Holosun DRS-TH

The Holosun DRS-TH (Digital Reflex Sight - Thermal) fuses a traditional red dot with a thermal overlay to deliver quick target acquisition in daylight and thermal contrast when conditions demand it. The 256x192 thermal sensor is layered over the optic with multiple fusion modes (white hot, black hot, outline, highlight), and the 1024x768 OLED display keeps the image crisp while you toggle between thermal and standard red dot use. If you do not need thermal, close the front cap and run it like a conventional reflex sight.

Thermal runtime is rated for up to 10 hours on the 18350 battery, while the red dot side delivers long-duration performance for typical carbine use. A 50 FPS refresh rate keeps the overlay usable in motion, and the built-in recording captures what you see without extra hardware. The DRS-TH is heavy compared to traditional red dots, but it consolidates thermal spotting and aiming into a single top-rail optic for users who want an all-in-one solution.
