The matte black Mark 6 3-18x44mm M5C2 Riflescope from Leupold features a front focal Tremor 3 illuminated reticle and a 34mm tube. The Xtended Twilight Lens System places extra emphasis on matching coatings to glass indices to achieve the transmission of the blue/violet spectrum, without sacrificing the color balanced light transmission across the visual spectrum of the Index Matched Lens System.
The low-profile M5C2 ZeroLock elevation dial automatically locks at the zero position and provides 20 mils of elevation travel in two revolutions of the dial. A visible, tactile revolution indicator provides immediate feedback of the dial position in any lighting conditions.
Exterior lens surfaces are treated with DiamondCoat 2, an ion-assist lens coating, for higher light transmission and an improved level of abrasion resistance.
A 6:1 zoom ratio delivers crystal clear images from edge-to-edge throughout the entire magnification range. The 6X erector system is designed to provide consistently high image quality across the entire visual field throughout the entire zoom range. The Twin Bias Spring Erector System features beryllium/copper alloy leaf springs and 30% more holding force to withstand intense recoil and abuse.
Blackened lens edges reduce unwanted glare and diffusion through the lens edges to provide better resolution, improved contrast, and high optical performance. The riflescope comes with the Argon/Krypton waterproofing and nearly eliminates the effects of thermal shock. The Argon/Krypton molecules also reduce the diffusion of gases sealed inside the scope.
