Holosun EPS Core Red Dot Enclosed Pistol Sight 2 MOA Dot & 32 MOA Circle RMSc Footprint Black EPS-CORE-RD-MRS UPC 810047074779

Product Description

The Holosun EPS Core Red Dot Enclosed Pistol Sight (EPS-CORE-RD-MRS) is an ultra-compact, enclosed emitter optic engineered specifically for slimline, concealed carry handguns and optic-ready pistols utilizing the modified RMSc footprint interface. Combining Holosun’s Multi-Reticle System (MRS) with a fully sealed optic chamber, the EPS Core protects the LED light source from rain, dust, mud, lint, and moisture, ensuring an uninterrupted aiming dot in defensive and tactical applications.

Featuring a red LED reticle driver, the EPS-CORE-RD-MRS allows shooters to toggle between a precise 2 MOA center dot, a rapid-acquisition 32 MOA ring, or the combined 2 MOA dot with 32 MOA circle layout. Built with an aluminum housing finished in durable anodized matte black, the sight features a low deck height that enables standard-height iron sights to co-witness cleanly on many slimline pistol slides without necessitating tall suppressor-height sights.

Powered by a side-mounted CR1620 battery providing up to 50,000 hours of continuous runtime, the sight includes Shake Awake technology that automatically sleeps the reticle during inactivity and instantly reactivates it upon sensing movement. Rated IPX8 waterproof and engineered for harsh recoil impulses, the Holosun EPS Core MRS brings enclosed-emitter reliability and multi-reticle versatility to everyday carry pistols.

Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct fitment for modified RMSc / Holosun K-series footprint slides (e.g., Sig P365 series, Springfield Hellcat, Glock 43X/48 MOS via adapter plate, and CZ P-10M). Includes a Holosun K-to-RMR/RMSc conversion adapter plate for broader slide versatility.

Perform a complete firearm safety check: drop the magazine, lock the slide rearward, and visually inspect the chamber to ensure zero live rounds are present.

Clean the optic mounting cut on the slide and inspect the screw hole threads for oil, grease, or threadlocker residue.

Position the EPS Core optic onto the slide's RMSc/K-footprint mounting nubs, ensuring a flush flat seat against the slide deck.

Select the proper length metric mounting screws supplied with the optic. Apply a small drop of medium-strength threadlocker (Blue Loctite 242) to the threads.

Torque the mounting screws evenly in alternating sequence to 15 in-lbs using a calibrated torque tool (do not overtighten).

Install the CR1620 battery into the side battery tray, hand-tighten the tray screw, and perform a function test through all 12 brightness settings and reticle options before live-fire zeroing.
