Holosun IRIS-4 Laser, Illuminator & White Light

The Holosun IRIS-GR4 is a compact quad-function aiming system engineered for modern professionals and enthusiasts. Precision-machined from 7075-T6 aluminum, the redesigned housing is 43% lighter and significantly more compact than the legacy LS420, delivering superior ergonomics ideal for PDWs, SBRs, and standard rifle platforms.

The system combines a co-aligned visible green laser, IR aiming laser, 60mW VCSEL-based IR illuminator, and 1,000-lumen white light with 25,000 candela output. Co-aligned lasers simplify zeroing—calibrate both IR and visible lasers simultaneously in daylight for consistent point-of-aim across all environments.

An adjustable top-mounted IR beam divergence slider transitions from wide flood to tight spot for varied shooting needs. Dual independent fire buttons provide tactile, ambidextrous control of laser and light functions, while the rear-positioned power and mode selector streamlines operation.

Includes a three-button remote with visible laser override for instant activation. Powers via two CR123A batteries (included) or one rechargeable 18650 battery (not included) for reliable performance in any environment.
