The Holosun HE403C-GR is a solar and battery powered 20mm micro red dot sight for rifles and carbines, fitted with Holosun’s Green Super LED and a single 2 MOA dot reticle. Holosun describes it as always on and ready: when ambient light is available the Solar Failsafe panel powers the sight even without a battery, and a side-tray CR2032 gives up to 50,000 hours on setting 6 the rest of the time. Shake Awake turns the LED off when the rifle is still and back on at the first movement. The 6061-T6 aluminium housing ships with both a lower 1/3 co-witness mount (1.63 in) and a low mount (0.75 in), so it suits AR-pattern rifles with iron sights as well as low-comb hunting and rimfire rifles.
What is the difference between the HE403C-GR and the HE503CU-GR? The HE403C-GR has a single 2 MOA green dot; the HE503CU-GR adds the Multi-Reticle System with a 65 MOA circle. Both have Solar Failsafe, Shake Awake and the same two mounts.
Does the HE403C-GR work without a battery? Holosun states that with ambient light available the solar panel will power the sight even without a battery; fit the supplied CR2032 for use in low light.
Is it night-vision compatible? Two of the twelve brightness settings are night-vision compatible.
