After rigorous field testing, this optic has been given a Silver-tier rating by the National Tactical Officers Association. The SLx 1x MicroPrism is an all-new advanced optical system 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. 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 the new ruggedized mounting system. Out of the box, this mount offers 8 different mounting heights and configurations. The SLx 3x MicroMagnifier is an exciting approach at optical magnifiers, combining high-clarity 3x magnification with a miniaturized body. Weighing only 5.3 oz, the SLx 3x MicroMagnifier is a miniaturized, lightweight magnifier that extends the effective range of a red dot sight or 1x prism scope. The SLx 3x MicroMagnifier features an innovative ‘micro-sized’ design that reduces its footprint compared to traditional magnifiers. The Primary Arms SLx Flip-To-Side Magnifier Mount is designed to place your magnifier at 1.41 inches above the top of the picatinny rail. Additionally, it includes spacers allowing for a 1.535" and 1.64" centerline height, so you can easily line it up with your optic. It features a low profile design manufactured from 6061-T6 aluminum with two steel alloy crossbolts that apply up to 55 in-lbs or torque to ensure a rock solid mount.
