Introduction
The Holosun IRIS-RD4 is a quad-function multi-laser device designed for versatile applications. It features a robust 7075 aluminum housing, offering a compact and lightweight design. This device integrates a powerful infrared (IR) illuminator, a high-lumen white light, a visible (VIS) laser pointer, and an infrared (IR) laser pointer.
Key features include independent fire buttons for ambidextrous activation of momentary or constant ON functions for both lasers and the white light. An updated, rear-facing power and mode selector switch enhances ergonomic control. The IRIS-RD4 also comes with a three-button remote activation switch, which includes a VIS override function.

Operating Instructions
The IRIS-RD4 offers multiple functions controlled by its integrated switches and remote activation switch.
- Power/Mode Selector Switch: Located at the rear of the unit, this switch controls the overall power and selects the operating mode (e.g., IR laser, VIS laser, IR illuminator, white light). Rotate or slide the switch to cycle through available modes.
- Independent Fire Buttons: The device features separate buttons for activating the laser functions and the white light. Press and hold for momentary activation, or press and release for constant ON, depending on the selected mode and configuration.
- IR Illuminator: The 60mW IR illuminator provides infrared light for use with night vision devices. It features quick adjustable focus to tailor the beam spread.
- White Light: The 1,000 lumen / 25,000 candela white light provides powerful visible illumination.
- VIS Laser Pointer: The visible red laser pointer (5mW) is used for aiming and target designation.
- IR Laser Pointer: The infrared laser pointer (0.7mW VCSEL) is used for aiming with night vision devices.
- Remote Activation Switch: The included three-button remote switch allows for convenient activation of functions without breaking your grip. It also includes a VIS override function for quick access to the visible laser.
- High/Low Intensity Selector Switch: Adjust the output intensity of certain functions using this dedicated switch.
- Coaxial Laser Mechanism: This design ensures that the visible and infrared lasers are aligned for consistent aiming.
Refer to the markings on the device for specific button functions and switch positions.
