After rigorous field testing, this optic has been given a silver-tier rating by the National Tactical Officers Association.
This Primary Arms MicroPrism is part of the SLx optics line. SLx optics built their 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. 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.
