Holosun

The Holosun 403B Reflex Sight offers reliable performance in a compact and durable package, making it suitable for a variety of firearms, including shotguns, pistols, air rifles, and crossbows.

Featuring a 2 MOA green dot reticle, the 403B provides a precise aiming point for both day and night use. Its parallax-free design ensures that the reticle remains on target regardless of eye position, while its durable aluminum housing and matte finish offer resistance to wear and extreme weather conditions.

This longevity is further enhanced by the optic's Shake Awake technology, which activates the sight with the slightest movement, conserving battery power during periods of inactivity.

With its small and lightweight design, the 403B is easy to mount on a variety of firearms using standard mounts. Whether for recreational shooting, hunting, or tactical applications, this reflex sight offers reliable performance and durability in a compact package.
