide assembly.
