The Holosun HE407C-X3-GD2 brings a high-contrast gold 2 MOA dot to the updated 407C-X3 platform, giving shooters faster visual pickup in bright light and against complex backgrounds. Built on the RMR footprint, it pairs a reinforced 7075-T6 aluminum housing with a slim, carry-ready profile for duty use, concealment, and range time. Automatic brightness from a forward-facing photodiode works with Solar Failsafe to keep the dot dialed in as lighting changes, while manual controls with memory and lockout provide full control when needed. Powered by a side-loading CR1632 battery rated up to 100,000 hours and backed by Shake Awake, IP67 waterproofing, and 5000G vibration resistance, the HE407C-X3-GD2 delivers standout visibility without sacrificing reliability.
