Main Features The best way to get to know the Holosun HS507C-X2 is by learning about its many impressive features. Read on to learn the specifics of what the Holosun HS507C-X2 offers.  Modular Reticle System Like many products by Holosun, the Holosun HS507C-X2 comes with a Multiple Reticle System (MRS.) The MRS is just one of the features that add to this sight's versatility, as it allows you to switch from a 32 MOA circle to a 2 MOA dot or a combination of both. Thanks to those options, the Holosun HS507C-X2 is as useful to hunters as it is to those who short targets or use their firearms in tactical situations.  Three Modes The Holosun HS507C-X2 also comes with three modes for you to choose from. These modes further allow you to customize your experience while using the Holosun HS507C-X2: Auto  Manual  Lock Battery Life One of the more impressive features of the Holosun HS507C-X2 is its battery life. The Holosun HS507C-X2 comes with a CR1632 battery that provides an astounding 50,000-hour battery life when you are using setting six.  Solar Panel Amazingly, the Holosun HS507C-X2 also comes with a built-in solar panel that helps to extend this sight's already impressive battery life. Additionally, the solar panel also supports the auto mode settings of the Holosun HS507C-X2.  Shake Awake While the battery life of the Holosun HS507C-X2 is already impressive, the Shake Awake Technology that this sight includes helps to extend battery life that much more. The highly sensitive motion sensor in this sight can detect slight motions to activate the optics LED when the sight is in use. When the sight is still, indicating non-use, the sensor will deactivate the LED to save energy.  Multi-Layer Reflective Glass The Holosun HS507C-X2 also features multi-layer reflective glass that adds to this sight's performance and durability. Not only does this glass facilitate maximum light transmission, but it also reduces glare and resists wear.  Memory Function Another way the Holosun HS507C-X2 encourages customization is via its memory function. By using this function, you can save your preferences so that the Holosun HS507C-X2 is already set the way you like it every time you use it.  Daylight and Night Vision Settings The Holosun HS507C-X2 also comes with a wide range of settings. Included among these settings are ten daytime settings as well as two night-vision brightness settings. These settings allow for a customized experience whether you use this sight during the day or night. Performance The Holosun HS507C-X2 Classic Multi-Reticle Red Dot Sight sets a new standard in performance, seamlessly blending innovation with precision. Its multi-reticle system offers versatility, allowing users to tailor their sight picture to the situation. With advanced LED technology, the sight provides a crystal-clear view while maintaining an extended battery life.  The solar fail-safe ensures continuous operation in varying lighting conditions, a testament to its reliability. The durable construction withstands the harshest environments, maintaining zero through recoil. Whether for quick target acquisition or precision shooting, the HS507C-X2 delivers unparalleled performance, making it a go-to choice for discerning shooters. Ease of Use One of the most valuable aspects of the Holosun HS507C-X2 is that it is incredibly easy to use. The Holosun HS507C-X2 has an intuitive design that includes simple push-button adjustments on the left side and reticle adjustments on the right side.  Along with that simple design, the features of the Holosun HS507C-X2 provide plenty of customization options. These options not only enhance your experience while using this sight, but they also make the entire process that much more straightforward and intuitive.  In the rare instances in which you'll need to change the battery of this sight, you'll find that the process for doing so is also simple and easy to understand. The same can be said for the reticle sight settings and just about every other feature of the Holosun HS507C-X2. Construction Quality While great design and impressive features are something most people search for in a sight, durability is equally important. Fortunately, the Holosun HS507C-X2 stands as a paragon of field-tested construction.
