Shake Awake™

Shake Awake Technology is a standard feature on all current model Holosun optics and serves to extend battery life by deactivating the optic’s LED while not in use. A highly sensitive motion sensor works to detect motion keeping the LED powered on during use. This allows for duty or concealed carry with seamless operation throughout your day or shift. At the end of your day or shift when your firearm is stored, the motion sensor will detect a motionlessness state and after 10 minutes (default setting) Shake Awake Technology powers the LED off until motion is again detected. Shake Awake offers settings from 10 minutes to 12 hours depending on the model and can be deactivated altogether if preferred. The slightest touch of the optic instantly reactivates the LED so your Holosun optic is ready when needed.

The Holosun EPS Core 3 MOA Green Dot EPS-CORE-GR-3 is a compact, enclosed-emitter pistol optic engineered for shooters who demand precision, durability, and reliable performance in a streamlined micro footprint. Designed for concealed carry, duty use, and serious range time, this optic combines advanced technology with rugged construction to deliver dependable results in real-world conditions.

Featuring a crisp 3 MOA green dot reticle, the EPS Core provides an ideal balance between fast target acquisition and refined accuracy. The 3 MOA aiming point allows for precise shot placement at extended distances while remaining highly visible for rapid defensive engagements. Many shooters prefer green reticles for their enhanced visibility in bright daylight and reduced eye strain during prolonged shooting sessions.

The enclosed emitter design protects the internal optical components from dust, lint, moisture, and debris—making it especially well-suited for everyday carry. Unlike open-emitter optics, the EPS Core maintains a clear sight picture even in adverse environments, ensuring consistent reliability when it matters most.

Constructed from durable aluminum, the housing is built to withstand recoil, impact, and daily carry wear without adding unnecessary bulk. The low-profile design supports co-witness capability with compatible iron sights, preserving a dependable backup aiming solution. High-quality multi-coated glass enhances light transmission and clarity, delivering a distortion-free viewing experience.

Holosun’s advanced LED system provides extended battery life for long-term reliability. A convenient side-loading battery tray allows for easy battery replacement without removing the optic, helping maintain zero and minimize downtime.
