Primary Arms Optics SLx 3X MicroPrism ACSS Raptor 5.56/.308 FDE Prism Scope

The Primary Arms SLx 3X MicroPrism is a compact, fixed-magnification prism optic built around the popular ACSS Raptor reticle. This version is calibrated for both 5.56 NATO and .308 Winchester and is graduated in 100-yard increments, with chevron-style auto-ranging ballistic holdovers that let the shooter pull distance quickly without leaving the reticle.

The SLx 3X MicroPrism pairs a 3X fixed magnification with a 23mm objective in a package measuring just 2.95 inches long and weighing under 7.95 ounces. The body is finished in Flat Dark Earth to pair naturally with FDE rifles and chassis, and the housing is machined to drop directly onto any Mini-ACOG-pattern mount, giving the optic a familiar scout-style footprint across a wide range of carbines and DMRs.

This 710054 variant is the red-illuminated configuration of the SLx 3X MicroPrism. It offers 13 daylight illumination settings plus 3 night-vision-compatible brightness levels and uses Primary Arms' AutoLive motion-sensing technology to switch the reticle on and off automatically, preserving battery life between engagements. The combination of an auto-ranging reticle, daylight-bright illumination, and a sub-8-ounce housing makes the SLx 3X MicroPrism a strong primary or offset optic for 5.56 and .308 rifles where speed and weight savings matter.
