The HOLOSUN HE403B "Shake Awake" Compact Green Dot Sight in tan is a robust and very efficient optic designed to meet the demands of shooters who require speed, accuracy, and dependability. It has a clear 2 MOA green dot reticle and provides quick target acquisition with high-precision accuracy in any lighting condition.

Made with heavy-duty CNC-machined T6061-T6 aluminum and an anodized surface treatment, the HE403B is lightweight and strong and can hold up to hard use in the field. The optic is parallax-free and offers infinite eye relief in any shooting position for maximum shooter flexibility.

A notable feature is HOLOSUN's innovative Shake Awake Technology, which powers the sight on automatically with movement and saves power when in standby mode. In conjunction with memory and a CR2032 battery with up to 50,000 hours run time, this optic is ready when you are—without requiring repeated replacement.

The HE403B features 12 brightness levels with 10 daytime and 2 night vision capabilities and is able to adjust with your surrounding with ease. The HE403B offers both AR-height and low mounts to provide platform adaptability.
