Holosun EPS Core MRS

• Enclosed emitter design: The sealed emitter stays protected from lint, dust, rain and general carry debris, helping the sight remain usable on defensive handguns and hard-use range pistols where open emitters can be obstructed.
• Multi-Reticle System: The selectable 2 MOA dot, 32 MOA circle, or combined circle-dot lets the sight adapt to fast close-range acquisition or more precise shot placement without changing optics.
• Large window in a compact housing: The 16x23 mm window gives a more open sight picture than many micro pistol dots, making dot pickup easier during the draw while keeping the optic small enough for compact slide setups.
• Long battery runtime: A CR1620 battery with up to 50,000 h of stated life reduces maintenance intervals and makes the sight practical for everyday carry or duty use.
• Rugged aluminum construction: The aluminium housing, together with waterproof, fogproof and shockproof construction, supports reliable use in changing weather, repeated recoil, and daily handling.

About the Holosun EPS Series

The Holosun EPS Series was introduced in 2022 as a family of enclosed-emitter handgun optics built for shooters who want the cleaner maintenance and weather resistance of a sealed design without giving up a low-profile pistol footprint. Within Holosun’s pistol-sight lineup, the series sits as a practical step toward greater durability for concealed carry, duty use, and general handgun shooting, especially where dust, moisture, or clothing lint can affect an open emitter.

Across the range, the series is defined by its enclosed construction and aspheric glass lens, a combination aimed at delivering a clear sight picture while protecting the emitter from contamination. The family includes the full-size EPS and the more compact EPS Carry, covering both larger handguns and slimmer concealed-carry platforms. Depending on model, reticle choices include a single dot or Holosun’s Multi-Reticle System with a 2 MOA dot and 32 MOA circle. EPS models are also associated with practical electronic features such as Shake Awake, and MRS variants add Solar Failsafe, giving the series a strong focus on carry readiness, efficient power management, and fast target acquisition.

About the Holosun EPS Core MRS

The Holosun EPS Core MRS is a compact enclosed reflex sight built for pistol use where reliability, fast presentation, and a protected emitter matter more than extra bulk. Its Shield RMS-C footprint and compact dimensions make it well suited to slim or micro handgun setups, while the enclosed body helps keep the aiming system clear of debris that can collect during concealed carry or outdoor use. The 16x23 mm window gives the shooter a generous viewing area for this size class, which helps the dot appear faster during the draw and supports easier tracking through recoil.

This version uses a Multi reticle configuration with a 2.00 MOA aiming point and selectable reticle modes, giving the sight flexibility for different shooting tasks. A fine central dot supports more deliberate shot placement, while the larger circle pattern can speed up alignment at short range. Adjustable illumination and an intensity switch allow the reticle to be tuned to ambient light, and the sight is described as parallax free, which helps maintain a natural sight picture in rapid shooting positions.

Mechanically, the sight offers 1.5 MOA click adjustments with 30.00 MOA of windage and elevation travel, giving enough adjustment range for typical pistol zeroing. The CR1620 power source and stated 50,000.00 h battery life reduce the need for frequent battery changes, an important advantage on a carry optic. With its 40.00 g weight, aluminium housing, and waterproof, fogproof, and shockproof construction, this Holosun red dot sight is set up for regular carry, training, and defensive handgun use in varied conditions.

About Holosun

Holosun is a California-headquartered optics company focused on sights, lasers, and illumination systems for shooting, hunting, law enforcement, and military applications. The company says it has worked on optics and laser and infrared technologies since 2013, and its product history shows a steady expansion from early red dot sights into pistol optics, laser devices, and other electronic aiming systems.

The brand is closely associated with practical electronic features such as Shake Awake, Solar Failsafe, and the Multi-Reticle System, all of which are relevant to modern red dot sights. Holosun identifies the 403 Series as its starting product line in 2015, followed by products such as the 510C in 2016 and the 507C and 508T pistol sight series in 2017. That development path helps explain Holosun’s strong presence in compact reflex sights and enclosed handgun optics, where battery management, reticle flexibility, and durable electronic design are central to the product category.
