Holosun IRIS-RD4 IRIS 4 Red/IR Laser & 1000 Lumen Light

The Holosun IRIS-RD4 IRIS 4 is a compact, quad-function aiming and illumination system integrating a visible red laser, an infrared aiming laser, a VCSEL-based IR illuminator, and a high-output white light. Precision-machined from 7075-T6 aluminum, the redesigned housing is significantly reduced in size and weight from the legacy LS420 platform for improved ergonomics on PDWs, SBRs, and standard rifle platforms. Ambidextrous controls, a three-button remote with a visible-laser override, and support for a USB-C rechargeable 18650 or dual CR123A batteries provide flexible operation across lighting conditions.
