Holosun IRIS 4 | Visible/IR Laser, IR Illuminator & Light | Granite Ridge Defense

IRIS 4 is a four-function multi-laser device housed in a redesigned 7075 aluminum shell that is 43% lighter, 29% shorter, and 28% narrower than the previous model. IRIS 4 now features a powerful 60mW infrared (IR) illuminator and a 1,000 lumen / 25,000 candela white light, along with a VIS (visible) laser pointer and an infrared (IR) laser pointer. Additionally, it has independent fire buttons for ambidextrous activation of the lasers and white light in both momentary and constant ON modes. IRIS 4 also includes an improved rear-facing power and mode selector switch for better ergonomics and feel. A new three-button remote activation switch is included, which features a VIS override function.

Granite Ridge's Take

The Holosun IRIS 4 expands the IRIS platform into a quad-function module by combining a visible laser, infrared aiming laser, VCSEL infrared illuminator and integrated white light in one compact 7075-T6 aluminum housing. It is designed for shooters who want one rail-mounted unit to handle both visible-light and night-vision-oriented functions.

Buying & Compatibility Notes

The IRIS 4 mounts directly to Picatinny rail and supports either a rechargeable 18650 battery or two CR123A batteries. Holosun's current product page lists a 1,000-lumen white light with 25,000 candela, plus IR aiming and illumination functions and red or green visible-laser variants.
