The Mark 5HD Riflescope by Leupold was designed to meet the demands of hunters and shooters who needed a scope to max out the performance of long-range rifles and ammunition. When compared to riflescopes in a similar class, the Mark 5HD weighs significantly less, making is an excellent choice for professional guides or hunts that require long hikes. The Mark 5HD also comes standard with Leupold’s Professional-Grade Optical System to deliver outstanding light transmission and high-resolution while simultaneously reducing glare. In addition, the Mark 5HD features an exposed elevation turret with large, easy to read numbers and tactile, audible click adjustments. This turret is also protected with a ZeroLock dial, helping prevent accidental adjustments.
