Holosun SCS-MOS Solar 2 MOA Green Dot is a direct-mount pistol optic engineered specifically for full-size GLOCK MOS slides, eliminating the added height and potential loosening points of adapter plates. With an ultra-compact 1.93×1.03×0.91 in footprint and just 1.3 oz of weight, it keeps your presentation fast while giving you a clear 0.58×0.77 in viewing window for rapid dot acquisition. Its solar charging system with multi-directional light sensors automatically manages brightness as lighting changes, reducing the need to constantly adjust settings when moving from indoor to outdoor environments. The 2 MOA green dot provides a crisp aiming point for precision, while 1 MOA-per-click adjustments and a ±30 MOA windage/elevation range let you zero confidently and maintain repeatability. Built with a titanium housing and titanium finish, the SCS-MOS is designed for hard use, backed by IP68 submersion protection and wide operating temperatures from -30℃ to 60℃ (storage -40℃ to 70℃). For duty carry, range work, or defensive setups on a Glock MOS, this Holosun green dot sight delivers a low-profile, slide-ready solution from a brand known for rugged reflex optics.
