Primary Arms GLx 1x MicroPrism ACSS Cyclops Red Prism Sight

Prism sights solve a problem a red dot cannot. The reticle is etched into the glass, so it still gives you an aiming point if the illumination dies, and it stays crisp for shooters with astigmatism who see a smear instead of a dot. The GLx 1x MicroPrism is the upgraded version of that idea from Primary Arms, with push button controls, a daylight bright reticle and near unlimited eye relief that keeps it from being fussy about where it sits on the rail.

The ACSS Cyclops reticle pairs a large surround with a center aiming point, so it reads fast up close and still gives something precise to hold with at distance. The 8 position mounting system lets you set the optic at the height your cheek weld and host gun want instead of shimming a mount to fit. It is compact enough to leave rail space for a magnifier behind it or a light out front.
