Holosun EPS Full Size 6 MOA Red — Enclosed Reflex Pistol Sight
Holosun · Enclosed Pistol Sight
The Holosun EPS (EPS-RD-6) is a full-size, fully enclosed pistol red dot that seals the emitter and lens against dust, lint, rain, and debris — the durability edge of an enclosed optic in a duty- and carry-ready package. A bold 6 MOA red dot, aspheric multi-coated lens, and 7075 aluminum body make it a rugged everyday choice.

Why an Enclosed Emitter?
An enclosed emitter seals the LED and lens inside the housing, so the things that blind an open reflex — lint, rain, snow, dust, holster debris — can’t reach the emitter:
- Sealed emitter — no open channel for debris to block the dot.
- IPX8 waterproof and 5000G vibration resistant.
- K footprint — includes an RMR-to-K adapter plate for broad slide compatibility.
- Ultra-low deck — co-witnesses with most factory iron sights.
