Leupold 118768 Alumina Lens Shade 42mm Black Aluminum Screw-On

The Leupold 118768 Alumina Lens Shade eliminates glare and lens flare that can compromise target acquisition in bright conditions. This precision-machined aluminum accessory extends your riflescope's effective range by reducing light interference that degrades image clarity. Built specifically for 42mm objective lenses, it maintains Leupold's reputation for optical excellence.

What Makes This Different

Unlike generic lens shades, the Alumina series features aircraft-grade aluminum construction with a matte black finish that eliminates reflective surfaces. The threaded design creates a secure, wobble-free connection that won't shift under recoil. Standard plastic alternatives crack in temperature extremes, while this aluminum construction handles everything from desert heat to arctic cold without degradation.

Key Features

• Aircraft-grade aluminum construction resists impact and temperature extremes
• 42mm objective lens diameter compatibility with precise threading
• Matte black anodized finish eliminates glare and reflective surfaces
• Screw-on mounting system provides secure, permanent attachment

Field performance shows measurable improvement in target contrast during dawn and dusk hunting periods when side lighting creates the most interference. Competition shooters report clearer sight pictures in variable lighting conditions typical of outdoor ranges. The aluminum construction withstands repeated mounting and removal without thread wear, maintaining tight tolerances season after season. Law enforcement professionals appreciate the non-reflective properties during tactical applications.
