The Ruger 90720 Optic Adapter Plate eliminates mounting complications when installing Burris and Vortex red dot optics on compatible Ruger pistols. This precision-machined aluminum plate creates a secure, stable platform that maintains zero through thousands of rounds.
What Makes This Different
Unlike universal adapter plates that require modification or shimming, the Ruger 90720 features exact specifications engineered specifically for Ruger pistol geometry. The hardcoat anodized finish provides superior corrosion resistance compared to standard Type II anodizing. Machined from 6061-T6 aluminum, this adapter maintains structural integrity under recoil forces that can loosen inferior mounting solutions.
