Holosun 507C-X3 Multi-Reticle Pistol Optic
The Next Generation of the 507C.
The Holosun 507C-X3 takes the proven 507C platform and updates it with a refined housing, modern ergonomics, and the features that have made Holosun one of the most popular choices for pistol-mounted optics.
Built around the widely used RMR footprint, the 507C-X3 provides a low-profile mounting solution for a broad range of full-size pistols and optic-ready platforms. Its rugged 7075-T6 aluminum housing is designed for hard use while maintaining a compact profile suitable for everyday carry, competition, duty, and range use.
The 507C-X3 features Holosun's Multi-Reticle System (MRS), allowing the shooter to select between a precise 2 MOA dot, a fast 32 MOA circle, or the combined circle-dot reticle. Choose your preferred reticle in Red, Green, or Gold.
Choose Your Reticle Color
Red
The classic Holosun configuration featuring a crisp red Multi-Reticle System.
An excellent all-around choice for competition, defensive use, range shooting, and everyday carry.
Model: HS507C-X3-RD
Green
Choose the Green Multi-Reticle System for a bright, high-visibility alternative to the traditional red reticle.
The green version provides the same selectable 2 MOA dot, 32 MOA circle, or combined circle-dot configuration.
Model: HE507C-X3-GR
Gold
The Gold Multi-Reticle System provides a distinctive high-contrast sight picture, particularly against bright or visually complex backgrounds.
Like the Red and Green models, the Gold 507C-X3 allows you to switch between the dot, circle, or circle-dot configuration.
Model: HS507C-X3-GD
Multi-Reticle System
Why choose between a precision dot and a large, fast reticle when you can have both?
The 507C-X3's Multi-Reticle System (MRS) provides three selectable configurations:
- 2 MOA Dot
- 32 MOA Circle
- 2 MOA Dot + 32 MOA Circle
Use the 2 MOA dot when you want a clean, precise aiming point, the 32 MOA circle for rapid visual acquisition, or combine the two for a versatile circle-dot sight picture.
Solar Failsafe™
The 507C-X3 incorporates Holosun's Solar Failsafe™ technology along with a forward-facing light sensor.
The system can use ambient light while automatically responding to changing lighting conditions, providing another layer of redundancy alongside the optic's battery-powered operation.
Shake Awake™
Holosun's Shake Awake™ technology helps conserve battery life by allowing the optic to enter a dormant state when not in use and reactivate when motion is detected.
For a carry, duty, or defensive pistol, that means the optic can remain ready without requiring the shooter to manually turn it on every time the firearm is picked up.
Side-Loading Battery
The 507C-X3 uses a CR1632 battery housed in a convenient side-loading battery tray.
This allows the battery to be replaced without removing the optic from the firearm, helping avoid unnecessary removal and reinstallation.
