This Primary Arms MicroPrism is part of the SLx optics line. SLx optics have built a 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 and features crystal-clear glass with 3x magnification for improved precision at distance. Even in close-quarters, the optic's 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. 13 Illumination settings + 3 NightVision; Highest settings are Daylight Bright AutoLive motion-sensing on/off battery saving technology Length: 2.95 Weight: < 7.95 oz.
