Leupold Mark 3HD 1.5-4x 20mm Rifle Scope - AR-Ballistic - Leupold has a long history of manufacturing rugged and reliable riflescopes that outperform and outlast everything else on the battlefield and in competition. Leupold used that heritage to create an extremely versatile line of tactical scopes. The Mark 3HD 1.5-4x20mm provides a wide field of view, while also allowing for precise, close to mid-range shots. Complete with MIL-based adjustments and reticles, HD performance, an exposed elevation adjustment dial, and a low-profile power selector with integrated throw lever, the Mark 3HD series is perfect for anyone who needs a rugged, precise, and repeatable scope. Built around Leupold's Elite Optical System, it offers the light transmission, glare reduction, and resolution that diehard hunters and shooters demand for all-day performance. And like every Leupold riflescope, the Mark 3HD was designed, machined, and assembled in the Oregon factory. Leupold tests it to ensure it's absolutely rugged, 100% waterproof and fogproof, and then Leupold guarantees it for a lifetime of performance.
