Ruger 57 Optic Adapter Plate | Burris & Vortex | 90720

The Ruger 57 Optic Adapter Plate allows Ruger-57 owners to mount Burris FastFire and Vortex Viper/Venom micro red dot sights directly to the pistol slide. The plate is precision CNC machined from 6061-T6 aircraft aluminum and finished with a matte black hardcoat anodize for wear resistance. Installation uses the supplied #6-32 screws and follows the sight manufacturer’s mounting specifications; a Torx T-15 wrench is required but not included. Typical applications include everyday carry setups using a micro red dot and precision-oriented range/competition shooting where a low-profile optic footprint is desired.
