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 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 elevation dials that prevent unintentional adjustment in the field and caliber-specific front focal plane reticles. 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.
