Ruger 90723 Ruger-57 Optic Adapter Plate for Pistol - Black

The Ruger 90723 optic adapter plate is an OEM Ruger factory accessory engineered to bring pistol-mounted red dot capability to the Ruger-57. If you're running a JPoint MRD or Shield RMS optic and want to eliminate the guesswork of third-party solutions, this precision-machined mounting plate bridges that gap with confidence. Built from 6061-T6 aircraft aluminum with a hard-coat matte black finish, it's built to handle the slide movement and recoil impulse of centerfire pistol shooting without flex or creep.

Installation is straightforward: the adapter sits on your slide and secures with two supplied screws (torqued to 30–50 in-lbs with a T-15 Torx wrench) using standard #6-32 fasteners. From there, your red dot mounts to the plate per the sight manufacturer's specs. The design is compact—1.700" long and 0.975" wide—and adds just 0.2 ounces, so you're not fighting extra weight or bulk when you carry. Because this is genuine Ruger factory engineering, you know the geometry and tolerances will play nice with your Ruger-57 right out of the box.

Whether you're setting up a home-defense pistol, running steel competitions, or just want a cleaner sight picture at the range, a slide-mounted red dot transforms how you shoot. This adapter plate removes the compatibility gamble and puts an OEM solution in your hands. Made in the USA.
