Ruger 90318 30mm Medium Height Scope Rings - Silver Finish

The Ruger 90318 30mm scope rings deliver precision mounting for medium-objective scopes on Ruger rifles with integral scope bases. These silver-finished rings provide the optimal height clearance for most hunting and tactical optics while maintaining rock-solid zero retention.

What Makes This Different

Ruger's proprietary ring design features precision-machined steel construction with exact 30mm tube diameter tolerance for secure scope mounting. Unlike generic aftermarket rings, these are engineered specifically for Ruger's integral scope base system, eliminating potential alignment issues. The medium height provides 0.87-inch clearance from base to scope centerline, accommodating most variable power scopes with objective lenses up to 44mm.

Key Features

• Precision-machined steel construction for maximum durability and zero retention
• 30mm tube diameter with exact tolerances for secure optic mounting
• Medium height design provides 0.87-inch scope centerline clearance
• Silver anodized finish matches stainless steel Ruger rifle receivers
• Compatible with Ruger integral scope base system on most centerfire rifles
• Four-screw cap design distributes clamping force evenly around scope tube
• Accommodates objective lenses up to 44mm diameter with proper clearance

These rings excel in hunting applications where reliable zero retention is critical for ethical shots at extended ranges. The steel construction withstands heavy recoil from magnum cartridges while maintaining precise scope alignment. Competition shooters appreciate the consistent return to zero after scope adjustments or rifle transportation.
