TD-3C Open Reflex Red Dot Sight

The Hi-Lux TD-3C is a rugged open reflex red dot sight designed for optics-ready pistols, carbines, and shotguns where speed and precision matter most. With a wide 28x19mm viewing window and RMR footprint, the TD-3C delivers rapid target acquisition while maintaining a low profile for faster draws and smoother transitions.

Machined from lightweight yet incredibly strong 7075-T6 aluminum, the TD-3C is built to handle the recoil of full-power handguns and heavy-caliber weapon systems without losing zero. Its reinforced electronic housing protects the emitter from impact, ensuring reliability in both competition and defensive use.

Shooters can quickly cycle between a crisp 3 MOA red dot or a 32 MOA segmented circle-dot reticle, adapting the sight picture for speed, precision, or situational awareness. Each windage and elevation adjustment moves the point of aim in positive 1 MOA clicks, making zeroing fast and intuitive.

With up to 50,000 hours of battery life at medium settings and night vision-compatible low brightness levels, the TD-3C is mission-ready day or night. A side-loading battery compartment allows quick swaps without removing or re-zeroing the optic.
