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

Precision Performance with Shake Awake Technology

The HOLOSUN HE403B "Shake Awake" Compact Green Dot Sight in Flat Dark Earth is a rugged, high-performance optic designed for fast and accurate target acquisition. Featuring Holosun’s Super Green LED technology, this sight provides a crisp 2 MOA green dot that is up to four times more power-efficient than traditional red dots. With an impressive battery life of up to 50,000 hours on a single CR2032 battery, this optic ensures long-lasting performance without frequent replacements.

Durability Meets Tactical Versatility

Constructed from precision CNC-machined T6061-T6 aluminum, the HE403B is built to handle extreme conditions while maintaining a lightweight profile of just 4.3 ounces. Its parallax-free optical design and unlimited eye relief allow for rapid target acquisition and enhanced accuracy. Shake Awake technology ensures the optic is always ready when you need it, automatically powering on with movement and turning off when idle to conserve battery life.

Ready for Any Setup

The HOLOSUN HE403B comes with both a low-profile mount and a 1/3 co-witness (AR) mount, making it fully compatible with Picatinny and Weaver rails straight out of the box. Its compact design (2.44" x 1.18" x 1.45") integrates seamlessly with a variety of platforms, including airsoft rifles, carbines, and shotguns. Designed for both daytime and nighttime use, this optic features a user-programmable auto-off timer, memory recall for brightness settings, and a durable Flat Dark Earth finish that complements tactical loadouts.
