Compact, fast, and versatile, the new Leupold Mark 6 offers everything military, law enforcement, and competitive shooters could want in an amazingly small and efficient package. A powerful 6X zoom range yields an expansive field of view and rapid target acquisition at low magnification, and precision long-range target engagements at higher powers. >>Xtended Twilight Lens Coatings >>Places extra emphasis on precisely matching the highest quality coatings to glass indices to achieve the best possible transmission in low-light situations. DiamondCoat 2 provides the best abrasion resistance we’ve ever offered—exceeding even military standards. >>Front Focal Plane Reticles >>The Mark 6 offers a choice of nine front focal plane reticle options.
