Holosun HS515CM Multi-Reticle Red Dot Sight - 2 MOA/65 MOA, 20mm Tube, Black Anodized

The Holosun HS515CM is a compact red dot sight built for shooters who want flexibility without bulk. This 20mm tube optic gives you two reticle options—a crisp 2 MOA dot for precision work and a 65 MOA circle dot for faster target acquisition—switchable on the fly. Whether you're running a pistol, carbine, or shotgun, the HS515CM adapts to your shooting style and lighting conditions.

What sets the HS515CM apart is its dual-power system: Holosun's efficient LED and solar panel design means you can run this sight without a battery in many daylight and mixed-light scenarios. When you do need battery backup, it'll keep the 2 MOA dot alive for up to 5 years, or the circle dot for up to 2 years. No more midnight trips to swap CR2032s if you don't want them. The "U" designation indicates a housing that shrouds the windage and elevation turrets on two sides, protecting your adjustments during the rigors of transport and handling.

The package comes ready to mount and shoot: you get a quick-release mount, flip-up lens covers to keep glass clean between range sessions, and a kill flash filter to suppress reflections on target. The black anodized finish is durable and low-profile, letting your optic work without drawing attention. If you're after a proven, practical red dot that doesn't compromise on features or reliability, the HS515CM delivers Holosun's pedigree in a size that fits most modern setups.

Frequently Asked Questions

Can the HS515CM run without a battery?

Yes. Holosun's solar panels and efficient LEDs allow the sight to operate in daylight and mixed-light conditions without a battery installed. The backup CR2032 battery takes over in low light or darkness, and it'll last up to 5 years on the 2 MOA dot or up to 2 years on the circle dot setting.

What reticles does this red dot offer?

The HS515CM features two switchable reticles: a 2 MOA dot for precision shooting at distance, and a 65 MOA circle dot for rapid target pickup and close-quarters work. You can toggle between them with a button press to match your shooting scenario.

What's included in the box?

The HS515CM ships with a quick-release mount for fast installation and removal, flip-up lens covers to protect the glass, and a kill flash filter to reduce glint. You'll need to supply your own CR2032 battery as backup power.

Will the HS515CM fit my pistol or rifle?

The 20mm tube and quick-release mount make the HS515CM compatible with most modern slide-milled pistols and AR-height rails. Verify your platform's mounting interface before ordering to ensure proper fit.
