Holosun HE509T-RD X2 Red Dot Sight 2 MOA/32 MOA Circle Reticle

The Holosun HE509T-RD X2 delivers titanium housing durability with advanced Solar Failsafe technology for mission-critical applications. This enclosed red dot sight combines precision optics with multiple power sources to maintain zero under extreme conditions.

What Makes This Different

The titanium construction provides exceptional impact resistance while maintaining a lightweight 1.78 oz profile. Solar Failsafe technology automatically switches between solar power, internal battery, and backup battery to ensure 50,000+ hours of operation. The enclosed design protects the LED emitter from debris and moisture that can compromise open-style red dots.

Key Features

• Grade 5 titanium housing rated for .50 BMG recoil forces
• Multi-Reticle System with 2 MOA dot, 32 MOA circle, or combination modes
• Solar Failsafe with CR1632 battery providing 50,000+ hour runtime
• 12 brightness settings including 2 NV-compatible modes
• RMR footprint compatible with standard mounting plates
• IP67 waterproof rating for submersion up to 1 meter
• Shake Awake technology activates sight from motion detection

Field testing demonstrates consistent zero retention through temperature extremes from -4°F to 140°F. The 1x magnification provides unlimited eye relief for rapid target acquisition in competitive shooting and tactical applications. Parallax-free design maintains point of impact accuracy regardless of eye position behind the optic.
