The Holosun IRIS-GR4 is a compact, quad-function aiming and illumination system developed for professional, law-enforcement and enthusiast users who require absolute versatility in both day and night operations. Precision-machined from durable 7075-T6 aluminium, the updated housing is 43% lighter, 29% lower and 28% narrower than the legacy LS420, offering improved ergonomics and streamlined weapon integration on PDWs, SBRs and full-length rifles.
Combining a co-aligned visible green laser, IR aiming laser, 60 mW VCSEL IR illuminator and a powerful 1,000-lumen white light, the IRIS-GR4 provides seamless capability across daylight aiming, night-vision engagements and high-intensity illumination. Co-alignment ensures fast, simple zeroing, users can adjust both IR and visible lasers simultaneously using the daylight-visible green laser.
A top-mounted IR beam divergence slider provides rapid control over the IR illuminator’s output, allowing instant transitions from wide flood to tight spot. Dual independent fire buttons deliver intuitive, ambidextrous activation of laser and white light functions, while the rear power/mode selector ensures effortless operation under pressure. The included Crane-plug three-button remote offers further flexibility, including a visible laser override for immediate activation.
Powered by either two CR123A batteries (included) or one 18650 rechargeable cell (not included), the IRIS-GR4 delivers reliable, adaptable performance in all conditions.
