DESCRIPTION
The Holosun HS503R is a premium red dot sight designed for versatile and reliable performance across various shooting scenarios. Crafted from durable 6061 aluminum, this sight is both lightweight and robust, ensuring long-lasting use. It features rubber lens covers that protect the optics from damage and debris.

The HS503R boasts Holosun’s innovative Multi-Reticle System (MRS), offering shooters the choice between a precise 2 MOA dot, a 65 MOA circle, or a combination of both. This flexibility allows for quick target acquisition and adaptability to different shooting conditions. The sight is equipped with 10 brightness settings for daylight and 2 settings for night vision compatibility, ensuring clear visibility in all lighting environments. Its multilayer reflective glass enhances the clarity and sharpness of the sight picture, providing an excellent visual experience.

A standout feature of the HS503R is its remarkable battery life, powered by a single CR2032 battery. The sight can operate up to 100,000 hours on setting 6, thanks to its efficient power management system. The battery is housed in a user-friendly rotary compartment, allowing for quick and tool-free replacement. Additionally, the sight utilizes a rotary switch for easy adjustment of reticle brightness, ensuring rapid and precise control.

This red dot sight is designed with a parallax-free optical system and unlimited eye relief, allowing for rapid target acquisition and accurate shooting without the need for perfect eye alignment. It is IP67 rated, providing waterproof and dustproof performance to withstand harsh environmental conditions. Compact and lightweight, the HS503R features a 20mm window size and weighs only 3.74 ounces, making it an ideal choice for a variety of firearms.

The HS503R also includes both a lower 1/3 co-witness mount (1.63”) and a low mount (.75”), providing shooters with versatile mounting options to suit their preferences and shooting styles.
