The Holosun EPS Core (EPSCORERD3) is a compact, enclosed pistol red dot sight purpose-built for carry-ready performance. Featuring a full-size EPS viewing window housed in a slim RMSc-footprint body, this optic delivers a clean 3 MOA red dot with unlimited eye relief and 1x magnification. Its fully enclosed emitter design shields internal components from dust, debris, and harsh weather conditions, ensuring reliable operation under real-world carry and defensive use. A forward-facing ambient light sensor automatically adjusts brightness across 8 daytime and 4 night vision compatible settings, while Shake Awake technology powers the optic on with movement and Lockout Mode prevents accidental adjustment. Powered by a convenient side-loading CR1620 battery rated for up to 50,000 hours of life, the EPS Core offers an outstanding combination of compactness, durability, and long-term readiness in a hard-anodized aluminum chassis.
