The Holosun HE403B-GR Elite Green Dot Sight is another high-end collimator made by the American company Holosun. Although the brand has been on the market for a relatively short time, it already enjoys a well-deserved excellent reputation. Holosun is primarily associated with the production of rifle sights, characterized by uncompromising, top-quality workmanship. In its designs, the company often reaches for innovative, cutting-edge technologies, and makes further improvements so that they perform their tasks as well as possible.
Like most Holosun collimators, the Holosun HE403B-GR Elite Green Dot Sight is made from T6061-T6 aluminum. The technology of milling the device from a block of metal provides incredible resistance to mechanical damage. At the same time, the alloy used guarantees very low weight, without excessively increasing the weight of our weapon. The aluminum used for the body of the collimator was additionally covered with a special coating, obtained by anodization. This coating improves the chemical and mechanical resistance of the metal.
The HE403B-GR is the Elite version of the popular Holosun HS403B collimator. The device uses modern Holosun Green Led technology. Thanks to it, the performance compared to the classic red LED is up to four times higher. In addition, the life of a single CR 2032 battery can be as long as 5 years. The use of a highly efficient LED, combined with an optimized control circuit, ensures an operating time of up to fifty thousand (!) hours, at an average brightness setting. The collimator uses lenses made of special glass, dedicated to the production of optics. Their surface is covered with multilayer reflective coatings, which guarantee excellent transmission of visible light, which in turn translates into excellent image quality, which is bright and free of noise.
The Solar Failsafe system, with which the HE403B-GR Elite Green Dot collimator is equipped, allows additional battery savings. In addition, it automatically adjusts the brightness of the aiming point, which is ideal, for example, when moving between open and closed spaces. When switched to manual mode, the user can choose from 10 standard brightness modes and 2 adapted for night vision. The model also features a Shake Awake system for saving batteries. Thanks to it, the collimator automatically goes to sleep after a certain, user-set time. The device then automatically awakens from this mode when the weapon is moved.
The Holosun HE403B-GR Elite Green Dot Sight collimator is a high-end device that will be perfect for dynamic shooting or typical tactical operations, among others. Holosun production sights deservedly enjoy a very good reputation, guaranteeing users the highest quality at a reasonable price. So whether you are training for dynamic shooting, hunting or looking for a collimator for your service weapon, be sure to check out the HE403B-GR Elite Green Dot model from the American brand Holosun.
