Primary Arms SLx 1X MicroPrism ACSS Cyclops is a compact 1× prism sight, part of the respected SLx line known for reliability, innovation, and value. Field-tested on a SCAR 17 .308 Win with over 7,000 rounds fired without damage.

It features an improved ACSS 5.56 etched reticle on low-dispersion glass, AutoLive illumination, and reinforced mount for a solid, reliable fit on the firearm.

The SLx 1x prism sight is ideal for fast, both-eye shooting at close range. Astigmatic shooters often experience blurred or distorted points with red dots; prism sights resolve this issue efficiently.

Unlike red dots, prism sights offer a BDC reticle with clear parallax-free image, precise medium-range shooting, and binocular aiming while maintaining situational awareness.

The sight has a sealed aluminum IP67-rated body, 10.3 mm exit pupil, and generous eyebox for quick aiming without exact optical alignment. ACSS Cyclops Gen II 5.56 / .308 etched reticle is visible even without illumination. Under the reticle is a range scale. The green reticle (horseshoe and chevron) has 13 daylight + 3 night levels. AutoLive motion sensor extends battery life — up to 29,000 hours at medium brightness. AutoLive shuts off illumination when idle and reactivates on movement.

The ACSS Cyclops Gen II reticle features a central thin chevron surrounded by a thick horseshoe, with drop compensation and range estimation marks, ideal for dynamic short-range and precise medium-range shooting.

SLx 1X MicroPrism has a sturdy aluminum mount with steel components, ensuring stable zero retention. Included are two risers (Absolute Cowitness and Lower 1/3) for optimal mounting height.
