InfiRay Outdoor RICO G-LRF 640 3X GH50R Thermal Night Vision Scope


The iRay RICO G-Series 640 has a built-in laser rangefinder. We haven’t ever had a lot of success with rangefinders, whether it be ones that you put on a scope or some other brands, but this scope is dummy-proof. There’s a great picture on this scope in both black hot and white hot, which is an improvement on older RICO models. It’s the best scope available with a built-in rangefinder.



The InfiRay Outdoor RICO G-LRF Series introduces the next generation of thermal functionality, seamlessly combining InfiRay’s industry-leading 12 μm detector technology and a precision laser range-finding module in a single unit. The RICO G-LRF Series features a 1024×768 AMOLED display to guarantee a crisp, high-contrast image, while the precision laser range-finding module ensures accurate measurement to 1000 yards. Additional features include image and video capture with 32GB of storage, wireless streaming, and a field-swappable 26650 battery with a 7-hour run-time.
