The all-new Mark 6 1-6x20mm scope was engineered based on the years of elite riflescope making expertise in order to deliver relevant performance features to competition shooters and tactical operators in mid-range to CQB scenarios. Built around a rugged ultra-bright daylight visible illumination system the Mark 6 1-6x20mm offers a true both eyes open situational awareness at 1x while also offering the ability to identify and engage targets out to several hundred meters at high magnification. Several notable mechanical/optical advances include the new low-profile mil-based ZeroLock windage and tactical features that are common throughout Leupold’s Tactical product line. Hands down the most commonly used phrase we hear from tactical end users is “smaller lighter faster when describing the perfect optic. Leupold Tactical Optics; we listened. And delivered. elevation dials to prevent unintentional adjustment in the field and caliber-specific front focal plane reticles. Actual Magnification: 1x - 6x - Linear Field of View (ft/100 yd): 105.8' - 19.3' - Linear Field of View (m/100 m): 35.2m - 6.4m - Eye Relief: 3.7 - Weight: 17 oz - Objective Clear Aperture: 20 mm - Elevation Adjustment Range: 130 moa - Windage Adjustment Range: 130 moa - Xtended Twilight Lens System: Now your hunt can reach further into the twilight than ever before possible with our exclusive new Xtended Twilight Lens System. It goes a step further than even the Index Matched Lens System® using Leupold’s® index matched glass with wavelength specific lens coatings designed to optimize the transmission of low-light wavelengths. When most scope manufacturers quote percentage of light transmission they usually mean at 550 nm the green wavelength where the human eye is most sensitive. The challenge is that in twilight conditions green light disappears and blue/violet light takes over. Your eye is already handicapped when it comes to seeing the blue/violet spectrum and if your scope is cutting too much of it out soon you won’t be seeing anything. The Xtended Twilight Lens System places extra emphasis on matching coatings to glass indices to achieve the best possible transmission of the blue/violet spectrum without sacrificing the color balanced light transmission across the visual spectrum of the Index Matched Lens System. When we combine that with superior computer-generated optical design lead-free lenses of unsurpassed clarity and quality and 100 years of manufacturing excellence you have a scope that gives you the details of low-light scenes in greater definition and luminance than any other scope in the world. DiamondCoat 2: Exterior lens surfaces are treated with DiamondCoat 2 an ion-assist lens coating for higher light transmission and the greatest level of abrasion resistance we’ve ever offered. DiamondCoat already exceeds military standards for hardness and durability. DiamondCoat 2 offers unsurpassed durability and will prove its worth in the wildest places on earth. DiamondCoat 2 has the additional advantage of assisting in light transmission for greater brightness clarity and contrast. Front Focal Plane (FFP): The reticle magnifies along with the image so you can estimate range at all magnification settings. These reticles are ideal in tactical situations yet also provide greater accuracy of range estimation for hunters and target shooters.
