It is 2.6 in (66 mm) long, weighs 9.1 oz (258 g), adjusts in 1\/2 MOA clicks with 50 MOA of windage and elevation travel, gives a 74.8 ft field of view at 100 yards (24.9 m at 100 m), and runs approximately 14,925 hours on a CR2032 cell at setting 5, with 13 brightness settings of which 3 are night-vision compatible. The housing is nitrogen-purged and sealed to IP67.\u003c\/p\u003e\u003cp\u003eThis is the premium prism in the range and the answer for anyone who wants red dot handling without red dot optics. The 20.5 mm window is noticeably larger than the SLx prisms, eye relief is near-unlimited so head position is forgiving, and the ACSS Cyclops reticle pairs a fast horseshoe with a precise centre chevron and built-in ranging. Crucially the reticle is etched into the glass, not projected — so an eye with astigmatism sees a clean chevron rather than the smeared comet a red dot produces, and the reticle still works with the illumination off.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHow It Compares\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eThis is the premium 1x prism with red illumination.

A prism scope's reticle is etched into the glass and viewed through the optic's own focusing system, so it is resolved by the same corrected optical path as the target, whereas a red dot projects an LED that an astigmatic eye commonly sees as a smear, flare or double image.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhat does the ACSS Cyclops reticle do?\u003c\/b\u003e\u003cbr\u003eThe ACSS Cyclops combines a bold horseshoe that draws the eye to the centre quickly at close range with a precise centre chevron for accurate aiming and built-in ranging references for estimating distance to a target of known size.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHow is the GLx 1X MicroPrism different from the SLx version?\u003c\/b\u003e\u003cbr\u003eThe GLx 1X MicroPrism has a larger 20.5 mm window, near-unlimited eye relief, improved daylight-bright illumination and IP67 nitrogen-purged sealing, sitting above the SLx prism line in specification.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDoes the Primary Arms GLx 1X MicroPrism work if the battery dies?\u003c\/b\u003e\u003cbr\u003eYes. The ACSS Cyclops reticle is etched into the glass rather than projected, so it remains fully visible and usable with the illumination switched off or the battery flat.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhat mount does the GLx 1X MicroPrism need?\u003c\/b\u003e\u003cbr\u003eThe GLx 1X MicroPrism ships with a modular mount offering 8 height options on the Trijicon Mini-ACOG and Primary Arms MicroPrism footprint, so no separate mount needs to be bought.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eIs the GLx 1X MicroPrism waterproof?\u003c\/b\u003e\u003cbr\u003eThe Primary Arms GLx 1X MicroPrism is sealed to IP67 and nitrogen-purged, which protects it against dust ingress, temporary immersion in water and internal fogging.\u003c\/p\u003e","brand":"Primary Arms","offers":[{"title":"Default Title","offer_id":58434901836120,"sku":"PA-GLX-1XMP-CYCLOPS","price":349.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/2005\/3592\/files\/primary-arms-glx-1x-microprism-acss-cyclops-1.jpg?v=1789007617","url":"https:\/\/opticstrader.co.uk\/products\/primary-arms-glx-1x-microprism-acss-cyclops","provider":"Optics Trader","version":"1.0","type":"link"}
