Primary Arms GLx 1x MicroPrism ACSS Cyclops Gen 3 Red Prism Optic

The Primary Arms GLx 1x MicroPrism is a compact fixed-1x prism sight purpose-built for fast, both-eyes-open close-to-mid-range shooting. Featuring a 20.5mm objective lens and an updated internal optical design, the GLx delivers improved edge-to-edge clarity over earlier Primary Arms MicroPrism offerings while keeping a remarkably small footprint at just 2.6" long and 9.1 oz.

At the heart of the optic sits the ACSS Cyclops Gen 3 reticle - a red-illuminated horseshoe-and-dot pattern calibrated for rapid target acquisition and intuitive holdovers. The GLx offers 13 illumination settings paired with Primary Arms' AutoLive motion-sensing on/off technology, plus 3 night-vision-compatible brightness levels for use with NV devices.

Built around a durable aluminum housing in a black finish, the GLx 1x MicroPrism provides a generous 4.4" of eye relief, a wide 74.8 ft @ 100 yds field of view, an 18.8 mm exit pupil, and 50 MOA of total windage and elevation adjustment in precise 1/2 MOA clicks.
