Description
This compact dual-laser aiming system brings professional-grade targeting to your rifle with co-aligned green and IR lasers in a lightweight, combat-ready package.
Co-zeroing your visible and infrared lasers shouldn’t require multiple range trips or complex adjustments. The IRIS-GR2’s co-aligned laser system lets you zero both lasers simultaneously using the visible green laser in daylight, then seamlessly transition to IR operations with night vision equipment. At just 5 ounces and sitting substantially lower than previous-generation models, this laser module saves crucial rail space while delivering the precision targeting capabilities demanded by professionals and serious enthusiasts alike.
Key Features
- Co-Aligned Laser System: Green visible laser and IR laser are factory co-aligned, allowing simultaneous zeroing in daylight conditions for consistent point-of-aim across all lighting environments
- Compact 7075-T6 Housing: Precision-machined aluminum construction delivers exceptional durability at only 5 ounces while sitting 21% lower on your rail than predecessor models
- Dual Activation Options: Center-mounted ambidextrous fire button plus included Crane-plug compatible remote switch provide flexible activation for any shooting position or setup
- Precise Adjustments: Recessed windage and elevation controls with 0.5 MOA clicks and ±50 MOA total travel range ensure accurate zeroing and prevent inadvertent changes during use
Why We Carry It
The IRIS-GR2 represents Holosun’s response to feedback from shooters who needed full laser capabilities without the bulk of triple-function units. By focusing exclusively on dual-laser functionality, Holosun engineered a module that’s 45% lighter and 21% lower than their previous LS221 series while maintaining the same rugged construction and precision adjustments. This makes it ideal for builds where every ounce matters or where you’re already running a dedicated IR illuminator and simply need reliable visible and IR aiming capabilities.
Important Compatibility Notes
- Requires Picatinny/MIL-STD-1913 rail for mounting
- Remote switch uses Crane-style plug (compatible with industry-standard Crane-spec remote ports)
- Designed for rifles; not recommended for handgun applications
- IR laser requires night vision equipment to observe beam
Can I zero the visible and IR lasers at the same time?
Yes. The IRIS-GR2 features co-aligned lasers, meaning when you zero the visible green laser using your daylight optic, the IR laser is simultaneously zeroed to the same point of impact. This eliminates the need for separate night vision zeroing sessions.
What’s the difference between the IRIS-GR2 and IRIS-GR3?
The IRIS-GR2 is a dual-laser unit (visible green + IR laser only), while the IRIS-GR3 adds a 60mW IR illuminator as a third function. If you already run a weapon-mounted IR light or don’t need built-in illumination, the GR2 offers a more compact and affordable option. If you need illumination integrated into your laser unit, consider the GR3.
How do I switch between the visible laser and IR laser?
The rear-facing mode selector switch lets you choose between visible-only, IR-only, or dual-laser modes. Power settings (low/high) are also controlled via the rear switch. The fire button or remote switch then activates whichever mode you’ve selected.
Care Instructions
The IRIS-GR2’s sealed construction and durable anodized finish require minimal maintenance. Periodically inspect the laser apertures and wipe clean with a microfiber cloth if debris accumulates. Check mounting screws for tightness after initial installation and after exposure to heavy recoil. Store with the battery removed if the unit will not be used for extended periods. The IPX8 waterproof rating means the unit can withstand temporary submersion, but ensure the battery compartment is properly sealed before exposure to wet conditions. Avoid pointing lasers at reflective surfaces during testing, and always follow laser safety protocols.
