With 12 brightness settings, including 10 for daylight and 2 for night vision, the HS503CU adapts to any lighting condition. The Shake Awake technology conserves battery life by activating the sight with motion. Parallax-free with unlimited eye relief, it ensures fast, accurate targeting.
Built from robust 6061 aluminum, the HS503CU withstands tough conditions. It comes with both a lower 1/3 co-witness mount (1.63”) and a low mount (.75”), offering compatibility for rifles with varying comb heights. The side-mounted 2032 battery compartment simplifies battery changes without unmounting the sight.
