Ruger 90275 30mm Extra High Scope Rings Matte Black Finish

The Ruger 90275 scope rings deliver the extra height needed for mounting large objective scopes on rifles with standard rail systems. These 30mm rings eliminate scope-to-barrel interference while maintaining rock-solid zero retention through thousands of rounds.

What Makes This Different

The extra high profile provides 0.97 inches of clearance between the scope tube and rifle barrel, accommodating objective lenses up to 56mm without contact issues. Unlike standard height rings that force compromises in scope selection, these rings open up options for high-magnification optics with large objectives. The precision-machined aluminum construction distributes clamping forces evenly across the scope tube to prevent damage during installation.

Key Features

• 30mm tube diameter fits most modern tactical and hunting scopes
• Extra high profile provides maximum objective lens clearance
• Matte black anodized finish reduces glare and resists corrosion
• Four-screw cap design ensures consistent clamping pressure
• Precision-machined from aircraft-grade aluminum alloy
• Compatible with Weaver and Picatinny rail systems
• Torque specifications marked for proper installation

Field performance depends on proper installation torque and thread locker application. The aluminum construction provides excellent strength-to-weight ratio while the anodized finish withstands harsh hunting conditions and tactical environments. Competitive shooters appreciate the consistent return to zero after scope removal and reinstallation. The extra height proves essential when mounting scopes with 50mm or larger objectives on rifles with heavy barrel profiles.
