The Holosun IRIS-GR2 Green is a compact dual-laser aiming module built for modern rifle setups where you want both daylight and night-vision capability in one unit. It gives you a visible green laser for fast daytime aiming and an IR laser for use with night vision, with both lasers co-aligned so they share the same point of impact for easier zeroing. It’s built from lightweight 7075-T6 aluminum and designed to sit lower and slimmer than older Holosun laser units, so it doesn’t eat up rail space or feel bulky. You also get simple, glove-friendly controls with multiple activation modes and a rugged, sealed body built for recoil, water, and field use. In short, it’s a stripped-down, efficient “green + IR only” laser system for users who don’t need illumination but still want serious NV capability.

DESCRIPTION

The Holosun IRIS-GR2 is a next-generation dual-function aiming module engineered for users who require absolute precision, operational versatility, and a lightweight footprint. Constructed from upgraded 7075-T6 aluminium, the IRIS-GR2 delivers a 45% weight reduction and a 21% lower profile compared to the previous LS221 series, making it an ideal companion for modern rifle setups where space and weight truly matter.

This advanced module integrates co-aligned visible green and IR lasers, enabling efficient daylight zeroing of both systems using the visible laser alone. A centre-positioned fire button provides both momentary and constant-on activation, complemented by a rear-facing power/mode switch for improved ergonomics under stress. For additional flexibility, Holosun includes an ultra-compact single-button remote switch with a Crane-style plug for seamless integration with popular setups.

Compact, rugged, and mission-ready, the IRIS-GR2 is fully waterproof, shock-resistant, and built to keep performing in the harshest conditions imaginable.

  • Optimised Low Profile – Redesigned to sit lower on the rail, improving compatibility with modern optics and reducing snag risk.
  • Intuitive Controls – Central activation button and rear selector switch provide fast, positive control even with gloves or under pressure.
  • Remote Activation Ready – Comes with a compact remote switch for off-hand activation without shifting grip or stance.
  • Mission-Ready Durability – Waterproof to IPX8 standards, resistant to shock and recoil, and built to withstand harsh climates and field conditions.
  • Modern Rifle Integration – Compact footprint ensures compatibility with rails, clip-on devices, and low-mount accessories.
