Holosun 503CU Red Dot Sight for Rifle
The Holosun HS503CU is a micro red dot optic built for rifle and carbine platforms, delivering fast target acquisition and rugged performance in any environment. Featuring a 2 MOA red dot with Holosun’s Multi-Reticle System (MRS), you can switch between a precision dot or a circle-dot configuration depending on your shooting needs. Built from T6061-T6 aluminum, the HS503CU is compact yet tough, ready to handle field abuse and recoil without losing zero. The sight includes Solar Failsafe technology, which powers the optic via ambient light when battery power is low, and Shake Awake, which activates the reticle instantly when motion is detected. Paired with Holosun’s Super LED, the optic offers 12 brightness settings, including 2 night vision-compatible modes, and boasts an impressive battery life of up to 50,000 hours on a single CR2032 battery. The multi-coated lenses ensure optimal light transmission and clarity, while remaining parallax-free and distortion-free. Get yours at NDZ Performance.
