The Holosun EPS-CORE-MRS is an enclosed optic that pairs a full-size EPS lens with an RMSc footprint for a compact mounting profile. It uses a Multi-Reticle System with a 2 MOA dot, a 32 MOA circle, or a combined reticle, with automatic brightness control supported by Solar Failsafe. Shake Awake with Lockout Mode helps manage power and prevent unintentional setting changes. Powered by a side-tray CR1620 battery rated up to 50,000 hours, it features a 6061-T6 aluminum housing with Super LED and multilayer reflective glass.
