Ruger 57 Optic Adapter Plate Black Anodized Aluminum Accessory

The Ruger 57 Optic Adapter Plate enables you to mount JPoint MRD and Shield RMS red dot sights on your Ruger 57 pistol. This adapter is precision CNC machined from 6061-T6 aircraft aluminum and finished with a matte black hard coat for strength and durability. Installation is straightforward: place the plate on the slide and secure it with the two provided #6-32 screws. Use a Torx T-15 wrench to tighten the screws firmly to 30-50 in-lbs. (wrench not included). Mount your optic to the adapter plate according to the sight manufacturer’s specifications (sight not included). The package includes extra screws intended for JPoint sight installation only; Shield sights should mount without modification. The adapter plate measures 1.700″ long by .975″ wide and weighs 0.02 ounces.
