Holosun LS321R Multi Laser Device Red Laser IR Laser and IR Illuminator

DescriptionThe Holosun LS321R combines a visible red laser, an IR laser, and an IR illuminator in one coaxially aligned unit for efficient targeting with or without night vision.Whether you’re engaging targets in daylight or running night vision equipment, the Holosun LS321R eliminates the need for multiple aiming devices. This multi-function laser allows you to transition seamlessly between visible red targeting and IR operation with a simple mode selector switch, while the coaxial design means zeroing one beam zeros them all. Built from military-grade 7075 aluminum with IP67 waterproofing, this device delivers reliable performance across varying conditions while maintaining a compact footprint on your rail.Key FeaturesThree-in-One Coaxial System: Integrates class IIIA visible red laser (1-5mW), class 2M IR laser (0.1-0.7mW), and IR illuminator (0.7mW) in perfect alignment for simplified zeroing and faster target acquisitionExtended Battery Life: Single CR123A battery provides up to 5,000 hours of operation, reducing the need for frequent battery changes during extended operations or trainingMilitary-Grade Construction: CNC-machined from 7075-T6 aluminum with MAO (Micro-Arc Oxidation) surface finish, weighing just 8.64 oz while maintaining exceptional durability and corrosion resistanceVersatile Mounting System: Quick-release Picatinny mount with tactile windage and elevation adjustments (0.5 MOA per click, ±50 MOA travel range) plus included remote pressure switch for convenient activationImportant Compatibility NotesTop-Mount Adjustment: When mounted at 12 o’clock position, windage and elevation adjustments operate in reverse (what’s marked for windage adjusts elevation and vice versa). The unit is typically designed for 3 o’clock side mounting.Night Vision Requirement: IR laser and illuminator functions require night vision devices to be visible. This is a civilian-powered unit designed for eye-safe operation.Rail Space: Requires approximately 3.6 inches of continuous Picatinny rail space for mounting.Why We Carry ItThe Holosun LS321R laser represents Holosun’s commitment to bringing multi-function aiming capability to civilian shooters at an accessible price point. Since its introduction, this device has become a popular choice for those entering the night vision shooting market, offering coaxially aligned lasers that simplify the zeroing process. User reviews consistently highlight its value proposition—delivering reliable, visible, and IR targeting capabilities without the premium pricing of military-contract-grade units.Frequently Asked QuestionsCan I use this device without night vision equipment?Yes, the visible red laser functions independently and can be used for standard daytime or low-light targeting without night vision. However, the IR laser and IR illuminator are only visible through night vision devices. The mode selector allows you to choose between visible-only modes or IR-only modes depending on your setup.How do I zero all three beams on this device?The coaxial design means all three beams are perfectly aligned, so adjusting the windage and elevation dials zeros all beams simultaneously. Start by zeroing the visible red laser at your preferred distance (typically 25 yards), and your IR laser will be automatically zeroed as well. Note that if you mount the unit at the 12 o’clock position, the adjustment directions will be reversed from what’s marked.What’s the effective range of the IR illuminator?The LS321R uses a civilian-legal, eye-safe IR illuminator rated at 0.7mW. Effective illumination range depends on ambient light conditions and your night vision device quality, but users typically report useful illumination out to approximately 50-100 yards in complete darkness. The rear-mounted focus adjustment knob allows you to adjust the beam spread for your specific needs—tighter for distance or wider for close quarters.Spec SheetElectronic DataPower Source: BatteryBattery Type: CR123ABattery Life: Up to 5,000 hoursBrightness Settings: High/Low modesPhysical DataDimensions: 3.6″ × 2.2″ × 1.6″Weight: 8.64 ozWindow Size: N/AMechanical DataHousing Material: 7075-T6 AluminumSurface Finish: MAO (Micro-Arc Oxidation)Adjustment per Click: 0.5 MOAWindage & Elevation Travel Range: ±50 MOAEnvironmental DataStorage Temperature: -40°C to 65°C (-40°F to 149°F)Working Temperature: -40°C to 51°C (-40°F to 123°F)Water Resistance: IP67 (dustproof, waterproof to 1m for 30 minutes)Vibration Resistance: 1000GLaser DataLaser & Illuminator Type: Dual Laser & IR IlluminatorVisible Laser Class: IIIAVisible Laser Output: 1mW (low) / 5mW (high)IR Pointer Class: 2MIR Pointer Output: 0.1mW (low) / 0.7mW (high)IR Illuminator Output: 0.7mWWhite LED Output: N/A
