Mini-sized closed green dot sight made by Holosun. CNC machined from 7075-T6 aluminum alloy anodized with matte black coating, this mini-sized sight weighs 106g and has dimensions of 69x39x41mm. An IPX8 rating makes it water and shock-proof up to 1000 G. The 20mm lens glass is covered in anti-scratch and reflection multi-coating. 2 MOA green dot and a 65-sized circle with a 1/2 MOA adjustment value is available. An LED provides two NV modes and ten brightness levels. With no parallax, unlimited eye relief, 50 MOA of windage, and elevation regulation, HE515GM-GR guarantees quick and accurate target acquisition in all weather and light conditions. The power is provided by a single CR2032 battery in a cap-secured slot giving it a running time of 50000 hours at a medium dot brightness setting. It also features rubberized controls and a "Shake Awake" system that helps conserve the battery. The set includes a QD mount, flip-up covers, a killflash, a cleaning cloth, and installation keys.
