The RNV-31 are compact and adaptable night vision goggles (NVG), engineered for ease of use and flexibility in dim environments. Employing a standard 18mm image intensifier tube, it delivers crisp night vision imagery. Remarkably lightweight at on 17.6 ounces, the RNV-31 ensures comfort during prolonged usage and is well-suited for a multitude of tasks and scenarios.
