Description
This titanium-housed pistol optic delivers military-grade durability with versatile reticle options and solar backup power for duty-ready performance.
Whether you’re training hard, competing, or carrying daily, the HE508T X2 eliminates the compromises found in typical pistol optics. Its grade 5 titanium construction provides exceptional strength without excessive weight, while the solar failsafe ensures your sight stays operational even when battery power runs low. The Multi-Reticle System adapts to any shooting scenario—from precision work with the 2 MOA dot to rapid target acquisition using the 32 MOA circle—giving you three reticle configurations in one optic. With Shake Awake technology and side-loading battery access, this sight stays ready while simplifying maintenance.
Key Features
- Grade 5 Titanium Housing: Provides exceptional durability with corrosion resistance suitable for maritime environments while maintaining a lightweight 2-ounce profile
- Multi-Reticle System (MRS): Switch between 2 MOA dot only, 32 MOA circle only, or both combined for versatile sight pictures across all shooting scenarios
- Solar Failsafe Technology: Automatically supplements battery power with solar energy in auto mode, ensuring the sight remains operational even during battery failure when ambient light is available
- Lock Mode with Redesigned Controls: Low-profile buttons prevent accidental setting changes during holstering or handling, with secure lock function for peace of mind
Important Compatibility Notes
- RMR Footprint: Direct compatibility with RMR-cut slides and mounting systems (industry standard footprint)
- Mounting Requirements: Requires either slide milling for the RMR footprint or an adapter plate with optics-ready pistol systems—direct mounting on standard slides is not possible
- Battery Installation: Uses a side-loading CR1632 battery (tray style) for convenient replacement without removing the optic from the firearm
Why We Carry It
The HE508T X2 represents Holosun’s Elite tier engineering, utilizing grade 5 titanium that delivers more than double the tensile strength and five times the fatigue strength of standard 7075 aluminum. This material choice makes the optic suitable even for maritime environments where saltwater corrosion would degrade lesser sights. The X2 generation specifically addresses user feedback from the original 508T by adding redesigned low-profile buttons and Lock Mode functionality, creating a more refined platform for serious use.
Frequently Asked Questions
How do I switch between the different reticle options?
Hold the minus (-) button for three full seconds to cycle through the three reticle configurations: 2 MOA dot with 32 MOA circle, 2 MOA dot only, or 32 MOA circle only. The system requires the full three seconds to prevent accidental changes.
What is the difference between Auto Mode and Manual Mode?
Auto Mode uses the solar panel to automatically adjust brightness based on ambient light while using battery as backup, maximizing battery life. Manual Mode lets you select from 12 brightness settings (10 daylight and 2 night vision compatible) powered solely by the CR1632 battery. You can also activate Lock Mode to secure your settings.
How does Shake Awake extend battery life?
The optic automatically powers down after 10 minutes of inactivity to conserve battery. Any movement instantly reactivates the LED at your last brightness setting, ensuring it’s ready when you need it without manual activation.
