Holosun IRIS-RD-44 Function Red & IR Laser & IR Illuminator & Whitelight
The Holosun IRIS-RD4 is basically a full “do everything” laser and light unit packed into one compact body. It gives you a visible red laser, IR laser for night vision use, a powerful IR illuminator, and a 1,000-lumen white light all in one setup, so you’re covered whether it’s daytime shooting, low light, or NVG work. It’s built from lightweight 7075 aluminum and designed to sit tighter and lower on a rail than older units, so it doesn’t feel as bulky as you’d expect for something this capable. You also get co-aligned lasers for easier zeroing and consistent point of aim across modes, plus adjustable IR beam spread so you can go from flood to spot depending on distance. It’s very much a “one box replaces multiple devices” setup for serious rifle use.

The Holosun IRIS-RD4 is a compact, high-performance quad-function aiming and illumination system designed for professionals and demanding shooters who require adaptability across both daylight and night-vision environments. Precision-machined from rugged 7075-T6 aluminium, the redesigned chassis is 43% lighter, 29% lower and 28% narrower than the legacy LS420. The result is a slimmer, lighter, and more ergonomic unit suited perfectly to PDWs, SBRs and full-length rifles.
At the core of the IRIS-RD4 is the integration of a co-aligned visible red laser, IR aiming laser, a powerful 60 mW VCSEL IR illuminator, and a 1,000-lumen white light generating 25,000 candela. This provides seamless transitions between daylight red-laser aiming, night-vision IR engagements, and high-intensity white-light illumination. With both lasers co-aligned, users can zero the visible laser in daylight and automatically align the IR laser to the same point-of-aim for instant consistency across all lighting conditions.
A top-mounted IR beam divergence slider allows rapid shaping of the IR illuminator from wide flood to narrow spot, optimising visibility for close-in search or long-range use. Dual independent fire buttons offer tactile, ambidextrous control of laser and white-light functions, supported by a refined rear power and mode selector. The included Crane-plug three-button remote provides even greater flexibility, including a visible-laser override.
Compatible with either two CR123A batteries (included) or a single rechargeable 18650 cell (not included), the IRIS-RD4 ensures reliable, high-output operation in all environments.
