Description
The Primary Arms SLx 1X MicroPrism Scope with the red ACSS Gemini 9mm reticle is a compact prism scope built for 9mm pistol-calibre carbines — red-dot speed with the clarity and durability of an etched glass reticle that stays sharp even for shooters with astigmatism. It uses the H1/T1 micro-dot footprint.
The ACSS Gemini 9mm reticle is calibrated for 7.5–16in 9mm barrels, with a centre chevron, bullet-drop references to 200 yards, ranging and a bold outer horseshoe for fast close-range pickup and moving-target leads. Red illumination across 13 settings (3 NV), AutoLive motion activation, and an IP67 nitrogen-purged body. Ships with the 2.26in mount.
