Armasight Collector 640 Compact Thermal Weapon Sight - 1-4x25mm, Multi Reticle, 640x480 Resolution, 60Hz, Black

The Armasight Collector 640 Compact Thermal Weapon Sight is a 1-4x25mm thermal optic built for shooters who need reliable heat-signature targeting in total darkness or degraded-light conditions. This compact scope delivers 640x480 thermal resolution at 60Hz refresh rate, giving you a clear, fluid image of your target without ambient light. The multi-reticle system lets you dial in the aiming point that works best for your shooting style, whether you're hunting predators at night, running low-light training drills, or conducting tactical operations where thermal advantage matters.

At 1-4x magnification, the Collector 640 strikes a balance between close-range situational awareness and mid-range precision. The compact 25mm objective keeps the sight lightweight and easy to mount on rifle platforms without excessive weight forward of the action. Thermal imaging cuts through darkness, fog, dust, and heat-distorted air to show living targets that would be invisible to conventional optics—a genuine game-changer for nocturnal hunting or any scenario where you're working without external light sources.

Armasight builds this sight for field use: it's designed to withstand the recoil and environmental stress of active shooting. The thermal core is sealed and nitrogen-purged to handle temperature swings and humidity. Whether you're glassing wide areas or closing in for a precise shot, the Collector 640 gives you the thermal picture you need to make the call, acquire the target, and execute.
