Holosun Technologies HE510C-GR Reflex Sight

Details
The perfect blend of affordability and reliability, Holosun’s open reflex sight, the HE510C-GR, brings a green reticle to its proven HS510C flagship reflex red dot sight. The green reticle claims to be better perceived by the human eye as opposed to a red dot reticle. In a high brightness setting the green LED reticle provides greater power efficiency than the 510C-GR’s red counterpart.
This reflex sight provides 12 levels adjustable brightness (10 daylight and 2 night vision) for the multi-reticle system. The multi-reticle system offers the choices of a 65 MOA circle or 2 MOA dot or both circle and dot.
The HE510C-GR is equipped with Holosun’s Solar failsafe, on top of Holosun’s stated 50,000 hours of battery life, this reflex sight is also solar powered. The solar failsafe can also automatically change reticle brightness when shifting from dim to brighter environments and from bright to dim environments. The shake awake feature will, at the slightest movement, activate the sight. Shake awake can be deactivated. The mounting system featured is a picatinny rail mount.
