Holosun Elite Green Dot HE403B-GR collimator

The Holosun Elite Green Dot HS403B-GR is an enclosed rifle collimator sight featuring a durable aluminum housing, a Shake Awake battery saving system, and two mounting bases.

Designed for long guns such as AR15 carbines and semi-automatic rifles, this sight offers a lightweight construction. Precision-milled from 6061-T6 aluminum, it has a sturdy yet lightweight design, weighing only 124 g with a high mount. The Holosun Elite Green Dot HS403B-GR is equipped with a "stable zero holding" feature, ensuring there is no parallax error. Its optics provide unlimited eye relief, making it suitable for sporting rifles, AR carbines, and hunting weapons.

The sight utilizes lenses with multi-layer anti-reflective coatings, resulting in high light transmission and a clear, sharp image without parallax error. Its electronic system and diode are designed to be resistant to shock (1000 G), weapon recoil, and adverse weather conditions, ensuring optimal performance on hunting and sporting weapons.

Featuring a 2 MOA green dot aiming point, the Holosun Elite Green Dot HS403B-GR offers a universal and highly visible aiming point. The green LED color provides better contrast against the environment and is less straining to the eyes, making it ideal for prolonged use.

The device boasts an impressive battery runtime of up to 50,000 hours, thanks to the Shake Awake system. This innovative feature automatically turns off the LED when there is no activity, allowing the device to enter sleep mode. Reactivating the aiming mark is as simple as moving the weapon, and the user can define the time interval after which the sleep mode activates.

Battery installation is made convenient with the sliding tray design, secured by two Torx screws. This allows for easy battery replacement without having to remove the collimator from the weapon, distinguishing it from models with batteries located on the underside.

The package includes two Picatinny/Weaver rail mounts: a high mount (1/3 co-witness) primarily for carbines and a low mount recommended for shotguns.
