    HOLOSUN HE403B "Shake Awake" Compact Green Dot Sight w/ Low & AR Mount

    The HOLOSUN HE403B-GR Compact Green Dot Sight is built for shooters who prioritize consistent reliability, pinpoint accuracy, and rugged durability. Utilizing Holosun’s advanced Super Green LED technology, this optic boasts an impressive battery life of up to 50,000 hours, ensuring dependable performance regardless of the environment. Its parallax-free design and unlimited eye relief allow for fast target acquisition and effortless aiming.

    A key innovation is the Shake Awake feature, which automatically powers on the sight with any movement and shuts it off after periods of inactivity, thus conserving battery life while keeping the optic ready for action. Additionally, the memory function saves your preferred brightness setting for immediate use in the field.

    With its Super Green LED, the HE403B-GR is up to four times more efficient than traditional red diodes, making it ideal for high-brightness situations. The optic delivers a 2 MOA green dot for precise targeting, complemented by 12 brightness levels (10 for daylight use and 2 for night vision) to adapt seamlessly to any lighting condition.

    Manufactured from precision CNC-machined T6061-T6 aluminum, the sight is engineered to endure harsh environments and severe weather, making it suitable for rifles, shotguns, and crossbows. It offers versatile mounting options with compatibility for both Picatinny and Weaver rails.

    The package includes both a low mount and a 1/3 co-witness (AR) mount, providing flexible installation options—whether you need a discreet, low-profile setup or a configuration that works in tandem with your iron sights.
