Holosun HE407C-X3 Green 2 MOA Open Reflex Sight

The 407C is the simple one. Where the 507C gives you a dot, a circle and both, the HE407C-X3 gives you a 2 MOA green dot and nothing to switch. Fewer options means fewer button presses and no chance of ending up on the wrong reticle when it counts. Two MOA is small enough to shoot precisely at distance and still quick to pick up in a slide cut window, and green reads brighter to most eyes than red at the same setting.

The X3 housing reinforces the hood over the window, and the RMR footprint means it drops onto most optics ready slides or an adapter plate without hunting for a match. Automatic brightness with solar failsafe keeps the dot correctly lit as light changes and keeps it running if the CR1632 quits. Shake Awake handles power on its own, with memory and a lockout mode, and the side tray battery swaps without pulling the optic and losing zero.
