Holosun IRIS-RD2 Laser - Red & IR - The Holosun IRIS-RD2 is a next-generation, dual-function aiming device engineered for professionals who demand versatility, precision, and a compact form factor. Designed with an upgraded 7075-T6 aluminum housing, the IRIS-RD2 delivers a 45% weight reduction and 21% lower profile compared to the previous LS221 series, making it an excellent fit for modern rifle builds.

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. An ultra-compact single-button remote switch with a Crane-style plug is also included for additional activation flexibility.
