The Holosun HE507C-GR-X2 is a premium open reflex sight built for shooters who demand speed, precision, and reliability. Featuring Holosun’s Multi-Reticle System (MRS), users can toggle between a 2 MOA green dot, a 32 MOA circle, or a circle-dot combination for versatile target engagement — from close-quarters speed to precise distance shots. Equipped with Solar Failsafe™ dual power technology, the HE507C-GR-X2 automatically adjusts brightness based on ambient light and draws power from both the sun and its onboard CR1632 battery. Combined with Shake Awake™, the optic stays ready at all times, activating instantly when motion is detected and conserving energy when idle. Constructed from 7075-T6 aluminum and finished with a durable hard anodized coating, the HE507C-GR-X2 is engineered to handle recoil and harsh environments with ease. Its side battery tray allows quick, tool-free replacement without losing zero. With 12 brightness settings (10 daylight, 2 night vision compatible) and up to 50,000 hours of runtime, this optic sets the standard for performance and dependability.
