Holosun EPS Green MRS – 2 MOA Dot & 32 MOA Circle – EPS-GR-MRS

Description

The Holosun EPS Green MRS combines fully enclosed protection with exceptional clarity and flexible reticle options for full-size pistol applications.

Experience worry-free reliability with the EPS Green MRS’s enclosed emitter design that keeps dust, moisture, and debris away from your optic’s critical components. This full-size enclosed pistol sight features Holosun’s Multi-Reticle System with three selectable options—a precise 2 MOA dot, a fast-acquisition 32 MOA circle, or both combined—allowing you to adapt your reticle to any shooting situation. The exceptionally low deck height preserves compatibility with standard-height backup iron sights on many pistol models, while the green 540nm Super LED provides superior visibility that matches the wavelength your eyes detect most easily.

Key Features

• Fully Enclosed Emitter Design: Protects the LED and optic from environmental contamination, including rain, dust, snow, and pocket lint that can compromise open-emitter sights
• Multi-Reticle System Flexibility: Toggle between 2 MOA dot only, 32 MOA circle only, or circle-dot combination by holding the minus button for three seconds
• Ultra-Low Profile Construction: Holosun’s lowest deck height to date allows co-witnessing with factory iron sights on most full-size pistols without requiring suppressor-height replacements
• Solar Failsafe Technology: Dual-power system automatically adjusts brightness in Auto Mode and provides backup operation if the battery fails when light is available

Important Compatibility Notes

The EPS uses Holosun’s K-series footprint and includes an RMR-to-K adapter plate in the box. This is the full-size model designed for standard and compact pistols with wider slides.

• Compatible firearms that may require mounting plates include: Glock 43X/48 MOS (subcompact—consider EPS Carry for better fit), Shadow Systems CR920, PSA Dagger series, Sig P320/M17/M18, Staccato 2011, and others
• The included RMR-to-K adapter plate works with most RMR-pattern cuts but will NOT work with Zev Post slides
• Some “plate sandwich” mounting configurations may require longer screws than provided
• For slimmer subcompact pistols (single-stack or slim double-stack frames), the EPS Carry model offers better proportions while maintaining the same features

Why We Carry It

The EPS represents a significant evolution in pistol optic design by solving the traditional trade-off between durability and size. While enclosed emitters have existed before, they typically required bulkier housings with smaller windows. Holosun’s innovative vertical two-screw mounting system allows the EPS to achieve full enclosure protection while maintaining a large viewing window and the lowest deck height in the Holosun pistol optic lineup. The green reticle wavelength at 540nm is scientifically matched to peak human eye sensitivity, often making it easier to acquire than red dots in bright daylight conditions. This matters during critical moments when split-second target acquisition can make the difference.

Frequently Asked Questions

What’s the advantage of green over red, and will it work with my astigmatism?

Green reticles at 540nm wavelength match the peak sensitivity of human vision, often appearing crisper and brighter in daylight than red dots at equivalent settings. Many shooters with astigmatism report that green dots produce less starburst effect than red, though individual experiences vary. The MRS version’s circle reticle also provides an astigmatism-friendly aiming reference even if the center dot blooms slightly. Set brightness appropriately for ambient conditions—overly bright settings can cause starburst regardless of color.

How does the Multi-Reticle System work, and which setting should I use?

Hold the minus button for three seconds to cycle between three reticle options: 2 MOA dot with 32 MOA circle, 2 MOA dot only, or 32 MOA circle only. The circle-dot combination helps your eye find the aiming point quickly at close range, while the precise center dot enables accurate shots at distance. Many shooters use circle-dot for defensive applications and dot-only for target work. The optic remembers your last setting when it powers back on.

Do I need suppressor-height sights with this optic?

The EPS features Holosun’s lowest deck height, allowing absolute or lower-third co-witness with standard-height factory sights on many full-size pistols when directly mounted to a slide cut. If you’re using the included RMR-to-K adapter plate on top of another mounting plate, the added height may require taller sights. Check your specific pistol and mounting configuration—the goal is to see your front sight in the lower portion of the optic window for backup aiming.
