Primary Arms Optics SLx 5x MicroPrism Features The Primary Arms Optics SLx 5x MicroPrism uses an internal glass prism and an etched ACSS Aurora 5.56 Yard reticle to deliver a crisp parallax-free sight picture from 50 yards to infinity. Because the reticle is etched into the glass rather than projected electronically it remains visible and usable even if the CR2032 battery is fully depleted a clear reliability advantage over standard red dot sights. The reticle illuminates in red across 9 daylight-bright settings and 3 night vision compatible settings letting the shooter match brightness to any ambient light condition. AutoLive motion-sensing illumination technology automatically manages power use contributing to an exceptional runtime between 25 001 and 50 000 hours on a single CR2032 battery. At just 8.50 ounces and 3.31 inches in overall length the SLx 5x MicroPrism brings 5x magnification into a footprint comparable to many red dot sights with a 2.70 inch eye relief and a 21 foot field of view at 100 yards for fast target acquisition. The included ruggedized mounting system uses an industry-standard mini-prism footprint compatible with the MR12 12 O Clock Mini Reflex Mount and MDOM Offset Micro Dot Mount and can be set to 8 different mounting heights and configurations. Finished in a hardcoat anodized Black housing with 50 MOA of windage and elevation adjustment the optic is built to withstand heavy use and adverse field conditions. Complete with a lens cover the Primary Arms Optics SLx 5x MicroPrism is available for sale at GrabAGun.
