Holosun 407C X2 The 407C X2 shares many features with its counterpart but has a simpler reticle system. It offers only a 2 MOA dot, which some shooters prefer for its simplicity and precision. Like the 507C X2, the 407C X2 has the same housing and window size. It also includes features such as auto brightness, shake awake, and solar failsafe. The 407C X2 is often chosen by those who prefer a straightforward dot sight without additional reticle options. It maintains the same durability and battery life as the 507C X2. Both sights use the RMR footprint, making them compatible with many popular handgun models and mounting systems. Optical Features The Holosun 507C X2 and 407C X2 offer different reticle options and brightness settings. These features impact sight picture and usability in various conditions. Reticle Patterns The Holosun 507C X2 has a multi-reticle system with three options: a 2 MOA dot, a 32 MOA circle, and a combination of both. This versatility allows users to choose the best reticle for their needs. The 407C X2 comes with a single 2 MOA dot reticle. This simpler design may be preferred by shooters who want a clean, uncluttered sight picture. Both models use crisp, clear LED projections for their reticles. The precise dot size helps with accuracy at various distances. Brightness Settings Both the 507C X2 and 407C X2 feature multiple brightness settings. Users can adjust the reticle brightness manually or use the auto-brightness function. The auto-brightness mode uses a light sensor to adapt the reticle intensity to ambient light conditions. This helps maintain visibility in changing environments. Manual adjustment allows for fine-tuning to personal preferences. Both models offer a wide range of brightness levels, from very dim for low-light use to bright settings for sunny days. The optics include a solar failsafe feature, which can power the reticle using ambient light if the battery fails. This adds an extra layer of reliability to both models.
