The Random Reviews got a second hand AGM Gen 3 PVS-7 NVG to review. The PVS-7 is proven in combat and beloved for its reliability and comfort. This top-of-the-line system boasts Gen 2+ or Gen 3 intensifier tubes for clear vision in any darkness, plus automatic brightness control and an infrared illuminator for invisible operation. Its tough build lets you handheld or head-mount it, and even add magnification lenses for extra range.
