It is 2.48 in (63 mm) long, weighs 5.5 oz (156 g), adjusts in 1 MOA clicks with 120 MOA of total travel, gives a 76.5 ft field of view at 100 yards (25.5 m at 100 m), and is sealed to IP67.\u003c\/p\u003e\u003cp\u003eThe ACSS Gemini 9mm is calibrated specifically for 9mm from barrels of 7.5 to 16 inches (191 to 406 mm), with bullet drop references out to 200 yards, ranging, moving-target leads and a bold outer horseshoe around a precise centre chevron.

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 is the T-Dot reticle?\u003c\/b\u003e\u003cbr\u003eThe T-Dot is a deliberately simple etched reticle giving a clean central aiming point with a post beneath it, chosen by shooters who want speed rather than the ranging stadia and holdover marks of the ACSS reticles.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhat mount does the SLx 1X MicroPrismT need?\u003c\/b\u003e\u003cbr\u003eThe SLx 1X MicroPrismT uses the H1\/T1 micro-dot footprint, so it fits the wide range of mounts made for micro red dot sights, and a 2.26 in mount is supplied in the box.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDoes this optic work if the battery dies?\u003c\/b\u003e\u003cbr\u003eYes.

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\u003eWhy choose green illumination over red?\u003c\/b\u003e\u003cbr\u003eThe human eye is most sensitive to green light, so a green reticle is often easier to pick up against foliage and in poor light, and it can be seen clearly at a lower brightness setting, which saves battery.\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\u003eDoes the Primary Arms GLx 1X MicroPrism work if the battery dies?\u003c\/b\u003e\u003cbr\u003eYes.

It is 2.95 in (75 mm) long, weighs under 7.95 oz (225 g), adjusts in 1\/4 MOA clicks with 80 MOA of windage and elevation travel, gives a 38 ft field of view at 100 yards (12.7 m at 100 m), and runs up to 29,000 hours on a CR2032 cell across 13 brightness settings, three of which are night-vision compatible.\u003c\/p\u003e\u003cp\u003eA prism scope solves a problem a red dot cannot. In a red dot the aiming point is a projected LED, and an eye with astigmatism sees that point of light smeared, flared or doubled — which is why some shooters never get on with red dots and assume the fault is theirs. In a prism scope the reticle is physically 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. If red dots have always looked like a comet to you, this is the class of optic to try.\u003c\/p\u003e\u003cp\u003eThe etched reticle also stays fully usable with the illumination switched off or the battery flat, which no red dot can claim, and AutoLive motion sensing keeps the cell alive by shutting illumination down when the rifle is still.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHow It Compares\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eThis is the red-illuminated black 3X.

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"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/2005\/3592\/collections\/hf_20260831_213415_e8c03db1-c81f-4015-bdac-f2b5bbcede4c.png?v=1789011211","url":"https:\/\/opticstrader.co.uk\/collections\/primary-arms-prism-scopes.oembed","provider":"Optics Trader","version":"1.0","type":"link"}
