The Holosun EPS CORE RD-MRS brings the wide viewing performance of a full-size EPS lens to a compact RMSc-footprint optic built for slim pistols. Its enclosed design protects the emitter from dust, debris, and weather, while a forward-facing light sensor with Solar Failsafe automatically manages brightness as conditions change. Holosun’s Multi-Reticle System lets shooters choose a 2 MOA dot, a 32 MOA circle, or a combined reticle to match speed or precision needs. Powered by a side-tray CR1620 battery rated up to 50,000 hours and backed by Shake Awake and Lockout Mode, the EPS-CORE-RD-MRS delivers full-size sight picture and modern power management in a carry-ready package.
