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.

DESCRIPTION

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.

WHAT'S IN THE BOX
  • Holosun IRIS-RD-4 Red & IR Laser & IR Illuminator & Whitelight
FREQUENTLY ASKED QUESTION(S)

1. What functions does the IRIS-RD4 have?
It combines a visible red laser, IR laser, IR illuminator, and a white tactical light in one unit.

2. What is the white light output?
It produces about 1,000 lumens with high candela output for target identification.

3. What is the IR illuminator used for?
It provides infrared light that’s only visible through night vision devices, helping you see and identify targets in the dark.

4. What’s the benefit of the IR laser?
It lets you aim using night vision goggles without visible light giving away your position.

5. What does “co-aligned lasers” mean?
It means the visible and IR lasers are aligned to the same point, so zeroing one effectively aligns both.

6. Can you adjust the IR beam shape?
Yes, the IR illuminator can be adjusted from a wide flood beam to a narrow spot for different distances.

7. What is it made from?
It uses 7075-T6 aluminum for a strong but lightweight housing.

8. How is it powered?
It runs on CR123A batteries or a rechargeable 18650 battery option depending on setup.

9. Is it suitable for night vision setups?
Yes, it’s designed specifically to support both IR laser aiming and IR illumination for NV use.

10. What’s the main advantage of the IRIS-RD4?
It replaces multiple separate devices (white light, IR laser, IR illuminator, and visible laser) with one compact, integrated system.
