This is not the first time we have covered a FLIR product. The R-Series scope from FLIR is the world’s first line of thermal night vision rifle scopes starting under $3500.00. You just can’t find another thermal scope in that price point! Unlike your typical night vision scope that detects light the R-Series detects heat energy. That means you could spot a varmint or predator in zero light. The body heat of the intended target will glow bright in the scope. We have included a video for your viewing pleasure.
