Holosun HE407C-X3 Green 2 MOA Dot Reflex Sight with Solar Failsafe and Shake Awake

You draw, the pistol comes up, and the dot needs to be there without a button press. The Holosun HE407C-X3 reflex sight is built for that moment, with a 2 MOA green dot on an open pistol sight that mounts to the RMR footprint.

Shake Awake turns the optic on with movement and lets it rest during inactivity to conserve the CR1632 battery, which is rated for up to 100,000 hours. Auto-Off, Memory and Lockout Mode round out the controls. A forward-facing photodiode handles automatic brightness as light changes, and Solar Failsafe backs it up. You also get manual brightness with 8 daylight and 4 night-vision compatible settings.

The green dot runs at 540 nm through multilayer reflective glass with a 0.91 by 0.63 inch window. The sight is 1x, parallax-free, with unlimited eye relief. Adjustments are 1 MOA per click with plus or minus 50 MOA of windage and elevation travel.

When the battery runs low, the side tray lets you replace it without pulling the optic, so your zero stays put. The black anodized 7075-T6 aluminum housing is IP67 waterproof and rated for 5000G vibration, and the whole Holosun green dot sight weighs 1.5 oz. It is a solid fit for carry, duty and range pistols.
