DRS Thermal Reflex Sight

Thermal imaging and red dot sights have traditionally meant carrying two separate optics or committing to a dedicated thermal scope. The Holosun DRS-TH changes that equation entirely, packaging both technologies into a single enclosed reflex sight that mounts directly to any Picatinny rail.

At its core sits a 256×192 thermal sensor feeding a high-resolution 1024×768 OLED display at 50 frames per second. The thermal overlay sits behind Holosun's Multi-Reticle System, letting you choose between a precise 2 MOA dot, a fast-acquisition 65 MOA circle, or both together. The same MRS flexibility found across the wider Holosun range. Four thermal palettes (White Hot, Black Hot, Outline, and Highlight) let you tailor the image to suit different terrain, vegetation, and lighting conditions, while selectable 1×, 3×, and 5× digital zoom helps with target identification at longer range.

When thermal capability isn't required, flipping the front lens cap down converts the DRS-TH into a conventional parallax-free reflex sight with unlimited eye relief and over 50,000 hours of battery life from its red dot emitter alone. That dual-purpose design means you aren't sacrificing daytime performance for the sake of night-time capability.

Built-in video and image recording captures thermal footage to onboard storage at the press of a single button, useful for reviewing shot placement or documenting pest control work.

Construction is 7075 T6 aluminium with an anodised finish, rated to IP67 for waterproofing and tested to withstand 1000G of shock. Two rechargeable 18350 lithium-ion batteries power the thermal sensor for up to 10 hours, and a USB charging cable is included.

Windage and elevation adjustments click at 0.5 MOA increments across a ±50 MOA range, giving enough travel for zeroing at practical distances.

An outstanding choice for stalkers, pest controllers, and night shooters who want thermal detection and a capable daytime red dot without switching between optics.
