This Leupold Tactical Rifle Scope offers an index matched lens system that provides a bright and clear view. The Xtended Twilight Lens System lets you extend your hunt far into the night. Utilizing Wavelength lens coatings which are specifically designed to make low-light wavelengths more visible, the Leupold MK4 lets you see in dim lighting conditions. With a field of view of 11.20 feet by 4.40 feet at 100 yards, distance is no longer a problem for either tactical or hunting use. With a DiamondCoat 2 coating on the lenses and Argon/Krypton waterproofing on the scope itself, the Leupold Mark 4 is an all-weather, shock-resistant addition to your rifle. ** BLEMISHED products may or may not include accessories.
