The GLx 2x Prism won the editors’ trust for its combination of form factor, innovation, and reliability. The Primary Arms GLx 2X Prism Scope combines premium glass quality and our popular ACSS reticles in a ruggedized, compact form. This fixed power optic provides enough magnification to enhance target identification, yet allows for seamless both-eyes-open, red dot style shooting at close-range targets. The compact body is 5.3” long and weighs in at 11.0 Oz with 3.5 inches of eye relief and a 12mm exit pupil. With Daylight Bright illumination, a 20,000-hour battery life, and AUTOLIVE motion activation and the GLx 2X Prism Scope is sure to be a new favorite in your collection. This optic also comes equipped with our next-generation ruggedized mounts. These mounts offer exceptional clamping power with hardened steel hardware, ensuring they will not move when properly torqued. This GLx 2X Prism Scope features our patented ACSS CQB-M5 5.56 reticle, combining bullet drop compensation, automatic ranging, and, moving target leads, and a fast acquisition horseshoe in one quick and intuitive package! For close range targets, the large outer horseshoe quickly grabs the eye and encourages quick target acquisition, while the center chevron allows for impressive precision at distance. The integrated BDC system offers holdovers for targets out to 500 yards and has been tuned for 5.56 NATO, 5.45x39mm, 6.8 SPC, 6.5 Grendel and some .308 Winchester loads. This BDC includes auto-ranging stadia, so users can determine target distance and engage with peerless accuracy!

Don’t sit on the fence any longer - This is a quality optic all the way around from glass quality to eye relief. I never owned an optic with this type of reticle but I really like how sharp it is. It took me only 15 minutes of practice after setting the diopter to my eye to focus on the reticle be able to pull it up to my eye quickly and have my eye pick it up even indoors at close range. Review: PA Really Nailed it With This Optic & It’s a Great Solution for People with Ageing Eyesight - I’ve always loved my Aimpoint Micros and other collimator type of optics, but at this point, worsening astigmatism has made them nigh impractical for me. Luckily, I found that this optic is a very viable replacement. The low magnification, combined with the excellent daylight-bright reticle, generous eye box/relief and a very wide FOV, allow me to engage CQB targets almost as fast as I was doing with my red dots and holos, while the magnification also makes precision hits on medium and long-range targets easier. Despite having lower magnification, the clarity of this glass lets me make out fine details better than I can do with my cheaper 3X prisms. The adjustable diopter offers a tangible advantage over even the much more expensive optics like ACOGs. In addition, this optic is built sturdy (though no ACOG-sturdy), looks pretty sexy and doesn’t add too much weight to your rifle. The battery life is the best in its class, combined with a “Shake Awake” feature. Also, the etched reticle makes this optic usable even without a power source, offering a good choice for “preppers” concerned about things like battery availability and EMP. As always, PA shipping was quick and everything was well-packaged, with a bunch of free stickers and such. The included mount seems pretty good, is removable and the package includes all kinds of different risers. I’ve always used QD mounts for collimating and low mag optics and thus, paired this scope with an American Defense ACOG Micro QD Mount. I had no problem removing the factory mount and installing the AD with an appropriate riser. This optic required very few adjustments when I was laser bore sighting it in my garage. The adjustment knobs are solid, with very positive clicks. Taking this scope out to the range on top of my new BCM upper, it took me less than half a box of 77 gr OTMs to get it to the point of shooting rounds through the same hole on a bullseye of a 50-yard paper target. I don’t think that I have ever zeroed a scope this quickly! Anyhow, the only “negative” I can say is that buying this optics is ending up costing me quite a bit of money, because I now need more of them for my other rifles. Luckily, you can get three of these for the price of a single ACOG 1.5X! Good job, PA! ## Features - ACSS CQB-M5 5.56 reticle: Glass-etched reticle perfect for astigmatism; functions with or without illumination and combines a fast-acquisition horseshoe, center chevron, BDC holdovers, auto-ranging stadia, and moving target leads; 1/4 MOA capped turrets with 40 MOA of total windage and elevation travel - Forgiving eye box and wide field of view: Measures 5.3 inches in length and weighs 11.0 oz with 3.5 inches of eye relief and a 12 mm exit pupil for an exceptionally wide, forgiving sight picture. 42.0 feet field of view at 100 yards supports fast both-eyes-open target acquisition at close range and extended distances; adjustable diopter ring for shooter-optimized reticle focus - AutoLive with 11 Daylight Bright illumination AutoLive: Red illuminated reticle cycles through 11 brightness levels reaching true Daylight Bright at maximum output for clear reticle visibility in direct sunlight.
