Holosun IRIS-GR4

The Holosun IRIS-GR4 represents an evolution in multi-function weapon accessories, combining four essential capabilities in a single integrated package: a 1,000-lumen white LED weapon light (25,000 candela), 60mW VCSEL IR illuminator, co-aligned visible laser (5mW green or red), and 0.7mW IR laser. This quad-function design eliminates the need for separate weapon light and laser units, reducing weight, rail space, and complexity while maintaining professional-grade performance across all functions.

Built from 7075-T6 aluminum with hard anodize finish, the IRIS-GR4 achieves a 43% weight reduction, 29% lower profile, and 28% narrower footprint compared to Holosun's legacy LS420 series. The white light output of 1,000 lumens at 25,000 candela provides effective target identification out to 316 meters, while the 60mW VCSEL IR illuminator delivers the same clean, speckle-free infrared lighting found in the IRIS-GR3. The top-mounted beam divergence slider allows rapid adjustment from tight spot to wide flood for both white and IR illumination.

The co-aligned visible and IR lasers simplify zeroing procedures—dial in the visible laser during daylight and the IR laser is automatically aligned for night vision operations. Dual independent fire buttons provide ambidextrous activation, and the included three-button remote with Crane plug offers flexible switch placement. With 0.5 MOA per click adjustments and ±50 MOA total travel, the IRIS-GR4 enables precise zeroing across various platforms. IPX8 waterproof rating and 1000G vibration resistance ensure reliable operation in adverse conditions.
