Holosun 515CM

The Holosun 515CM is a hard-use enclosed rifle optic available with either a red or green Multi-Reticle System. Select the preferred reticle color from the available options above. Both configurations combine a compact 20mm sight window, Solar Failsafe, Shake Awake, protective lens covers, and a quick-detach lower 1/3 co-witness mount for rifles, carbines, and pistol-caliber carbines.

Holosun’s Multi-Reticle System allows the shooter to choose between a precise 2 MOA dot or a 2 MOA dot surrounded by a 65 MOA circle. The uncluttered dot supports deliberate aiming and increased precision, while the circle-dot configuration provides a larger visual reference for rapid acquisition, close-range engagements, and faster target transitions.

The Red model uses a 650nm Super LED, while the Green model uses a high-visibility 540nm Super LED. Both versions provide 12 brightness settings, including two settings compatible with night-vision equipment, and deliver up to 50,000 hours of battery life at setting six.

Solar Failsafe supplements the CR2032 battery with available ambient light and supports automatic reticle-brightness adjustment when the optic is used in Auto Mode. Manual Mode gives the shooter direct control over reticle intensity for consistent visibility across changing environments.

Shake Awake conserves battery life by placing the optic into standby after a period of inactivity. Movement immediately restores the reticle at the previously selected setting, helping keep the sight ready without requiring the shooter to manually reactivate it.

A tool-free side battery tray allows the CR2032 battery to be replaced without removing the sight from the firearm or disturbing its zero. Lockout Mode helps prevent accidental button presses from changing the selected brightness or operating mode.

The Holosun 515CM includes clear, removable, and rotating lens caps that protect the optical surfaces from dust, moisture, and debris. A removable kill flash further reduces glare and visible reflections from the objective lens while adding another layer of protection during demanding use.

Its rugged aluminum housing is rated IP68 for resistance to water and dust. The included quick-detach Picatinny mount positions the optic at a 1.63-inch lower 1/3 co-witness height and allows rapid removal or installation without separate tools.
