LEU MK3 HD 4-12X40 30MM SF TMR We have a long history of manufacturing rugged and reliable riflescopes that outperform and outlast everything else on the battlefield and in competition. We used that heritage to create an extremely versatile line of tactical scopes for the shooter looking to upgrade every long gun in their safe. The Mark 3HD 4-12x40mm model is ideal for mid to long-range shots, making it the perfect scope for nearly any rifle in your safe. 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 our Oregon factory. We test it to ensure it's absolutely rugged, 100% waterproof and fogproof, and then we guarantee it for a lifetime of performance. 3:1 Zoom Ratio Zero Stop Side Focus Custom Dial Compatible Waterproof, Fogproof, & Shockproof
