The ION 1×25 Enclosed Red Dot Sight is built for shooters who demand absolute confidence from their optic, no matter the conditions. Designed around the popular RMSc footprint, the ION delivers premium enclosed-emitter protection, a crisp ultra-bright reticle, and rugged durability in a streamlined form factor built for serious use.

At the core of the ION is the same proven reticle system found in the ATOM, delivering a fast, intuitive sight picture that promotes rapid target acquisition and confident shot placement. Clean, precise, and easy to track, it is designed to perform when speed matters most.

The enclosed emitter design gives the ION a critical advantage in real-world conditions. Rain, snow, dust, and debris are less likely to interfere with the optic’s performance, helping ensure that your aiming point stays visible and your sight stays ready when the environment turns harsh.

Powered by Apex’s exclusive Corona™ LED system, the ION produces an ultra-bright, high-frequency reticle that remains crisp and clearly defined without excessive fringing or starburst distortion. Combined with parallax-free performance and unlimited eye relief, the result is a sight picture that feels fast, natural, and precise from virtually any shooting position.

To maximize efficiency, the ION features the JOLT AWAKE™ Auto Sleep System, conserving battery life during inactivity and instantly reactivating when motion is detected. It is always ready when needed, while delivering long-lasting runtime and dependable performance.

Machined from 7075 aluminum and finished with Type III hard anodizing, the ION is built to take abuse without compromise. It is IP67 waterproof, shockproof to 1500g, and engineered to withstand hard use in demanding environments. The proprietary 7-layer lens coating enhances clarity and light transmission for a clean, bright view in a wide range of lighting conditions.

Compact, durable, and purpose-built, the ION 1×25 delivers enclosed-emitter confidence in a refined, premium optic designed for modern shooters who expect more from every detail.
