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! Review: Great optic! 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. ## Features - Glass etched reticle that works with illumination on or off - Daylight Bright full reticle illumination with 11 settings, CR2032 battery provides up to 20,000 hours of reticle illumination at medium settings - Forgiving eye box with 3.5” of eye relief, and a bright 12mm exit pupil - Patented ACSS CQB M5 5.56 reticle provides fast target acquisition, range estimation, and moving target leads out to 500 yards. - Quick adjust diopter ring for shooter-optimized reticle focus, Wide 42-foot field of view at 100 yards ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09NS1GQPC | | Best Sellers Rank | #202,798 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #454 in Rifle Scopes | | Brand Name | Primary Arms | | Color | Black | | Compatible Devices | Rifle | | Customer Reviews | 4.6 4.6 out of 5 stars (51) | | Field Of View | 42 Feet | | Item Weight | 11 ounces | | Magnification Maximum | 2 x | | Magnification Minimum | 2 x | | Manufacturer | Primary Arms | | Material Type | Aluminum | | Mounting Type | Picatinny Mount | | Night vision | No | | Objective Lens Diameter | 12 Millimeters | | Product Style | Rifle Scope | | Reticle Type | ACSS CQB-M5 5.56 | | Sport Type | shooting | | UPC | 818500015062 | | Warranty Description | Limited Lifetime | ## Product Details - **Brand:** Primary Arms - **Color:** Black - **Compatible Devices:** Rifle - **Item Weight:** 11 ounces - **Magnification Maximum:** 2 x - **Magnification Minimum:** 2 x - **Material:** Aluminum - **Objective Lens Diameter:** 12 Millimeters - **Sport:** shooting - **Style:** Rifle Scope ## Images ![GLx 2X Prism with ACSS CQB-M5 5.56/.308/5.45 Reticle - Image 1](https://m.media-amazon.com/images/I/819JOxXr3pL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ PA Really Nailed it With This Optic & It’s a Great Solution for People with Ageing Eyesight *by M***N on July 23, 2023* 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.
