Leupold MARK 3HD 1.5-4X20 illuminated FireDot SPR The Mark 3HD™ was built for any shooter who needs a rugged, precise, and repeatable MIL-based scope for their tactical rifle. The 1.5-4x20mm model provides a wide field of view, while also allowing for precise, close to mid-range shots. Features: - 3:1 zoom ratio: A 3:1 zoom ratio is very common in many scope models. It gives you 3 times more magnification at high power than at low power so you can dial your power down for close encounters or all of the way up for long-range shots. - High-definition, calcium-fluoride lenses ensure incredible clarity at all magnification levels. - This scopes comes with an illuminated reticle, which can help you get on target faster in low-light situations. - Motion Sensor Technology (MST™) extends battery life by automatically deactivating illuminated reticles after five minutes of inactivity and then reactivates instantly as soon as movement is detected. - Leupold pioneered modern waterproof and fogproof technology using 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.
