Description
The Primary Arms GLx 1X MicroPrism Scope scope is the premium step up from the SLx prism line — a bigger 20.5mm window, near-unlimited eye relief and improved daylight-bright illumination. Because the ACSS Cyclops reticle is etched into the glass, it stays usable even with the illumination off, ideal for shooters with astigmatism.
The Cyclops reticle combines a fast horseshoe and precise centre chevron with built-in ranging, while push-button controls drive 13 settings (3 night-vision) and AutoLive saves battery. It ships with a modular mount offering 8 height options.
