The Ruger M77 1in High Scope Rings, Blued (Ruger part no. 90406) mount directly to the M77’s integral receiver dovetails, so there’s no separate base to buy or install. The raised ring profile clears large-objective rifle scopes up to 52mm in diameter, a step up from Ruger’s medium-height set, while still fitting a standard 1 inch scope tube. The blued finish matches most factory M77 finishes for a clean, factory-correct look.
