Burris Thermal Clip-on Usm C35

The Burris Thermal Clip-on USM C35 is a dedicated thermal imaging attachment designed to transform any traditional riflescope into a full thermal weapon sight system. This clip-on thermal scope delivers genuine night-hunting and low-light tactical capability without requiring a complete optics overhaul, making it an efficient upgrade path for shooters who already have quality daytime glass mounted.

The C35 features 5 color palettes and a 4× power zoom, allowing operators to adapt the thermal image to varying conditions and target contrast scenarios. Integrated stadiametric ranging enables distance estimation without separate rangefinding equipment, while manual and automatic NUC (non-uniformity correction) maintain image clarity across temperature changes. The Hot Track feature isolates and prioritizes warm signatures, critical for detecting game and threats in dense vegetation or complex terrain where thermal contrast is challenging. Weighing 3 pounds with compact dimensions (7.1 × 7 × 12 inches), the unit integrates efficiently with most riflescope configurations while maintaining reasonable balance.

This thermal clip-on serves hunters conducting nighttime predator control, law enforcement operating in zero-visibility conditions, and precision shooters requiring thermal situational awareness. The handheld tracking mode extends utility beyond mounted applications, allowing glassless thermal reconnaissance across property or terrain prior to engagement setup. Its architecture acknowledges the reality that quality riflescopes represent significant investment; the C35 preserves that investment while adding thermal capability that standalone thermal scopes cannot match in daylight precision.

Thermal clip-on technology occupies a distinct niche in the thermal imaging market. Unlike dedicated thermal scopes optimized for night-only use, the Burris C35 integrates with existing daytime optics, preserving reticle familiarity and ballistic zero while adding thermal layering for compound visual and thermal target acquisition. This hybrid approach is particularly valuable in dusk and low-light transitions where thermal advantage peaks but daylight adjustment still matters.
