This Microprism is part of the SLx optics line. SLx optics built the reputation for innovation, reliability and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment.The SLx 3x MicroPrism is an all-new advanced optical system that combines the compact, lightweight size of a microdot with the durability and precision of a 3x magnified optic. The SLx 3x MicroPrism offers 13 illumination settings with AutoLive motion-sensing on/off technology and multiple night vision compatibility options.Weighing under 8oz, the SLx 3x MicroPrism is smaller and lighter than many red dot sights, though its crystal-clear glass and 3x magnification offer improved precision at distance. Even in close-quarters, the optics wide field-of-view and forgiving eye relief make it easy to snap on target.Because the SLx 3x MicroPrism uses an etched reticle with adjustable diopter, the user will always have a clear, crisp reticle image, even if they have severe astigmatism. When set to max illumination, the MicroPrism reticle is fully daylight bright. For low-light, this optic offers 3 different NV-compatible settings, accommodating any ambient light level. Paired with the AutoLive motion-sensing illumination technology, this optic provides an exceptionally long runtime at any brightness setting.This package also includes the new ruggedized mounting system with industry standard mini-prism footprint, guaranteeing reliability and zero retention through heavy use and adverse conditions. Out of the box, this mount can be set for 8 different mounting heights and configurations, ensuring compatibility with any rifle system.Specifications for Primary Arms SLx 3x MicroPrism Red Dot Sight:Manufacturer:Primary ArmsFabric/Material:AluminumMagnification:3 xObjective Lens Diameter:17 mmIllumination Type:LEDEye Relief:2.7 - 3 inAdjustment Type:MOAAdjustment Click Value:0.25 MOAField of View, Linear:38 ft at 100 ydsAttachment/Mount Type:PicatinnyBattery Type:CR2032Battery Quantity:1Water Resistance Level:WaterproofShockproof:YesFogproof:YesGun Make:AR PlatformGun Model:AR-15Weight:7.95 ozExit Pupil:10.3 mmFeatures of Primary Arms SLx 3x MicroPrism Red Dot Sight13 Illumination settings + 3 NightVision; Highest settings are Daylight BrightAutoLive motion-sensing on/off battery saving technologyLength: 2.95 Weight:Package Contents:Primary Arms SLx 3x MicroPrism Red Dot SightPrimary Arms 710037: SLx 3X MicroPrism Red Dot Sigh, Green Illuminated ACSS Raptor 5.56/.308 Reticle - Yard, BlackPrimary Arms 710040: SLx Series MicroPrism Red Dot Sigh, 3x, ACSS Raptor 7.62 YP Illuminated Reticle, BlackPrimary Arms 710036: SLx Series MicroPrism Red Dot Sigh, 3x, ACSS Raptor 5.56 YP Illuminated Reticle, BlackPrimary Arms 710041: SLx 3X MicroPrism Red Dot Sight, Green Illuminated ACSS Raptor 7.62x39/300AAC Reticle - Yard, BlackPrimary Arms 710038: SLx 3X MicroPrism Red Dot Sigh, Red Illuminated ACSS Raptor 5.56/.308 Reticle - Meter, BlackPrimary Arms 710054: SLx 3X MicroPrism Red Dot Sigh, Red Illuminated ACSS Raptor 5.56/.308 Reticle - Yard, Flat Dark EarthPrimary Arms 710057: SLx 3X MicroPrism Red Dot Sigh, Red Illuminated ACSS Raptor 7.62/300BO Reticle - Yard, Flat Dark EarthPrimary Arms 710037: SLx 3X MicroPrism Red Dot Sigh, Green Illuminated ACSS Raptor 5.56/.308 Reticle - Yard, Black
