Product Overview
HOLOSUN 2-MOA COMPACT GREEN DOT SIGHT – SKU: HE403B-GR
The Holosun HE403B-GR is a compact, lightweight green dot sight built for accuracy, speed, and resilience. Designed to meet the demands of both professional and recreational shooters, it delivers crisp 2 MOA precision in a simple, no-nonsense package that’s ideal for use in Australia’s demanding field conditions.
This optic uses a high-efficiency LED system with a green reticle that remains visible in a wider range of lighting conditions—especially in bright sun—making it a favourite for shooters working under the harsh North Queensland sun. With up to 50,000 hours of battery life on a single CR2032 battery, plus Holosun’s Shake Awake™ technology, it stays ready when you are.
Made from durable 6061-T6 aluminum and fully sealed to IP67 standards, the HE403B-GR is built for reliable performance in wet, dusty, or high-vibration environments.
A reliable companion for rifles, shotguns, or carbines, the HE403B-GR proves that great optics don’t need to be bulky or complicated—just rugged, accurate, and always ready.
