The Holosun HS503CU delivers precision targeting with dual reticle options and extended battery life for serious shooters. This compact red dot sight combines a crisp 2 MOA dot with a 65 MOA circle reticle, providing fast target acquisition and precise shot placement on AR-15 platforms and similar firearms.
What Makes This Different
The HS503CU stands apart with its Solar Failsafe technology that extends battery life up to 50,000 hours on setting 6. The multi-reticle system allows instant switching between a 2 MOA dot for precision work, a 65 MOA circle for rapid engagement, or both reticles simultaneously. Unlike basic red dots, this optic maintains zero through temperature extremes and heavy recoil.Key Features
