Slim pistols deserve a serious optic, and the EPS Core Red 3 MOA delivers. Built on the RMSc footprint for subcompact and micro-carry pistols, it brings the wide, full-size lens of the EPS line to a package sized for everyday carry. The enclosed design protects the emitter from dust, debris, and weather, keeping the optic running when an open emitter would be compromised. A forward-facing light sensor automatically adjusts brightness as conditions change, so you always have a clean, readable dot without manual intervention. Shake Awake activates at the slightest movement for instant readiness, and Lockout Mode prevents accidental setting changes during carry. The side-tray CR1620 battery is rated up to 50,000 hours and swaps without a zero reset. Hard-anodized 6061-T6 aluminum housing, IPX8 waterproofing, and a 10,000G vibration rating round out a carry-ready optic built to go where you go.
