Holosun IRIS-GR2 Laser - Green & IR - The Holosun IRIS-GR2 is a next-generation, dual-function aiming device engineered for professionals who demand versatility, precision, and a compact form factor.

The center-positioned fire button supports both momentary and constant ON modes, while a rear-facing power and mode selector switch enhances ergonomics and ease of use.
