Holosun HE509T-GR X2 Green Dot Sight 2 MOA/32 MOA Multi-Reticle

The Holosun HE509T-GR X2 delivers green dot precision in a titanium housing built for extreme conditions. This enclosed reflex sight combines dual reticle options with Holosun's advanced Solar Failsafe technology for uncompromising reliability.

What Makes This Different

The HE509T-GR X2 features a fully enclosed titanium housing that protects the LED emitter from impact damage and environmental contamination. Unlike open emitter designs, this enclosed system maintains zero even after direct impacts to the lens. The green 2 MOA dot provides 5x better visibility than red dots in bright conditions, while the 32 MOA circle enables rapid target acquisition at close range.

Key Features

• Grade 5 titanium housing withstands 20,000G shock impact
• Green LED emitter with 2 MOA dot and 32 MOA circle reticle options
• Solar Failsafe technology with side-loading CR1632 battery backup
• 12 brightness settings including 2 NV compatible modes
• RMR footprint compatible with standard mounting plates
• IP68 waterproof rating submersible to 5 meters
• Shake Awake motion activation conserves battery life

Field testing demonstrates 50,000+ hour battery life under normal conditions with Solar Failsafe engaged. The titanium construction survives repeated recoil cycles on magnum calibers while maintaining zero retention. Competition shooters benefit from the green dot's enhanced visibility against varied backgrounds, while the circle reticle accelerates close-range engagement times by 30% compared to dot-only systems.
