PixFra Chiron C635F Thermal Clip-On

What it is best for

The Chiron C635F converts your day scope into a thermal sight by mounting in front of it, so you keep your familiar optic, reticle, and zero. It suits hunters who want one rifle for day and night without buying a dedicated thermal scope.

Trade-offs and who it is not for

Clip-on image quality depends on the day scope behind it, and like all clip-ons, it adds weight and length upfront. A dedicated thermal scope can be simpler if you do not need to keep your day optics.
