Holosun EPS Core Enclosed Pistol Sight - Red 3 MOA Dot

The Holosun EPS-CORE-RD-3 delivers the full-size EPS viewing experience in an RMSc-footprint package with a 3 MOA red dot — the larger lens area of the full EPS in a compact housing that fits the widest range of optic-ready pistols, in a sealed enclosed emitter construction built for daily carry.

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

The EPS-CORE platform's defining characteristic is delivering the full-size EPS lens area in an RMSc footprint — the lens geometry of a larger optic in a compact housing that mounts directly to RMSc-cut slides without an adapter plate. Most enclosed micro optics sacrifice window size for compact dimensions; the EPS-CORE retains the EPS lens shape while fitting within the RMSc footprint boundary. The red 3 MOA red dot provides a clean, high-contrast aiming point suited to a broad range of carry and duty engagement distances. The enclosed emitter keeps the optical path sealed against rain, debris, and sweat exposure — the practical advantage for a daily carry optic. The forward-facing light sensor provides continuous automatic brightness adjustment without manual input. The 6061-T6 aluminum housing keeps added weight to a minimum appropriate for a carry platform. Shake Awake activates on first touch; Lockout Mode prevents accidental brightness changes during carry or holstering.

Reticle: red 3 MOA red dot. Footprint: RMSc. Lens: full-size EPS in RMSc footprint. Battery: CR1620 side-tray, 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 area than standard enclosed micro optics on the same slide cut. Red 3 MOA dot delivers a clean aiming point in a sealed housing. Enclosed emitter protects the optical path from daily carry exposure. 6061-T6 housing minimizes added weight.

The right choice for RMSc-platform pistol users who want enclosed-emitter protection with the largest lens area available in that footprint — red 3 MOA dot in a 6061-T6 housing that fits the broadest optic-ready slide ecosystem.
