Ruger 90278 4BHM Scope Ring 1" Medium Height Matte Black

The Ruger 90278 4BHM Scope Ring delivers precision mounting for 1-inch scope tubes with medium height clearance. This matte black aluminum ring provides secure optic attachment for Ruger's integrated scope base system. Built to maintain zero through heavy recoil and field conditions.

What Makes This Different

The 4BHM design features Ruger's proprietary mounting system that eliminates the need for separate bases on compatible firearms. Unlike generic rings that require precise torque specifications across multiple screws, this system uses a cam-lock mechanism for consistent clamping pressure. The medium height provides optimal scope positioning while maintaining cheek weld on most rifle stocks.

Key Features

• 1-inch tube diameter with medium height clearance for proper scope positioning
• Aircraft-grade aluminum construction with Type III hard-coat anodizing
• Integrated mounting system compatible with Ruger's scope base receivers
• Matte black finish eliminates glare and resists corrosion
• Precision-machined surfaces ensure consistent scope alignment
• Steel hardware with thread-locking compound pre-applied
• Medium height accommodates objective lenses up to 44mm

Field testing demonstrates reliable zero retention through temperature extremes and repeated firing cycles. The aluminum construction absorbs recoil energy while maintaining structural integrity under magnum cartridge pressures. Hunters appreciate the corrosion-resistant finish during extended exposure to moisture and field conditions.
