The Holosun IRIS-GR3 is a professional-grade, triple-function laser and illumination device engineered to deliver maximum capability in an ultra-compact footprint. Constructed from redesigned 7075-T6 aluminum, the IRIS-GR3 is 43% lighter and 20% lower in profile than the LS321 series, providing enhanced ergonomics while maintaining exceptional durability and operational reliability.

This advanced system integrates co-aligned visible green and infrared (IR) aiming lasers, allowing precise zeroing during daylight using the visible laser, with seamless transition to IR functionality for night operations. A high-output 60mW VCSEL IR illuminator delivers outstanding performance in low-light and no-light environments when used in conjunction with night vision devices. A top-mounted beam adjustment slider enables fast, glove-friendly tuning of the IR illuminator’s beam from wide to narrow for optimal performance across varying distances.

Additional features include a centrally positioned fire button for ambidextrous activation, dual rear-facing selectors for intuitive power and mode control, and a low-profile two-button remote switch with Crane plug and VIS override. The IRIS-GR3 offers dependable performance and advanced functionality in a rugged, precision-built compact platform.
