New for 2024, Leupold’s line of Mark 4HD Riflescopes offer lightweight, durable performance with the outstanding optical quality that all Leupold optics are known for. The Mark4 HD riflescopes are available in 1-4.5x24mm, 2.5-10x24mm, 4.5-18x52mm, 6-24x52mm, and 8-32x56mm variations and come in a wide range of reticle options, making the Mark4 HD series ideal for virtually any application. Each Mark4 HD unit comes with Leupold’s renowned Professional Grade Optical System. This ensures industry-leading glare reduction for a clear image even in harsh direct light, and the resolution and clarity that professional shooters demand in the field. Illuminated versions of the Mark4 HD feature an electronic reticle level that flashes when the scope isn’t level to improve accuracy in long range shots as well as simplifying the mounting process. Illuminated Mark4 HD riflescopes also feature Motion Sensor Technology (MST) that extends battery life by automatically deactivating illuminated reticles after five minutes of inactivity and then reactivates instantly as soon as movement is detected. Additionally, all Mark4 HD riflescopes offer outstanding durability thanks to the use of advanced internal gasses and sealing methods that withstand extreme temperatures, elevation changes, and shocks, so the internals of the optics stay moisture free and crystal clear for life.
