Description
This is an enclosed emitter reflex sight engineered specifically for subcompact carry pistols, delivering a protected 2-MOA red dot with unprecedented 50,000-hour battery life.
Switching to a red dot on your carry pistol shouldn’t mean compromising reliability when it matters most. The EPS-CARRY-RD-2 solves the traditional open-emitter problem by fully enclosing the LED and glass, preventing rain, dust, and debris from obscuring your sight picture during critical moments. Its ultra-low deck height allows standard-height iron sights to co-witness on most platforms, while the included RMSc-to-K adapter plate ensures compatibility across multiple subcompact pistol models without requiring custom machining.
Key Features
- Enclosed Emitter Protection: Fully sealed optical chamber prevents water droplets, snow, dust, and lint from interfering with the projected dot, maintaining a clear sight picture in adverse weather conditions
- Extended 50,000-Hour Battery Life: CR1620 battery provides approximately 5 years of continuous operation, with a side-loading battery tray allowing changes without removing the optic from your slide
- Ultra-Low Mounting Height: Lowest deck height in its class facilitates co-witnessing with most factory iron sights, eliminating the need for suppressor-height replacements on many pistol models
- Aspheric Glass Lens System: Optical-quality multicoated glass with aspherical design delivers edge-to-edge clarity without distortion across the entire 0.58×0.77-inch viewing window
Important Compatibility Notes
While the EPS-CARRY-RD-2 works with the included RMSc-to-K adapter plate on most platforms, the following installation considerations apply:
- Sig P365 Series (excluding Fuse/Legion): Direct mounting typically works with included hardware, though some users report better results with platform-specific screws
- Sig P365 Fuse and Legion models: May require alternative screw specifications due to different threading
- Non-MOS Glock 43X/48: Requires slide milling and specific screw lengths for direct mounting without an adapter plate
- Always verify if the extractor plunger moves freely after installation, and apply quality threadlocker to mounting hardware
Why We Carry It
The Holosun EPS Carry RD 2 represents the first generation of truly enclosed-emitter optics optimized for subcompact concealed carry pistols. While Holosun’s open-emitter 507K dominated the micro red dot market for years, real-world testing revealed a persistent vulnerability: water droplets, snow, or debris landing between the emitter and glass could distort or eliminate the dot when you need it most. The enclosed design addresses this fundamental limitation without sacrificing the compact footprint required for daily carry.
Frequently Asked Questions
How does the enclosed emitter design affect battery life compared to open emitter optics?
The EPS-CARRY-RD-2 achieves 50,000 hours of rated battery life using a CR1620 battery, which is comparable to or exceeds many open-emitter designs. The Shake Awake feature automatically powers down the LED after 10 minutes of no motion (adjustable from 10 minutes to 12 hours), extending practical battery life significantly beyond the rated specification. The side-loading battery tray allows replacement without removing the optic from your pistol.
Will this optic require suppressor-height iron sights on my carry gun?
The Holosun EPS Carry Red Dot 2 features the lowest deck height in Holosun’s enclosed pistol sight lineup, designed specifically to co-witness with standard factory-height iron sights on most subcompact platforms, including Sig P365, Springfield Hellcat, and Glock 43X/48 MOS models. The built-in rear notch provides an integrated backup sighting solution. Some shooters prefer suppressor-height front sights for a cleaner lower-third co-witness presentation, but this is optional rather than required.
What’s the difference between the EPS-CARRY-RD-2 and the standard EPS-RD-2?
The EPS Carry is dimensionally smaller and lighter than the standard EPS, specifically optimized for slimline and subcompact pistols. The EPS Carry measures 1.62×1.07×0.95 inches and weighs 1.23 ounces with a 0.58×0.77-inch window, while the full-size EPS features a larger 0.90×0.63-inch viewing window and weighs 1.4 ounces. Both share identical battery life, brightness settings, and the Holosun K footprint, but the Carry version’s reduced profile makes it better suited for concealed carry applications on narrow-frame pistols.
