Holosun HE403R-GD Gold Dot collimator low mount

The Holosun HE403R-GD Gold Dot is an advanced collimator sight designed for use on long guns, such as AR15 carbines and semi-automatic rifles. With its gold-colored target mark and innovative features, this sight offers exceptional performance and versatility.

Crafted from precision-milled 6061-T6 aluminum, the HE403R-GD Gold Dot boasts a sturdy yet lightweight design, weighing just 173 g with a 1/3 Co-witness mount. Its "stable zero holding" feature ensures reliable accuracy, while the absence of parallax error and unlimited eye relief make it suitable for various applications, including sporting rifles, AR carbines, and hunting weapons. The collimator utilizes lenses with multi-layer anti-reflective coatings, providing high light transmission and a clear, parallax-free image. Built to withstand 1000 g overload, weapon recoil, and challenging weather conditions, this device is reliable and efficient in any situation.

Setting itself apart from traditional red and green dot sights, the HE403R-GD Gold Dot employs a 2 MOA dot aiming point displayed in a striking gold color. This unique choice offers several advantages, including enhanced visibility for individuals with color blindness, improved target identification on yellow and green backgrounds, and easier differentiation from laser target indicators.

The power supply of this collimator sight relies on a single CR2032 battery, conveniently located under the outer cover. Thanks to the Shake Awake system, the sight boasts an impressive battery life of up to 100,000 hours. This intelligent feature automatically turns off the LED when there is no motion activity, conserving power. Reactivating the aiming mark is as simple as moving the weapon, ensuring quick and effortless operation. Users can customize the sleep mode activation time according to their preferences. The aiming mark adjustment reels offer precise 0.5 MOA clicks and a generous offset range of 50 MOA vertically and horizontally.

Included with the sight are two Picatinny/Weaver rail mounts. The high mount (1/3 co-witness) is primarily designed for carbines, while the low mount is recommended for shotguns, catering to different firearm setups.
