Ruger 90723 Ruger-57 Optic Adapter Plate Black Anodized Aluminum

The Ruger 90723 Optic Adapter Plate transforms the Ruger-57 pistol into a red dot-ready platform without requiring slide modifications. This precision-machined mounting solution provides a secure foundation for popular micro red dot sights while maintaining the pistol's original sight picture as a backup.

What Makes This Different

Unlike universal mounting plates that require permanent slide alterations, this factory-designed adapter integrates seamlessly with the Ruger-57's existing sight dovetail. The black anodized aluminum construction resists corrosion and wear while adding minimal weight to the pistol. Precise tolerances ensure consistent zero retention through thousands of rounds and repeated sight removal.

Key Features

• Direct-mount compatibility with Trijicon RMR and similar micro red dot footprints
• Black anodized 6061-T6 aluminum construction for durability and corrosion resistance
• Preserves original iron sight functionality for backup sighting
• Factory-engineered fit eliminates gunsmithing requirements
• Low-profile design maintains holster compatibility
• Precision-machined mounting surfaces ensure consistent optic alignment
• Includes necessary mounting hardware and installation instructions

Field testing demonstrates reliable zero retention across temperature extremes and high round counts. The adapter's rigid mounting system eliminates the flex common in aftermarket solutions, maintaining point of impact consistency during rapid fire sequences. Law enforcement agencies report successful deployment in duty applications where backup iron sights remain critical.
