Holosun SCS-320-GR — Solar Charging Pistol Sight with Green MRS ReticleThe Holosun SCS-320-GR (Solar Charging Sight) is a dedicated enclosed reflex sight designed for direct mounting on the SIG Sauer P320 OR (Optics Ready) and DPP-footprint platforms without adapter plates. It combines a green MRS reticle (2 MOA dot + 32 MOA circle) with a built-in rechargeable lithium-ion battery and Solar Failsafe panel, delivering effectively unlimited operating time under any ambient light source. At 38 g (1.35 oz) and a sight height of 26.9 mm, it is one of the lightest and lowest-profile enclosed pistol sights on the market, allowing standard-height iron sights to be used as emergency backup.Housing and ConstructionMachined from 7075-T6 aluminum with a matte black anodized finish. Weight is 38 g (1.35 oz) with dimensions of 47 × 29 × 27 mm. Rated IP67 (submersion to 1 m for 30 minutes) and validated to 5,000 G vibration resistance — significantly higher than the typical 1,000 G spec of rifle optics, reflecting the harsher recoil environment of direct pistol mounting. Working temperature range is −30°C to +60°C, storage −40°C to +70°C.Optics and MRS ReticleMulti-layer anti-reflective coated lenses with a 23×16 mm (0.90″×0.63″) window. Magnification 1×, unlimited eye relief, zero parallax. The sight functions with both eyes open.Multi-Reticle System (MRS) — three selectable modes:2 MOA dot — precise aiming at medium distances32 MOA Circle — rapid target acquisition at close range. The 32 MOA diameter uniquely matches the size of a standard falling steel plate at 15 m in the BDS shotgun discipline — unlike the more common 65 MOA circles used by most competitorsCircle-Dot — 2 MOA dot inside 32 MOA circle for universal useReticle color: green, 540 nm wavelength.Power System: Solar Failsafe + Built-in Rechargeable BatteryThe SCS-320-GR uses a fundamentally different power architecture from conventional pistol optics. Instead of a user-replaceable CR2032, it incorporates a built-in lithium-ion rechargeable battery that is continuously charged by the integrated solar panel — the battery never needs to be removed or replaced.Without light: up to 20,000 hours of autonomous operationUnder any light source (daylight, office fluorescent, indoor range lighting): effectively unlimited operating timeLow battery indicator triggers days before the battery reaches critical levelSolar Failsafe: automatically reduces LED intensity when entering shade to conserve charge; continues displaying the reticle in any ambient light regardless of battery stateOverride Mode: single button press forces brightness to levels 9–12 (depending on conditions) for 30 minutes — for use in strong daylight or when stronger visibility is temporarily neededTechnical SpecificationsParameterValueSight TypeEnclosed Reflex SightMountDirect — SIG Sauer P320 OR / DPP footprintMagnification1×Window Size23×16 mm (0.90″×0.63″)Reticle2 MOA dot / 32 MOA circle / comboReticle ColorGreen (540 nm)Brightness ControlAuto + Override Mode (30 min)ParallaxParallax-freeEye ReliefUnlimitedMulti-Coated LensYesAdjustment per Click1.5 MOAW&E Travel Range±30 MOAPower SourceBuilt-in Li-Ion battery + solar panelBattery Life (no light)Up to 20,000 hoursBattery Life (with light)UnlimitedSolar FailsafeYesShake AwakeNoLast Setting MemoryNoHousing Material7075-T6 AluminumSurface FinishMatte Black AnodizedWeight1.35 oz (38 g)Dimensions47×29×27 mmSight Line Height26.9 mmWaterproofingIP67Vibration Resistance5,000 GWorking Temperature−30°C to +60°CStorage Temperature−40°C to +70°CNV CompatibleYesMounting and ZeroingThe sight mounts directly to the SIG Sauer P320 OR slide with two T10 Torx screws.

