Ruger Ruger-57 Optic Adapter Plate Matte Black for Burris FastFire & Vortex Viper/Venom

The Ruger Ruger-57 Optic Adapter Plate is a precision-machined mounting solution that lets you mount Burris FastFire or Vortex Viper/Venom red dot sights directly to your Ruger-57 pistol slide. If you're running a modern defensive or competition setup and want to add optics to your Ruger-57, this factory-engineered adapter bridges that gap with a rock-solid platform. It's made in the USA from 6061-T6 aircraft aluminum and finished in matte black hardcoat, built tough enough to handle the recoil impulse and stand up to daily carry or range duty.

Installation is straightforward: the plate mounts flush to the slide with two included screws, torqued to spec with a standard Torx wrench. Once secured, your red dot mounts to the adapter using the sight manufacturer's standard procedure—no gunsmithing, no custom drilling. The compact footprint (1.700" long, .975" wide) keeps the overall profile slim, and the negligible weight means zero impact on your gun's handling characteristics.

Whether you're building a duty gun, setting up for competitive shooting, or just want better sight picture on the range, this adapter makes the Ruger-57 a genuine optics-ready platform. It's a genuine Ruger factory accessory, so you know the tolerances are right and the fit is guaranteed.
