The Holosun IRIS-GR3 Green is a compact, high-end multi-function laser and IR illuminator unit built for serious rifle setups. It combines a visible green laser for daytime aiming, an IR laser for night vision use, and a powerful VCSEL IR illuminator that helps you actually see and identify targets under nods instead of just aiming at shapes. It’s built from lightweight 7075-T6 aluminum and sits lower and slimmer than older Holosun laser units, so it doesn’t take over your rail. You also get co-aligned lasers for easier zeroing and a top-mounted adjuster that lets you quickly switch the IR beam from flood to spot depending on distance. In short, it’s a compact but very capable all-in-one aiming and night vision support system for rifle users who want full functionality without extra bulk.

DESCRIPTION

The Holosun IRIS-GR3 is a professional-grade, triple-function laser and IR illumination system designed for users who demand maximum performance from the smallest possible footprint. Engineered from high-strength 7075-T6 aluminium, the redesigned housing is 43% lighter and 20% lower than the LS321 series, offering a compact, ergonomic, and highly durable platform suited to modern carbines, SBRs, PDWs, and tactical applications.

The IRIS-GR3 integrates co-aligned visible green and infrared aiming lasers, enabling precise daylight zeroing with the green laser and seamless transition to IR operation under night-vision devices. The inclusion of a powerful 60 mW VCSEL IR illuminator provides excellent reach and clarity in low-light and no-light environments. With a top-mounted beam control slider, users can rapidly adjust the IR illuminator from a wide flood to a focused spot, ideal for both close manoeuvres and longer-range observation.

Designed for speed and efficiency, the IRIS-GR3 features a central fire button for ambidextrous activation, dual rear selectors for intuitive mode and power changes, and a low-profile two-button Crane-plug remote with a visible laser override. Compact, rugged, and purpose-built, the IRIS-GR3 delivers dependable, mission-ready performance in any environment.
