Description
The Primary Arms SLx 5X MicroPrism Scope is a compact fixed-5x prism scope that delivers real mid-range magnification and a precise MIL reticle in a tiny 3.31in, 8.5oz package. Because the ACSS Aurora MIL reticle is etched into the glass, it stays crisp and fully usable even with the illumination off — a big advantage for shooters with astigmatism, who often see red dots as a smear.
The MIL-based reticle provides a full grid for ranging, elevation and wind holds. Red illumination spans 13 settings (3 NV-compatible) with AutoLive motion-sensing to save battery, and it ships with a modular mount offering 8 height options.
