Holosun EPS‑Carry‑GR‑MRS – Compact Closed‑Tube Reflex Sight for Slim Pistols
The Holosun EPS‑Carry‑GR‑MRS is a compact, closed‑tube reflex sight designed for small, slim handguns where a low‑profile, rail‑mounted optic is essential. With overall dimensions of 41 × 27 × 24 mm and a weight of just 28 g, the EPS‑Carry‑GR‑MRS sits very low and adds minimal bulk to the weapon, making it ideal for concealment‑oriented concealed‑carry pistols such as slim subcompact platforms. The 7075‑T6‑aluminum housing is anodized, IPX8‑rated and built to withstand 5000 G of vibration, ensuring reliable performance even under heavy use and strong recoil impulses.
Optically, the EPS‑Carry‑GR‑MRS uses an aspherical glass lens with zero distortion and a 15 × 20 mm viewing window, giving a clear, parallax‑free 1x sight picture that is easy to acquire even from unconventional shooting positions. The green MRS reticle (Multi‑Reticle System) combines a 2 MOA central dot with a 32 MOA outer circle at 540 nm, enabling fast target pickup at close range with the dot and fast follow‑ups at slightly longer distances using the circle. The reticle is illuminated with 12‑level brightness adjustment (8‑level daytime, 4‑level night) plus automatic brightness sensing, so the unit adapts seamlessly to changing light without manual input.

Power comes from a side‑mounted CR1620 lithium cell, which is easy to access and replace, plus an integrated solar panel that works together with Solar‑Failsafe and Shake‑Awake. This configuration extends the estimated runtime to up to 50 000 hours, meaning the EPS‑Carry‑GR‑MRS can remain ready for long periods with minimal battery‑change maintenance. The 1.5‑MOA‑per‑click adjustment with ±30 MOA travel provides precise, repeatable zeroing for compact handgun platforms, and the 13.2 mm height to optical center ensures good compatibility with low‑mount optics and co‑witness setups.

Mounting is optimized for Holosun K pattern machining, with a direct Holosun K base and an included RMSc‑to‑K transition plate so the sight can be installed on a wide range of slim pistols, including common subcompact and micro‑compact service handguns. Order the Holosun EPS‑Carry‑GR‑MRS from Holosun Croatia and integrate a compact, solar‑enhanced green‑dot pistol reflex sight with MRS‑style reticle, 12‑level illumination and 50 000‑hour estimated runtime into your next low‑profile concealed‑carry or sport‑oriented handgun build.

Frequently Asked Questions – Holosun EPS‑Carry‑GR‑MRS
What are the main advantages of the Holosun EPS‑Carry‑GR‑MRS over a basic red dot pistol sight?
The Holosun EPS‑Carry‑GR‑MRS offers a green MRS reticle combining a 2 MOA dot and 32 MOA circle at 540 nm, giving more aiming flexibility than a simple single‑dot red‑dot pistol optic. Its closed‑tube, low‑profile design (41 × 27 × 24 mm, 28 g) and dedicated Holosun K mounting make it highly compact and suitable for slim subcompact handguns, while the 12‑level brightness, automatic light sensing, Solar‑Failsafe and Shake‑Awake significantly extend runtime and reduce the need for frequent battery changes, compared with standard pistol red‑dot sights.
How long does the battery last in the EPS‑Carry‑GR‑MRS?
The Holosun EPS‑Carry‑GR‑MRS runs on a CR1620 lithium battery with an integrated solar panel, offering an estimated up to 50 000 hours of continuous use at the lowest brightness setting. Actual runtime depends on brightness level, usage pattern and ambient light, but the combination of Solar‑Failsafe and Shake‑Awake keeps the unit extremely power‑efficient, making it practical for long‑term use as a concealed‑carry or weekend‑range optic.
Is the EPS‑Carry‑GR‑MRS suitable for compact and subcompact pistols in Europe?
Yes, the EPS‑Carry‑GR‑MRS is specifically designed for compact and subcompact handguns, including slim, pocket‑size service pistols, and is compatible with Holosun K and RMSc‑to‑K patterns, so it fits popular European‑oriented subcompacts. The low 13.2 mm optical height and ultra‑compact 41 × 27 × 24 mm form factor preserve concealability and holster‑friendly dimensions, while the 1x view, MRS reticle and 12‑level illumination make it useful for sport‑shooting sessions and field‑oriented handgun drills.
How durable is the EPS‑Carry‑GR‑MRS on a sidearm mount?
The Holosun EPS‑Carry‑GR‑MRS is built from 7075‑T6 anodized aluminum, rated IPX8 and able to withstand 5000 G of vibration, which is more than enough for the rigors of handgun use. The –30 °C to +60 °C operating range and –40 °C to +70 °C storage range ensure it performs reliably in typical European temperatures. Order the EPS‑Carry‑GR‑MRS from Holosun Croatia and receive a compact pistol reflex sight manufactured to these durability standards with official EU‑based warranty support.
What kind of pistol slides and mounts is the EPS‑Carry‑GR‑MRS compatible with?
The EPS‑Carry‑GR‑MRS features a direct Holosun K base and includes an RMSc‑to‑K transition plate, allowing it to fit a wide range of slim handgun slides, including common subcompacts and micro‑compacts often used in European sport‑shooting. The low‑mount design keeps the optic close to the bore axis, aiding natural pointing and low‑profile holsters. Holosun Croatia supplies the correct hardware and guidance so you can achieve a repeatable, vibration‑resistant zero on your rail‑mounted handgun slide.
Does the EPS‑Carry‑GR‑MRS come with an official EU warranty when purchased from Holosun Croatia?
