Holosun 407C-X3 2 MOA Green Dot Sight - Mini Reflex Sight

100,000 hours of battery life, Solar Failsafe backup, and Shake Awake — on the RMR footprint that fits more slides than any other pattern. The Holosun HE407C-X3 modernizes the proven 407C platform with a reinforced 7075-T6 aluminum housing, side-loading CR1632 battery tray, and a 2 MOA green dot that stays precisely calibrated as light changes through the forward-facing photodiode and Solar Failsafe system.

The Holosun HE407C-X3 is a miniature open reflex pistol sight with a 2 MOA green dot, RMR-pattern footprint, 7075-T6 aluminum housing, IP67 waterproofing, and Solar Failsafe automatic brightness system, designed for everyday carry, duty use, and range performance on RMR-compatible handgun slides.

Four features define the HE407C-X3's carry and duty advantage. The Solar Failsafe system pairs a forward-facing photodiode with solar energy harvesting, automatically adjusting brightness as ambient light changes and maintaining dot function even if the primary battery is depleted — providing a backup power source that most competing micro red dots lack entirely. Shake Awake technology activates the dot instantly when the pistol is moved and enters a low-power sleep state during periods of inactivity, extending the CR1632 battery's rated 100,000-hour lifespan on setting six without requiring the shooter to manage on/off discipline. The RMR footprint provides compatibility with the widest range of optic-ready and milled pistol slides in the market, from production carry pistols to custom-milled competition guns. IP67 waterproofing and 5,000G vibration resistance provide the environmental durability required for a carry optic that may be submerged, dropped, or exposed to sustained recoil without losing zero.
