Holosun EPS-CORE Red Dot 3 MOA enclosed reflex sight, black (SKU: EPS-CORE-RD-3 / 48863) is a compact pistol sight with a 23 × 16 mm optical window. The enclosed construction protects the emitter and internal optical components from contamination and moisture. The 1× magnification, unlimited eye relief and lenses with multilayer coatings allow viewing with both eyes open.

The red 3 MOA dot provides a simple and clearly visible reticle. Brightness can be adjusted manually across 12 levels: 8 daylight settings and 4 compatible with night vision devices. Two buttons on the side of the housing provide control. Lock Mode locks the buttons to prevent accidental setting changes.

Power is supplied by a CR1620 battery in a side tray, allowing replacement without removing the sight. The stated battery life is up to 50,000 hours at brightness setting 6. Shake Awake turns off illumination after a period without movement and restores it when motion is detected. The sight retains the last selected brightness level.

The housing is made from 6061-T6 aluminium alloy with a hard anodized finish. The sight has an IPX8 water resistance rating and a stated vibration resistance of 5000 G. The EPS-CORE is compatible with RMSc and Holosun K mounting footprints. Its low base helps keep the iron sights visible, depending on their height and the mounting arrangement used.
