The Ruger-57 Optic Adapter Plate is a slide-mounted plate built to add red dot compatibility to the Ruger-57 pistol, brand part number 90723. It supports JPoint MRD and Shield RMS red dot sights, and is precision CNC-machined from 6061-T6 aircraft aluminum with a matte black hard coat finish for strength and durability. Installation is straightforward: place the plate on the slide, secure it with the two included #6-32 screws torqued to 30-50 in-lbs using a Torx T-15 wrench, then mount the optic following the sight manufacturer’s own specifications.
