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. The IRIS-3 features an IPX8 waterproof housing with a centrally located fire button, rear-facing power and mode switches, and a small two-button remote switch with momentary and constant-on functionality.
Adjust the laser beam for windage and elevation at 1/2 MOA per click, with a total adjustment range of 100 MOA. Whether for precision shooting, tactical operations, or night vision applications, the IRIS-GR3 combines versatility and reliability in a rugged, compact design.
