Primary Arms SLx 1x MicroPrism with Red Illuminated ACSS Cyclops Reticle

Primary Arms SLx 1x Features and Performance

The Primary Arms SLx 1x is a compact prism optic designed for fast target acquisition, durable performance, and practical versatility on rifles and carbines. Built around a 1X prism scope design, it offers many of the speed advantages shooters want in a close-range optic while also providing the clarity and reticle definition that make prism sights especially appealing for general-purpose rifle setups.

This optic uses the ACSS Cyclops G2 reticle in red, giving shooters a refined aiming system that is more informative than a basic dot sight. Because it is a prism scope, the etched reticle remains usable even without illumination, while the partial illumination system adds visibility in a wide range of lighting conditions. That makes the Primary Arms SLx 1x a strong choice for range use, defensive carbines, and shooters who want a compact optic with a practical reticle layout.

The sight picture is built around a 15.6 mm exit pupil and a 76.50-foot field of view at 100 yards, helping create a fast and usable view for close and intermediate-range shooting. Night vision compatibility adds flexibility for more advanced setups, while 1 MOA click adjustments and 120 MOA of both elevation and windage adjustment provide plenty of room for zeroing across a variety of rifle platforms.

Powered by a CR2032 3V lithium coin battery, the Primary Arms SLx 1x offers a battery life rated from 25,001 to 50,000 hours. At just 7.6 ounces and 2.48 inches in length, it remains compact and manageable while still delivering the solid feel expected from a prism optic. With compatibility for Trijicon Mini-ACOG and Primary Arms MicroPrism mounts, it is a practical option for shooters who want a lightweight and capable prism sight for everyday rifle use.
