Description
This solar-powered micro red dot delivers instant target acquisition with dual power sources and up to 50,000 hours of battery life for rifles and carbines.
Never worry about your optic failing at a critical moment. The Holosun HS515CM combines solar technology with battery backup, ensuring your reticle stays illuminated even in challenging conditions. The Multi-Reticle System lets you switch between a precise 2 MOA dot for accuracy or add a 65 MOA circle for rapid close-range engagement—all without re-zeroing. With Shake Awake technology automatically powering on when you need it, this sight is always ready when you reach for your rifle.
Key Features
- Dual Power System: Solar panel with CR2032 battery backup provides up to 50,000 hours of operation on dot-only mode, with solar failsafe keeping the reticle visible even if the battery dies
- Shake Awake Technology: Motion sensor automatically powers the sight on after detecting movement and puts it to sleep after 10 minutes of inactivity, extending battery life while keeping your optic instantly ready
- Switchable Reticle Options: Toggle between 2 MOA dot only for precision shooting or 2 MOA dot with 65 MOA circle for fast target acquisition without affecting your zero
- Military-Grade Construction: CNC-machined 7075-T6 aluminum housing with hard anodized finish and IP68 waterproof rating survives submersion of up to 1.5m depth up to 30 meters
Important Compatibility Notes
- Includes lower 1/3 co-witness quick-detach mount (1.63″ centerline height)
- Uses Aimpoint Micro footprint for aftermarket mount compatibility
- Tool-less side battery access allows battery changes without removing optic from firearm
Why We Carry It
The HS515CM pioneered the integration of solar power technology in micro red dot sights, offering shooters a genuine backup power solution rather than just extended battery life. Holosun introduced this innovation to address a real-world concern among professionals and enthusiasts: optic failure during critical moments. The dual-power system with automatic brightness adjustment means the sight can run indefinitely in adequate lighting conditions, while the battery backup ensures operation in low-light or night vision scenarios. This design philosophy has made Holosun a trusted choice for both recreational shooters and professionals who demand reliability without the premium price tag of legacy brands.
Frequently Asked Questions
How does the solar panel work in low light or indoors?
The solar panel supplements battery power in adequate lighting, but the CR2032 battery automatically takes over in dim conditions. The automatic brightness adjustment detects ambient light levels and switches between solar and battery power seamlessly. In manual mode, you can select from 10 daylight settings and 2 night vision-compatible settings.
Can I use this sight with a magnifier?
Yes, the HS515CM works well with 3x or 5x magnifiers. The lower 1/3 co-witness mount height is compatible with most flip-to-side magnifier mounts. The 2 MOA dot provides sufficient precision for magnified shooting, though you may prefer to disable the 65 MOA circle when using a magnifier for an uncluttered sight picture.
What’s the difference between the HS515CM and HS515GM models?
The HS515CM features solar power backup, while the HS515GM relies solely on battery power with an extended battery life rating. The CM model offers dual power redundancy with solar failsafe technology, making it ideal for extended field use. Both share the same housing design, reticle options, and mounting footprint.
