An excellent addition to an already excellent riflescope, the Leupold Alumina 3 inch-50mm Lens Shade can protect your riflescope’s objective lens from rain, snow and excessive sunlight. These lens covers are compatible with all 50mm objective lens Leupold VX-5HD, VX-6 and VX-6HD models of scopes. These lens covers will also fit other Leupold scopes with 50mm objective lenses that were manufactured after 2004, with only slight variations in overall diameter.
