Product Description The Holosun EPS-CORE-GD-3 is a compact, fully enclosed red dot sight engineered for pistol carry and competition use. Built on the popular RMSc footprint, it delivers the full-size EPS viewing window in a low-profile package that fits a wide range of micro-optic-ready handguns. The defining feature is its high-contrast 3 MOA gold dot reticle, operating at a 590 nM wavelength, which excels in bright daylight and high-glare environments where standard red dots can wash out. The enclosed emitter housing protects internal electronics from dust, debris, moisture, and the elements, ensuring reliable performance in demanding conditions. A forward-facing light sensor automatically adjusts brightness across 8 daylight and 4 night-vision-compatible settings, while Shake Awake technology powers the optic on with movement and conserves battery life during periods of inactivity. A side-loading CR1620 battery tray allows for quick battery changes without removing the optic from the pistol, and the rated 50,000-hour battery life ensures long-term carry readiness. Lockout Mode prevents unintentional adjustment of settings during use, and the multi-coated lens provides a clear, crisp sight picture at 1x magnification with unlimited eye relief.
