Holosun HE503GU-GR Elite Green Circle Dot Sight

  • The Holosun HE503GU-GR Elite Green Circle Dot Sight is a micro green dot optic which can switch between a 65 MOA circle dot reticle and a 2MOA dot only. With Holosun’s Super Green LED technology, the 2 MOA green dot is four times as energy efficient than their standard red dot diode. Perfect for those who have visual trouble with the standard red dot or want to use night vision.

    Also included is Holosun’s Shake Awake technology, so when you grab your firearm, the optic turns on automatically (even the slightest movement will turn it on). There is also an auto-shutoff feature to save battery when no movement is detected for an extended period of time.
