The Leupold 10x50, Tactical Military Binoculars are a high performance, phase coated design with shock-absorbing coyote brown armor and an unexpected twist: a Tactical Milling Reticle(TMR) that can be rotated. The rotating reticle allows users with varying interpupillary distances to view the reticle horizontally so officers can more accurately range an object that is not perfectly horizontal or vertical. Easy to use with eyeglasses or tactical eye protection, the specially coated BAK4 / BK7 prisms virtually eliminate diffraction for added brightness and clarity in all conditions. Well balanced and easy to grip, even with wet hands, they're built rugged and tested to ensure 100 percent waterproof integrity.
