Primary Arms SLx 1X MicroPrismT ACSS Gemini 9mm Green H1/T1 Prism Sight (Primary Arms, SKU: PA-SLX-1XMP-H-9MM-G) is a compact fixed 1× prism sight designed for 9mm pistol-calibre carbines. The glass-etched ACSS Gemini reticle remains visible without power, while green illumination improves its visibility in varying lighting conditions. The MicroPrismT version uses the Aimpoint Micro H1/T1 mounting footprint.
