The Mark 5HD 2-10x30mm exemplifies military tradition. Created as an evolution of the riflescopes used on the MK12 SPR, this modern optic extends the limits of tactical carbines. A three-turn dial crowns its elevation turret, providing 34.9 MILs of adjustment in 0.1 MIL increments, and our patented ZeroLock ensures the dial won't move when knocked around. This mid-range scope is as bomb-proof as it gets, but it's also incredibly lightweight and accurate. With its first focal plane reticle, 2-10 magnification range, and side focus, engaging in close-quarters combat is just as easy as identifying threats from a distance.Built around Leupold's Professional-Grade Optical System, the Mark 5HD offers unmatched light transmission that's designed to outperform in the most challenging lighting conditions. Its industry leading glare reduction provides a clear image in harsh, direct light, while the resolution and clarity will meet the demands of any professional guide or shooter. Ergonomically designed with more tactile and audible click adjustments, larger numbers, and a high-speed throw lever, the Mark 5HD is built to put accurate fire downrange faster.The unique combination of features, durability, and professional-grade optical performance guarantees that the Mark 5HD can handle any challenge you throw at it. It's 100% waterproof and fogproof, and like all Leupold riflescopes, it's designed, machined, and assembled in the USA and guaranteed to perform for life.
