Steiner 1x21 MRS Red Dot Sight (Universal Mounting)

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 custom control. When used with both eyes open, it has an unlimited field of view, exit pupil, and eye relief for maximum situational awareness and maneuverability.

This version of the MRS is made to be used on pistols, shotguns, or long guns not outfitted with standard rail systems, instead it is compatible with most optional rectangular MRDS (micro reflex dot sight) mounting plates using the Burris Fastfire/Docter mount pattern. 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 weighs just 2.5 oz and measures less than 2" long so it is ideal for use on just about any platform without adding excessive bulk or heft.
