The Olight Osight S from Olightstore Usa Inc in Olive Drab Green delivers a compact 1x2 MOA red dot with a 32 MOA circle, housed on an RMSc footprint for versatile mounting on modern receivers and pistols, and built to withstand the rigors of field use with water and weatherproof construction. This optic integrates a magnetic charging cover for convenient upkeep, a shake awake feature and auto sensing to wake the reticle when needed, and a motion sensor that can be toggled on or off to conserve energy. Users can select a multi-reticle system that merges a precision 2 MOA dot with a 32 MOA circle, allowing rapid target acquisition or precise aiming depending on the scenario, while three adjustable brightness levelsdefault, extra bright, and dimmerlet shooters dial in the ideal visibility for varied light conditions. The Osight S runs on a rechargeable Li-ion battery, offers unlimited eye relief, and measures a compact 1.77 inches in length, delivering a reliable balance of speed and accuracy for hunting, range work, or tactical training, all designed to maximize efficiency without complicating your setup.
