The Holosun SCS MOS Green Dot Optical Sight is a reflex optic engineered for full‑size pistols specifically slide‑cut for the MOS mounting interface. It integrates a direct‑mount footprint with no adapter plate required, a green multi‑reticle system featuring both a 2 MOA dot and a 32 MOA circle, and Holosun’s Solar Failsafe solar‑charging plus internal rechargeable battery architecture. Designed for tactical, competition, or duty use, it offers a low‑profile setup that co‑witnesses with standard‑height iron sights on compatible platforms.
Key Features
Holosun SCS MOS Green Dot Optical Sight: Green reticle featuring a 2 MOA dot, a 32 MOA circle, or both simultaneously, offering flexibility for precision and rapid target acquisition.
Direct‑mount interface: Attaches directly to a pistol slide with MOS cutout; no adapter plate required, which helps reduce added height and improves mechanical interface.
Solar Failsafe™ + internal rechargeable battery: Solar cells feed the internal battery, allowing continuous operation with minimal manual battery changes.
Auto‑brightness with override: Multi‑directional light sensors automatically adjust reticle brightness to ambient lighting; override for high‑brightness mode available when needed.
Low‑profile deck height: Designed to co‑witness with standard‑height iron sights on compatible platforms.
Parallax‑free, unlimited eye relief: Ensures a consistent reticle presentation and allows both‑eyes‑open shooting.
Robust mechanical construction: Titanium (or grade 5 titanium) housing, rated for rugged duty use, plus sealed to IP67/IPX8 for shock, fog and waterproof resistance.
Slim, lightweight design: Weighs approximately 1.3 oz and has a compact footprint suited for pistol‑slide mounting.
Generational Improvements
(This optic represents an evolution in Holosun’s pistol reflex‑optic offerings.)
Improved direct‑mount MOS compatibility compared to earlier models that required adapter plates, thereby reducing height, improving zero retention and simplifying installation.
Adoption of the Solar Failsafe system as the primary power source, reducing dependence on disposable batteries and extending operational readiness.
Enhanced multi‑reticle system (MRS) offering both dot and circle options, whereas earlier models often offered only a fixed dot.
Upgraded housing materials (grade 5 titanium) plus elevated sealing and durability ratings over earlier generations.
Improved automatic brightness control via multi‑directional sensors for better adaptation to lighting environments and improved visibility.
