The Steiner MPS Micro Reflex Red Dot Sight is a compact, lightweight pistol red dot built for shooters who demand durability without excess weight. At just 2.05 ounces, this 3 MOA dot sight delivers the optical clarity and ruggedness Steiner is known for in a package small enough to avoid tunnel vision yet tough enough for serious carry and duty use. The MPS fits the ACRO footprint and works with most optic-ready pistols via available adapters, making it a versatile choice whether you're upgrading a modern carry gun or a competition platform.

The sight's all-metal construction and enhanced sidewalls completely seal the laser emitter, creating a water pressure-tight design that performs reliably in any weather. The recessed window with metal hood protects the front lens from snags and impacts—a real-world advantage for daily carry or field use. Eight brightness levels, including two night vision-compatible modes, let you dial in the perfect dot for daylight, low-light, or NV-equipped shooting. A flashing red indicator warns you when the battery is running low, and the 13,000-hour battery life means you'll go years between changes. Best of all, you can swap the CR1632 battery without removing the sight from your gun.

True 1X magnification keeps both eyes open for maximum situational awareness and natural target acquisition. The sight is parallax-free from 10 meters to 150 meters, so your point of aim stays true across practical defensive and hunting distances. Windage and elevation each adjust 90 MOA, giving you plenty of correction range, and each click equals 1 MOA for precise zeroing.