Holosun IRIS-GR3 — Triple-Function Green Laser and IR Illuminator ModuleThe Holosun IRIS-GR3 is a professional-grade, third-generation triple-function laser module integrating a Class 3R visible green laser (520 nm), a Class 1 IR aiming laser (850 nm), and a 60 mW VCSEL IR illuminator in a single Picatinny-ready housing. The IRIS-GR3 and IRIS-RD3 share identical form factors, dimensions, and weight — the difference lies in the visible laser: green (520 nm) versus red (635 nm). Green is roughly 4–6× more perceptible to the human eye at equivalent power, making the GR3 the preferred choice for positive target identification in daylight conditions and bright-sun environments.Compared to the predecessor LS321 series, the IRIS-GR3 housing is 43% lighter and 20% lower in profile, significantly improving weapon balance and rail real estate when running lights, foregrips, or other accessories simultaneously.Housing and ConstructionThe body is machined from 7075-T6 aluminum with a black hard-anodized finish, measuring 81 × 50 × 34 mm (3.2″ × 1.97″ × 1.34″) and weighing 181 g (6.4 oz). The unit is rated IPX8 for full water submersion. Vibration resistance is validated to 1000 G — sufficient for centerfire rifle calibers from 5.56 NATO to 7.62×39 mm. Mounting uses a single captive-screw Picatinny / Weaver clamp.Laser and Illuminator SystemVisible Green Laser (520 nm, Class 3R): low (1 mW, Class II) and high (5 mW, Class 3R) power levels. The 520 nm wavelength offers maximum daylight contrast for PID (positive identification) and field zeroing of the IR channel. Once zeroed on the visible green laser, the IR aiming laser is automatically aligned — no separate adjustment required.IR Aiming Laser (850 nm, Class 1): low (0.4 mW) and high (0.7 mW) power levels. Compatible with Gen 1, Gen 2, Gen 3, and digital NV monoculars and binoculars. Co-aligned with the visible laser.VCSEL IR Illuminator (850 nm, Class 1, 60 mW): VCSEL (Vertical Cavity Surface Emitting Laser) technology produces a perfectly circular, artifact-free beam — no rings or hot spots common with LED-based illuminators. A top-mounted beam-width slider continuously adjusts divergence from wide flood (15 mrad) to tight spot (up to 150 mrad), operable with gloves without changing grip. Two power levels: 10 mW (low) and 60 mW (high).Operating ModesThe rear rotary selector steps through four modes with two intensity levels each:Visible green laser onlyIR aiming laser onlyIR illuminator onlyIR laser + IR illuminator combinedTechnical Specifications Holosun IRIS-GR3ParameterValueVisible LaserClass 3R, 520 nm (Green), 1 mW / 5 mWIR Aiming LaserClass 1, 850 nm, 0.4 mW / 0.7 mWIR IlluminatorClass 1, VCSEL, 850 nm, 10 mW / 60 mWIR Beam Divergence15–150 mrad (adjustable)Laser Beam Divergence0.5 mradAdjustment per Click0.5 MOAW&E Travel Range±50 MOAPower SourceCR123AHousing Material7075-T6 Aluminum, Hard AnodizedWeight6.4 oz (181 g)Dimensions3.2″ × 1.97″ × 1.34″ (81 × 50 × 34 mm)WaterproofingIPX8Vibration Resistance1000 GWorking Temperature−30°C to +51°CStorage Temperature−40°C to +70°CMountPicatinny / Weaver (M1913)Controls and ErgonomicsThe center-positioned fire button on the top of the housing provides equal access for right- and left-handed operators without any grip change. Supports both momentary (press-to-activate) and constant-on (hold-to-lock) modes.The included dual-button remote switch with Crane plug mounts on the fore-end or vertical grip. The VIS override function forces the visible green laser from the remote regardless of the mode selector position — critical for instant target identification during NV operations without fumbling through mode changes.A red LED battery indicator warns of low charge before complete shutdown. Recessed 0.5 MOA/click adjustment turrets within ±50 MOA protect zero during transport and field handling.Field ApplicationsNight operations with NV devices. Co-aligned lasers eliminate dual-zeroing procedures. The 60 mW VCSEL illuminator delivers clean, even IR flood illumination for target identification in complete darkness at close to medium distances.Hunting at dusk and night. The adjustable illuminator switches from wide area flood (15 mrad) for general scene awareness to a focused spot (up to 150 mrad) for engaging targets at extended range — all without tools or removing hands from the weapon.Daytime PID and training. The green laser at 5 mW provides confident daylight visibility at 100+ m. Low-power mode (1 mW, Class II) is safe for indoor range use.What's in the BoxHolosun IRIS-GR3 moduleDual-button remote switch with Crane plug and VIS override functionPicatinny / Weaver mounting clampCR123A batterySoft carry caseAdjustment toolManual and warranty cardBuy at Professional OpticsThe Holosun IRIS-GR3 is available at Professional Optics in Split, Croatia, with competitive pricing and fast shipping across Europe.
