The IRIS RD4 multifunctional laser by Holosun combines a laser sight and flashlight into a single compact unit, making it highly suitable for modern long firearms. The visible laser, infrared laser, infrared illuminator and powerful white light are all integrated into one body. The entire setup is designed to simplify the transition between daytime laser use, night vision and working with white light. The controls are straightforward, logical and avoid unnecessary steps. Once zeroed in, the laser aim remains consistent regardless of the mode. It is exactly the type of accessory that saves space on the rail.
The IRIS RD4 combines a visible red laser, infrared laser, infrared illuminator and white light. This eliminates the need to handle several separate devices. Transitioning between modes happens smoothly according to current needs. The system handles work in daylight, works with night vision and deploys white light without changing the setup or grip of the weapon.
The visible and infrared lasers are synchronized. Adjustment is done via the visible laser in daylight and the same point of aim is used for the infrared mode. This eliminates the need for lengthy adjustments at night or with night vision. The aiming point remains consistent across modes, providing assurance when light conditions change.
The top controller allows instant adjustment of the infrared illuminator's character. A wide spread covers nearby areas, while a narrower beam is suitable for longer distances. Adjustments are made directly on the device without tools and without removing it from the weapon. The lighting, therefore, adapts to the situation. A practical solution for variable conditions.
Separate buttons for the laser and light provide clear feedback when pressed. The controls are ambidextrous and easily accessible from various grips. The mode switch is placed so it doesn't get in the way but is immediately at hand. It includes a remote control with direct access to the visible laser.
The body is crafted with precision machining of an aluminum alloy used in aviation. Compared to older solutions, it is more compact, lower and narrower, without compromising strength. The dimensions facilitate mounting on PDWs, short carbines and standard rifles. The unit feels balanced and doesn't overload the front of the weapon. The construction is built to withstand harsh handling and recoil.
The IRIS RD4 allows a choice between conventional batteries and a rechargeable battery. This allows the power supply to be adapted to availability and preferences. The device is ready to operate in different conditions without complex logistics. The performance remains stable regardless of the chosen power type. A practical assurance for the field and the shooting range.
