Micro-sized open red dot sight made by Holosun. CNC machined from 7075 aluminum alloy anodized with matte black coating, this micro-sized sight weighs 30g and has dimensions of 45.7x30.5x40.5mm. An IP67 rating makes it water and dust resistant as well as shock-proof. The 23x16mm lens glass is covered in anti-scratch and reflection multi-coating. 2 MOA-sized red dot and a 32-sized circle with a 1/2 MOA adjustment value is available. An LED provides two NV modes and ten brightness levels. With no parallax and unlimited eye relief, HS407C X2 guarantees quick and accurate target acquisition in all weather and light conditions. The power is provided by a single CR1632 battery in a screw-secured tray giving it a running time of 50000 hours at a medium brightness setting. It also features rubberized controls and a "Shake Awake" system that helps conserve the battery. The solar panel on top with the incorporated "Solar Failsafe" system amplifies the brightness settings. The set includes a universal key, a cleaning cloth, and an installation set.
