Primary Arms GLx 2X Prism with ACSS-M5 5.56/.308/5.45 Reticle

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.

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!

Insanely good quality prisim sight, works out to 150 yards easily and works in room distances easily. Always always go with a prison optic over a red dot any day of the week.

Perfect scope for 22 or rifle for 75 yds and in, on a light weight Ruger 10/22 carbon fiber, both eyes open. I tend to like ar scopes on 22 rifles.

This is the best optic for an AR

Bridges the gap between red dot and lvpo. Can “almost” be both. I really like it. Also It can be used with a2 front sight

Once you sight this in at 50yrds with 5.56... this optic is just so easy to use with this reticle. Eye relief is very forgiving if you aren't close enough, probably 4in of eye relief. You also get 3 different height mounts and screws for other mounts you might have.

Couldn’t remove the mount screw. I’m not new to this, and sacrificed two tools to the screw. Either the grizzly bear that installed this or the threadlocker beat me. The provided wrench was a sloppy fit and stripped immediately, although it was under very high torque when it did so. This may have rounded the screw enough to make my personal tools less effective. I’ll never know, much like I’ll never know how this shoots. Bummer. Great glass and VERY bright. Can’t imagine how people aren’t satisfied with brightness. Hopefully QC doesn’t miss yours. I’m convinced that this is very likely a great tool, mine just sucked. Oh well. ETA: before returning I broke down and tried one more high quality wrench. Ruined one more, high quality, wrench.

Très bon scope... Rien de négatif à dire...
