Overview
The Primary Arms SLx 1x MicroPrism is a true 1x prism optic for shooters whose red dot looks like a smeared comet instead of a clean point. The ACSS Cyclops Gen II reticle is etched into glass rather than projected as one LED point, can be focused with the diopter, and remains usable with a dead battery.
At 5.5 oz without the riser and 2.48 inches long, the 1x MicroPrism is close to red dot size and weight. The ACSS Cyclops Gen II reticle pairs a central chevron with a surrounding horseshoe for fast close-quarters acquisition and a usable holdover system out past 300 yards. The optic mounts on the included absolute and lower-third co-witness heights, and Primary Arms also offers an H1/T1-footprint version for shooters who already own red dot mounts.
A CR2032 battery powers the illumination, and the etched reticle backstops it when the battery dies. The 1x MicroPrism is the choice for a shooter who wants the snap-shooting speed of a 1x optic but cannot run a conventional red dot because of astigmatism, and it accepts a magnifier behind it for stretching range.
