Key Features and Benefits

Large Field of View with Multi-Coated Lens

Engineered with advanced anti-reflective lens coatings to maximize light transmission and reduce glare, delivering outstanding clarity and crisp sight pictures. The generous 0.95″ × 0.75″ viewing window provides an expanded field of view for faster target acquisition and quicker follow-up shots.

Side-Loading Battery Design

Effortless battery replacement without removing the optic from the slide helps preserve zero. Powered by a CR1632 battery, the side-access compartment ensures convenient changes while maintaining consistent performance.

3 MOA Dot + 32 MOA Circle Reticle System

Switch between dot-and-circle, dot-only, or circle-only reticles to match your shooting style and application. The sharp 3 MOA dot delivers precision aiming, while the 32 MOA circle enhances rapid target engagement at close distances.

Most Common Footprint Compatibility

Adopts the de facto industry standard Ruggedized Miniature Reflex footprint (commonly known as 407c/507c pattern), making it compatible with many optics-ready full-size and compact pistols. Optional Picatinny mounts in both high and low configurations expand compatibility to a wide range of rifle platforms.

Motion Sensor Activation

Integrated motion sensor automatically activates the optic at the slightest movement and powers down after 3 minutes of inactivity to conserve battery life, ensuring the sight is ready when you are.
