Holosun HE403B – GR Green Dot Red Dot Sight

Description

The Holosun HE403B-GR is a 20mm-lens red dot sight designed for rifles and carbines. The HE403B-GR features green LED illumination and a battery life of up to 50,000 hours. The rangefinder has 12 modes (10 daytime and 2 nighttime), is made of T6061 aerospace-grade aluminum, and comes with both low-profile and high-profile mounts in the box. The HR403B-GR has built-in motion sensors (Shake Awake) and a memory function, so even if you forget to turn it off, the speedometer turns itself off after 8 hours, and when touched, it turns on at the last selected dot brightness level. It features LED backlighting and a 2 MOA dot size. It operates on a single CR2032 battery (side-mounted) and comes with protective rubber caps included in the package. HOLOSUN uses exceptionally high-quality lenses, and the brand’s micro-tube models have the largest internal aperture (“field of view”) compared to all similar competing models in their price range.
