Holosun EPS Core Enclosed Pistol Sight - Green 3 MOA Dot

The Holosun EPS-CORE-GR-3 delivers the full-size EPS viewing experience in an RMSc-footprint package — the same large lens area as the full EPS in a compact housing that fits the widest range of modern optic-ready pistols, with a green 3 MOA green dot and a CR1620 rated to 50,000 hours.

The Holosun EPS-CORE-GR-3 is a compact enclosed pistol optic in the RMSc footprint, delivering a green 3 MOA green dot through a full-size EPS lens. It features automatic brightness from a forward-facing light sensor, Shake Awake, and Lockout Mode. Battery: CR1620 side-tray, up to 50,000 hours. Housing: 6061-T6 aluminum. Waterproof: IPX8. Vibration: 5000G.

The EPS-CORE's defining characteristic is combining the full-size EPS lens in an RMSc footprint — the lens area of a larger optic in a compact housing that mounts directly to the broadest ecosystem of optic-ready pistol slides without an adapter plate. Most enclosed micro optics sacrifice window size for their compact footprint; the EPS-CORE retains the EPS lens geometry while fitting within the RMSc footprint boundary, providing a larger sight window than comparable enclosed micro optics on the same platform. The 6061-T6 housing provides a weight advantage over 7075 at a modest hardness trade-off — the correct material choice for a carry optic where minimizing added weight is a priority. The Green 3 MOA dot provides a clean, high-contrast aiming point with superior visibility in bright-light conditions and for shooters with red-green color vision deficiency. The forward-facing light sensor provides continuous automatic brightness adjustment without manual input. Shake Awake activates instantly on movement; Lockout Mode prevents accidental brightness changes during carry. Enclosed emitter keeps the optical path sealed against the weather and debris exposure of daily carry and field use.

Reticle: 3 MOA green dot. Footprint: RMSc. Lens: full-size EPS in RMSc footprint. Battery: CR1620, up to 50,000 hours. Features: Shake Awake, Lockout Mode, automatic brightness. Housing: 6061-T6 aluminum. IPX8/5000G.

Full-size EPS lens in RMSc footprint — larger window than comparable enclosed micro optics on the same slide cut. 6061-T6 housing minimizes added carry weight. Green 3 MOA dot delivers high-contrast visibility in bright conditions. Enclosed emitter protects optical path from daily carry exposure.

The right choice for RMSc-platform pistol users who want enclosed-emitter protection and a larger lens window than standard micro optics provide — green 3 MOA dot in a 6061-T6 housing that fits the broadest optic-ready slide ecosystem.
