Primary Arms SLx 5X MicroPrism™ Scope - Red Illuminated ACSS Aurora MIL Reticle



*Lead time is 5-10 business days


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. 

For precision without compromise, the SLx 5x MicroPrism brings an extended range to this lightweight, ultra-compact design. Weighing only 8.5oz with a 3.31" overall length, the SLx 5x MicroPrism is comparable to many red dot sights, though its crystal-clear glass and 5x magnification offer improved precision at even longer distance than the 3x variant. 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 5x 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.
