Product description
Full-Size EPS Viewing Window in a Compact RMSc Enclosed Optic
Features
- Enclosed emitter design protects the LED from dust, debris, and moisture
- 3 MOA red dot provides a simple aiming point without an additional circle reticle
- Full-size EPS viewing window provides a larger sight picture while retaining a compact RMSc mounting footprint
- Forward-facing light sensor adjusts reticle output for changing lighting conditions
- Shake Awake activates the optic when movement is detected and powers it down when idle to preserve battery life
- Eight daylight and four night-vision-compatible brightness settings provide manual adjustment when needed
- Lockout Mode helps prevent accidental button presses and unwanted setting changes
- Side-loading CR1620 battery tray allows battery replacement without removing the optic
- 6061 aluminum housing features a hard-anodized finish, IPX8 water resistance, and 5000G vibration resistance
The Holosun EPS Core pairs the larger viewing window of the full-size EPS with an RMSc-footprint housing sized for compact pistol applications. Its enclosed emitter keeps contaminants away from the LED, while the 3 MOA red dot, Shake Awake system, side-loading battery, and multiple brightness settings keep operation simple and easy to maintain. The 6061 aluminum housing weighs just 1.4 oz while retaining Holosun’s IPX8 sealing and 5000G vibration rating.
Note: RMSc footprint compatibility does not guarantee direct installation on every handgun. Verify the slide cut, mounting plate, screw length, and hardware requirements for the specific pistol before installation.
