Holosun HS503CU Red Dot (SKU: 17614)

The Holosun Red Dot HS503CU is a lightweight and compact closed-end red dot sight specifically designed for carbines and automatic shotguns. It is a versatile optic suitable for both daytime and nighttime use in conjunction with night vision devices.

Equipped with a 20mm aperture and a single magnification optical system, this collimator boasts exceptional features. The optics are meticulously designed to achieve zero parallax and provide unlimited eye relief, ensuring excellent accuracy and optimum comfort even for individuals wearing corrective glasses. Furthermore, the lenses are coated with high-transmission anti-reflective coatings, enhancing overall clarity.

The sight displays a 2 MOA target spot within a 65 MOA circle, utilizing an energy-efficient LED diode. This, combined with the Shake Awake automatic wake-up system and an integrated photovoltaic panel, enables the sight to operate for tens of thousands of hours without requiring battery replacement. Additionally, the collimator incorporates an insolation sensor that automatically adjusts the dot's brightness, particularly useful when transitioning between different lighting conditions.

Crafted from a solid block of aluminum, the housing of the Holosun Red Dot HS503CU is finished using the micro-arc anodizing method. With added sealing, it meets the stringent requirements of the IP67 class, ensuring full resistance to adverse weather conditions.
