Holosun – IRIS-RD4 Quad Laser & White Light System

The Holosun IRIS-RD4 is a compact, quad-function aiming and illumination system designed for modern night-fighting, duty, and defensive rifle platforms. Precision-machined from 7075-T6 aluminum, the redesigned housing is significantly lighter, lower, and narrower than legacy units—making it an ideal solution for PDWs, SBRs, and full-size rifles where performance and ergonomics matter.

The IRIS-RD4 integrates a co-aligned visible laser, infrared (IR) aiming laser, VCSEL-based IR illuminator, and a powerful white light into a single streamlined unit. This allows seamless transitions between daylight aiming, night vision operations, and high-intensity white light use without changing equipment or mounting solutions.

• Quad-function system: visible laser, IR laser, IR illuminator, and white light
• Co-aligned visible and IR lasers for simplified zeroing
• Optimized for PDWs, SBRs, and rifle platforms
• Precision 7075-T6 aluminum housing with hard anodized finish

At the core of the IRIS-RD4 is a powerful illumination package. The white light delivers 1,000 lumens and 25,000 candela for target identification and situational awareness, while the 60mW VCSEL-based IR illuminator provides strong performance under night vision. A top-mounted IR beam divergence slider allows instant adjustment from wide flood to tight spot, adapting to close-quarters or extended-range use on the fly.

• 1,000-lumen white light with 25,000 candela
• 60mW VCSEL IR illuminator
• On-the-fly IR beam divergence adjustment
• Effective performance through photonic barriers

Control ergonomics are purpose-driven and intuitive. Dual independent fire buttons provide ambidextrous activation of laser and illumination functions, while the rear-mounted power and mode selector streamlines operation. The included three-button remote pressure pad connects via a Crane plug and features a visible-laser override for immediate activation when needed.

• Ambidextrous dual fire buttons
• Rear-positioned power and mode selector
• Crane-plug compatible triple-button pressure pad included
• Visible laser override on remote switch

The IRIS-RD4 offers flexible power options to suit different operational needs. It can run on two included CR123A batteries or a single rechargeable 18650 battery (not included), ensuring reliable performance across environments and mission profiles.

• Powered by 2× CR123A batteries (included)
• Compatible with single 18650 rechargeable battery (not included)
• Designed for consistent output and reliability
