Ruger | Ruger-57 Optic Adapter Plate | Black

Ruger's factory Ruger‑5.7 optic adapter plate is precision CNC‑machined from 6061‑T6 aircraft aluminum with a matte black hardcoat finish, built to mount a specific red dot footprint directly and securely to the Ruger‑57's slide. Two #6‑32 screws torqued to spec (30‑50 in‑lbs with a T‑15 Torx) hold it in place, and Ruger offers separate plates for different optic footprints -⁠- Burris/Vortex on one plate, Shield RMS/Sig Romeo/​J‑Point on another -⁠- so you get a purpose‑fit mount rather than a universal compromise. A genuine factory accessory, made in the USA, built specifically around the pistol and optic you're actually running.
