The Holosun DRS-TH Thermal Fusion Reflex Sight is an innovative optic that combines a traditional red-dot reflex sight with integrated thermal imaging technology. This fusion design allows users to rapidly acquire targets using a red-dot reticle while simultaneously detecting heat signatures through the thermal overlay, making it highly effective for hunting, tactical operations, and low-visibility environments.

Powered by a 256 × 192 thermal sensor and a high-resolution OLED display, the DRS-TH provides clear thermal imagery with smooth performance thanks to a 50 Hz refresh rate. The sight offers several thermal palettes such as white hot, black hot, highlight, outline, and fusion, enabling users to optimize visibility depending on the environment.

The optic also incorporates Holosun’s Multi-Reticle System (MRS) featuring a 2 MOA dot, 65 MOA circle, or circle-dot combination, allowing shooters to adapt their aiming style. With built-in video recording, digital zoom, and rugged waterproof construction, the DRS-TH provides advanced functionality in a compact reflex-style sight designed for modern rifles.
