Leupold 51039 Ringmounts 30mm High Matte Black Ruger No.1/77/11

The Leupold 51039 Ringmounts deliver precision scope mounting for Ruger No.1, 77, and 11 rifles with 30mm tubes. These high-profile rings provide the optimal height clearance needed for larger objective lenses while maintaining rock-solid scope alignment.

What Makes This Different

Leupold's proprietary machining process creates rings with tighter tolerances than standard aftermarket options. Each ring maintains concentricity within 0.002 inches, preventing scope tube stress that can affect accuracy. The matte black finish resists glare and corrosion better than basic anodizing, while the steel construction handles recoil forces that aluminum rings cannot withstand.

Key Features

• High-profile design accommodates large objective lenses up to 56mm
• Precision-machined steel construction for maximum durability
• Matte black finish eliminates glare and resists wear
• 30mm tube diameter fits modern tactical and hunting scopes
• Ruger-specific base pattern ensures perfect fit on No.1, 77, and 11 actions
• Windage adjustment capability built into rear ring
• Torque specifications marked for consistent installation

Field testing demonstrates these rings maintain zero through thousands of rounds across various calibers. The high mounting position works particularly well with heavy-barrel rifles where standard rings create clearance issues. Weather exposure from Arctic conditions to desert heat shows no degradation in the finish or mechanical function. Competition shooters rely on the repeatable return-to-zero when removing and reinstalling scopes.
