Description
Transform your rifle into a complete day-and-night targeting system with four mission-critical functions integrated into one compact, lightweight package.
The Holosun IRIS-GR4 eliminates the need to mount multiple devices on your rifle rail by combining a visible green laser, infrared laser, IR illuminator, and high-output white light into a single unit that’s 43% lighter than previous generations. Whether you’re transitioning from daylight operations to night vision engagements or need immediate white light for positive identification, the IRIS-GR4 provides professional-grade capability at a fraction of the cost of military-contract laser systems. The co-aligned laser design means you can zero both visible and IR lasers simultaneously in daylight conditions, streamlining setup and ensuring consistent point-of-aim across all lighting environments.
Key Features
- Quad-Function Integration: Combines visible green laser (Class 3R, <5mW), IR laser (<0.7mW), 60mW VCSEL IR illuminator with adjustable beam divergence, and 1,000-lumen white light (25,000 candela) in one unit
- Redesigned Compact Housing: Precision-machined 7075-T6 aluminum construction that’s 43% lighter, 29% lower, and 28% narrower than the legacy LS420 series, freeing up valuable rail space
- VCSEL Technology: Vertical-cavity surface-emitting laser provides uniform, power-efficient IR illumination with clean beam quality for enhanced depth perception under night vision
- Dual Independent Controls: Ambidextrous fire buttons for tactile activation of lasers and light, plus rear-positioned power and mode selector for streamlined operation with or without gloves
Important Compatibility Notes
- Mounts to any standard Picatinny/MIL-STD-1913 rail
- Optimized for use with PDWs, SBRs, and standard rifle platforms
- IR functions require night vision devices to observe
Why We Carry It
The IRIS-GR4 represents a significant shift in the civilian laser market, delivering VCSEL-based illumination technology and multi-function capability previously locked behind military budgets. User feedback consistently highlights the unit’s exceptional value proposition—offering performance comparable to devices costing three to four times as much. The IRIS series has earned recognition from night vision professionals and civilian shooters alike for maintaining zero retention through extended firing sessions, producing clean IR outputs without excessive bloom, and providing intuitive controls that work under stress. We stock this system because it democratizes access to professional-grade night vision capability while eliminating the need for multiple rail-mounted devices.
Frequently Asked Questions
How do I zero the visible and IR lasers?
The visible green laser and IR laser are co-aligned, meaning you can zero both simultaneously using only the visible laser in daylight conditions. Adjust windage and elevation using the recessed adjustment screws (0.5 MOA per click) while observing your visible laser impact. Once zeroed, your IR laser will maintain the same point-of-aim. Total adjustment range is ±50 MOA. This eliminates the need for night vision equipment during the initial zeroing process.
What’s the difference between the IR illuminator’s flood and spot modes?
The top-mounted beam divergence slider allows you to adjust the IR illuminator pattern from wide flood (for close-quarters illumination and enhanced depth perception) to tight spot (for identifying targets at greater distances). This adjustment is made with a simple slider control and doesn’t require tools, allowing you to optimize the beam pattern based on your engagement distance and environment while using night vision devices.
How does battery life compare between CR123A and 18650 batteries?
The unit operates on either two CR123A batteries or one 18650 rechargeable battery. While Holosun lists multiple mode options, the specific runtime varies by the function selected. The 18650 option provides extended runtime and rechargeable convenience for frequent users, while CR123A batteries offer the advantage of long shelf life and easy field replacement. Many users keep both battery types available for operational flexibility.
