The Holosun HE407C-X3-GR introduces a fresh evolution of the 407C platform, combining a reinforced housing, updated branding, and advanced brightness control in a compact optic built for modern pistol setups. Designed from the ground up for today's shooters, the X3 series delivers a low-profile solution optimized for everyday carry, duty use, and consistent range performance. Its crisp 2 MOA green dot provides fast visual pickup with enhanced contrast in bright conditions, giving shooters a clear and confident aiming point. A forward-facing photodiode works in tandem with Solar Failsafe to automatically adjust brightness as lighting changes, while manual brightness control with memory and lockout modes ensures full control when needed. Powered by a CR1632 battery with up to 100,000 hours of runtime on setting six, the HE407C-X3-GR2 is engineered for long-term reliability. Shake Awake technology keeps the optic ready at the first sign of movement, and the rugged 7075-T6 aluminum housing, rated IP67, is built to perform in real-world environments without adding bulk. For shooters who want a modern, carry-ready pistol optic with enhanced visibility and smart power management, the HE407C-X3-GR2 delivers confidence in every draw. a High-visibility 2 MOA green dot for fast visual pickupa RMR footprint compatibility for broad pistol fitmenta Forward-facing photodiode with Solar Failsafe for automatic brightness controla Manual brightness with lockout and memory modesa Eight daylight and four night-vision compatible brightness settingsa CR1632 battery with up to 100,000 hours of runtime on setting sixa Shake Awake technology for instant activationa Low-profile, compact design optimized for carry and holster usea Rugged 7075-T6 aluminum housing with hard-anodized finisha IP67 waterproof rating and 5000G vibration resistancea Parallax-free with unlimited eye relief and multi-coated optics
