Holosun HE403B: A Reliable and Feature-Packed Optic for Any Shooter

As an avid enthusiast of firearms and optics, I was thrilled to get my hands on the Holosun HE403B. This green dot sight is designed to provide a clear and accurate aiming solution for various shooting disciplines, from hunting to competition. In this review, I’ll share my experience with the HE403B, highlighting its key features, pros, and cons.

Design and Build Quality

The HE403B boasts a rugged and durable construction, with a high-strength aluminum alloy housing that can withstand the elements and rough handling. The sight’s matte black finish helps to reduce glare and provides a non-reflective surface, ideal for stealthy operations or low-light conditions.

Toggle Switch and Runtime

The HE403B features a simple and intuitive toggle switch for power on/off functionality, making it easy to operate even in high-stress situations. The sight’s runtime is impressive, with up to 50,000 hours of continuous use on a single CR123A battery.

Green 2-MOA Dot

The green 2-MOA dot is clear and easy to see, even in low light conditions. The dot’s size and position provide an accurate and stable aiming point for target acquisition. I found the green dot to be particularly effective for fast-paced competitions, where speed and accuracy are paramount.

Elevation and Windage Adjustments

The HE403B features a one-click zeroing system, allowing for quick adjustments to elevation and windage. This makes it easy to tweak the sight’s settings to accommodate different ammunition types, shooting ranges, and environmental conditions.

Here’s a summary of my experience with the HE403B:
