The Holosun EPS Core 3 MOA Red Dot Sight brings an enclosed emitter design to slim pistols while keeping the profile compact and snag free. Built around an RMSc / Holosun K footprint with a full-size EPS viewing lens, it offers a wider, clearer sight picture than typical micro dots. A rugged 6061 aluminum housing with a hard anodized black finish, IPX8 waterproof rating, and 5000G vibration resistance keeps the optic running in demanding everyday carry conditions.

This model’s 3 MOA red dot reticle, automatic brightness sensor, and Shake Awake technology make it well suited for concealed carry, range practice, and general handgun use. The side-loading CR1620 battery delivers up to 50,000 hours of runtime, and Lockout Mode helps prevent accidental brightness changes. For shooters wanting a durable enclosed pistol optic with a clean aiming point and straightforward controls, the EPS Core reflects Holosun’s focus on practical innovation and dependable performance.
