- MULTI-RETICLE SYSTEM (MRS): Allows selection of a 32 MOA circle with a 2 MOA dot for fast sight picture, or either 2 MOA Dot Only or 32 MOA Circle Only.
- MULTILAYER REFLECTIVE GLASS: Manufactured with optical-quality glass lenses and multilayer coatings for maximum light transmission, wear resistance, reduced glare, and improved battery efficiency.
- SPECIFICATIONS: Reticle: Green 2 MOA Dot & 32 MOA Circle; Light Wavelength: 540nm; Magnification: 1x; Parallax Free & Unlimited Eye Relief; Power Source: Solar & Internal Rechargeable Battery; Brightness Setting: Auto; Housing Material: Titanium; Window Size: 0.58x0.77 inches; Adjustment per Click: 1 MOA; W&E Travel Range: ±30 MOA.
Setup
The SCS-MOS is designed for direct mounting on full-size GLOCK MOS systems, eliminating the need for adapter plates. Ensure your firearm is unloaded and safe before proceeding with installation.
- Verify Compatibility: Confirm your GLOCK model is a full-size MOS variant. This sight is NOT compatible with GLOCK 43X MOS or GLOCK 48 MOS.
- Prepare Slide: Remove any existing optic or cover plate from your GLOCK MOS slide. Clean the mounting surface thoroughly.
- Mount Sight: Align the SCS-MOS sight with the MOS cut on your GLOCK slide. The sight's design features serrated grooves that match the slide for a secure, flush fit.
- Secure Screws: Use the provided screws to firmly attach the sight to the slide. Apply appropriate torque as specified in the detailed user manual (not included in this summary).
- Initial Check: Once mounted, ensure the sight is stable and does not wobble. The low-profile design allows for co-witnessing with standard height iron sights.

Operating Instructions
The SCS-MOS sight is designed for intuitive operation with its solar charging system and Multi-Reticle System.
- Automatic Brightness Adjustment: The sight utilizes multi-directional light sensors to automatically adjust reticle brightness based on ambient light conditions. This ensures optimal visibility in various environments.
- Intensity Override: For situations requiring maximum brightness, the sight features an intensity override function. Refer to the full user manual for specific activation steps, which typically involve a button press to lock the optic into a high brightness mode for 30 minutes.
- Multi-Reticle System (MRS): The MRS allows you to switch between three reticle options: a precise 2 MOA dot, a fast acquisition 32 MOA circle, or both combined. This versatility enables adaptation to different shooting distances and preferences.
- Battery Status: A low power indicator will warn you of low battery days before charging is needed, ensuring you are always aware of your sight's power status.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your HOLOSUN SCS-MOS sight.
- Cleaning the Lenses: Use a soft, lint-free cloth and optical lens cleaner to gently wipe the glass surfaces. Avoid abrasive materials that could scratch the multilayer coatings.
- Housing Care: The titanium housing is highly durable. Wipe it down with a clean cloth to remove dirt, dust, or moisture. Avoid harsh chemicals.
- Solar Panel: Keep the solar charging panel clean and unobstructed to ensure efficient power generation.
- Storage: When not in use, store the sight in a dry, cool place. The internal rechargeable battery maintains charge, but prolonged storage in complete darkness may require exposure to light for recharging.
Troubleshooting
If you encounter issues with your SCS-MOS sight, consider the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Reticle not visible or dim | Insufficient light for solar charging; low internal battery; obstructed solar panel. | Expose the sight to bright light (natural or artificial) for several hours. Ensure the solar panel is clean and unobstructed. |
| Reticle appears distorted or blurry | Dirty lens; astigmatism (user's eye condition). | Clean the lens thoroughly with a soft cloth and optical cleaner. If distortion persists, consult an optometrist. |
| Sight not holding zero | Improper mounting; loose screws. | Re-mount the sight, ensuring screws are tightened to the recommended torque. Check for any movement of the sight on the slide. |
| Low power indicator active | Internal battery charge is low. | Expose the sight to bright light for an extended period to allow the solar charging system to replenish the internal battery. |
