Fully Enclosed Titanium Construction
The HE509T X2 features a fully enclosed optical system that protects the emitter from environmental interference. Unlike open-emitter reflex sights, the sealed design helps prevent rain, dust, and debris from obstructing the emitter.
Its Grade 5 titanium housing provides excellent strength and durability while maintaining a compact profile. The Flat Dark Earth finish complements FDE firearm configurations.
Green Multi-Reticle System
Holosun’s green Multi-Reticle System offers three selectable reticle configurations:
2 MOA Dot: A fine aiming point for precision.
32 MOA Circle: A large reference for quick visual acquisition.
Circle-Dot Combination: Combines the central dot and outer circle.
The 540nm green Super LED delivers a highly visible aiming point across a variety of lighting conditions.
Solar Failsafe & Shake Awake Technology
The HE509T X2 incorporates two of Holosun’s signature power-management technologies.
Solar Failsafe uses available ambient light to supplement the battery and provide backup illumination when sufficient light is present.
Shake Awake conserves battery life by placing the reticle into sleep mode during inactivity and reactivating it when motion is detected.
Together with its efficient LED system, the optic offers up to 50,000 hours of battery life under specified operating conditions.
Convenient Battery Access & Lockout Mode
A side-loading CR1632 battery tray allows battery replacement without removing the sight from its mount, helping preserve the existing mounting setup.
Lockout Mode prevents accidental changes to the optic’s settings by disabling the adjustment buttons after the desired configuration has been selected.
