This Microprism is part of the SLx optics line. SLx optics built our reputation for innovation, reliability and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment.
The SLx 1x MicroPrism is an all-new advanced optical system designed from the ground up in an ultra-compact housing, allowing use of backup iron sights and magnifiers. Using cutting-edge LED technology, the SLx 1x MicroPrism offers 13 illumination settings with AutoLive motion-sensing on/off technology and three night vision settings. At maximum illumination, the MicroPrism offers true daylight bright performance, while the innovative low-power sleep mode safeguards battery life for reliable ‘always-on’ storage. Though small in size, virtually no sacrifice was made for eye relief and even offers a generous field of view. This package also includes a 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 offers 8 different mounting heights and configurations, ensuring compatibility with any rifle system.
