Designed for quick target acquisition and tracking, the Steiner Optic 1x21 MRS Red Dot Sight features anti-reflection multi-coated optics and a 3 MOA red aiming dot that is easy to see in all light conditions without obstructing your target. A built-in light sensor controls the intensity when set to automatic mode, or you can choose one of three manual options for full control. When used with both eyes open, it has an unlimited field of view and eye relief for maximum situational awareness and maneuverability.
Built to hold up to years of use, it has a lightweight aluminum one-piece housing with a corrosion- and scratch-resistant matte-black anodized housing. It is O-ring sealed to make it submersible to 33' for up to 10 minutes. The MRS's compact design and integrated Picatinny/Weaver mount reduces its footprint on rails, while its 2.5-ounce weight helps to lower overall weapon weight versus larger reflex sights.
