Product Description

The Holosun IRIS-GR3-FDE (SKU: IRIS-GR3-FDE / UPC: 810047074823) sets a groundbreaking standard for compact, tactical night-vision aiming modules. Engineered as an integrated triple-function weapon system, the IRIS (Integrated Rifle Infrared System) combines an ultra-bright 520nm Class 3R visible green laser, an eye-safe Class 1 820–880nm infrared aiming laser, and a cutting-edge 60mW Vertical-Cavity Surface-Emitting Laser (VCSEL) infrared illuminator into a single ultra-low-profile chassis. Designed for aggressive close-quarters target acquisition, defensive carbines, and long-range passive/active night-vision engagements under helmet-mounted NODs, the IRIS delivers full-spectrum operational capability while significantly reducing weapon front-end weight and muzzle bias.

Forged and precision CNC-machined from solid billet 7075-T6 aerospace aluminum, the housing provides exceptional structural integrity against severe recoil, barrel heat, and violent muzzle blasts from short-barreled rifles and suppressed carbines. Finished in an abrasion- and solvent-resistant Flat Dark Earth (FDE) Type III hardcoat anodize, the IRIS-GR3-FDE carries an IPX8 immersion rating and withstands up to 1,000G of mechanical shock. Internally, Holosun incorporates an advanced VCSEL diode architecture that generates a pristine, circular, speckle-free infrared illumination beam free from the dirty optical artifacts common to legacy edge-emitting laser diodes. A top-mounted ergonomic beam divergence lever allows operators to smoothly throttle the IR illuminator from a wide situational flood down to a concentrated long-range pinpoint spotlight instantly on the fly.

Ergonomically refined for modern forward-grip hand placements, the IRIS-GR3-FDE sits 20% lower than legacy aiming units and weighs an agile 6.4 ounces, ensuring co-witnessed optical line-of-sight clearance through standard lower-third red dot risers and 1.93" NV mounts. The chassis features a centralized, ambidextrous rubberized fire button paired with intuitive rear-facing rotary selectors for seamless low/high mode selection without breaking the shooting grip. Ships complete with an ultra-compact two-button remote tape switch featuring an integrated visible override (VIS Override) toggle, an integral MIL-STD-1913 Picatinny mount, and a high-capacity CR123A battery compartment designed for rapid battery swaps without unmounting the module or disrupting your confirmed zero.

*Armorer Bench Notes & Real-World Staging Guidance:*

Fitment Matrix: Direct clamp installation onto any true MIL-STD-1913 Picatinny top rail or monolithic receiver. CRITICAL: Do not install onto undersized commercial polymer rails or non-mil-spec Weaver slots. Due to the coaxial design, zeroing the visible green laser automatically slaves and zeros the IR aiming laser simultaneously. Always use an inch-pound torque wrench to torque the mount cross-bolt clamp to exactly 20 to 25 in-lbs onto a clean, degreased rail slot; over-torquing can damage the internal rail clamp, while under-torquing risks point-of-impact shift under heavy 5.56 NATO or .308 Win recoil pulses. Use medium-strength threadlocker (Vibra-TITE 121 or Blue Loctite 242) on mounting fasteners if running dedicated hard-use carbines.

1. Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty. Lock the bolt to the rear and place the safety selector on SAFE before mounting.
2. Clean and degrease the host 12 o'clock Picatinny rail section forward of your primary optic or backup iron sights; ensure clear line-of-sight clearance for both optical diodes and front hand placement.
3. Loosen the integrated rail cross-bolt, seat the IRIS-GR3-FDE squarely into the desired Picatinny recoil groove, and push the chassis firmly forward toward the muzzle to seat the cross-bolt against the forward rail lug face.
4. Using a calibrated in-lb torque driver, torque the clamp bolt to 20–25 in-lbs. Route the included dual-button remote pressure switch cable along the handguard, securing excess slack to avoid snag hazards or hot barrel contact.
5. Perform a live function test through all rotary mode settings (Off, Low VIS, High VIS, Low IR, High IR, Dual IR). Zero the visible green aiming point at 50 or 100 yards using the 0.5 MOA turrets during daylight, and confirm parallel slaved IR pointer and illuminator convergence under night vision goggles during low-light staging readiness.

Key Features

• Triple-Laser Mission Capability: Houses a high-visibility Class 3R 520nm green daylight pointer, a Class 1 eye-safe IR aiming laser, and a variable-focus 60mW VCSEL IR illuminator in a single chassis.
• VCSEL Illuminator Technology: Next-generation Vertical-Cavity Surface-Emitting Laser delivers clean, smooth, halo-free beam illumination without diode speckle or dead spots.
• Coaxial Laser Slaving: Windage and elevation turrets adjust both visible green and infrared aiming beams concurrently, allowing rapid daylight zeroing without dedicated NVG range sessions.
• 7075-T6 Aerospace Aluminum Housing: Ruggedized, CNC-machined metal housing engineered for harsh tactical deployments, offering IPX8 waterproof integrity and 1,000G shock resistance.
• Ultra-Low Profile Footprint: Sits 20% lower than previous generation laser modules, clearing line of sight for 1.54", 1.93", and 2.26" optic mounts while weighing only 6.4 oz.
• Tactile Top-Mounted Focus Slider: Rapidly transitions the 60mW IR illuminator from wide flood room-clearing beam divergence to a tight, high-candela distance spotlight.
• Included Dual-Button Remote Switch: Features dedicated momentary and constant-on buttons along with a high-priority Visible Override button for instant white-light/daylight transition drills.
• Standard CR123A Battery Powered: High-efficiency circuit architecture powered by a ubiquitous single CR123A 3V lithium cell with front-facing battery cap accessibility.
