Primary Arms SLx MicroPrism 3x Red Dot - ACSS RAPTOR 5.56 - This MicroPrism is part of SLx optics line. SLx optics built Primary Arms' 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 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.
