Reviews & Ratings for Primary Arms The SLx 1x23mm Mini Red Dot Reflex Sight — 12 reviews — Page 1

No complaints. Like that a Glock adapter plate is included.

With a little bit of common sense, this optic mounts easily to the Glock 40 MOS with the provided low mount. The bolts are easily identified, The shortest bolts attach the mount to the MOS Glock, the next length up attaches the optic to the mount. The screws already have blue loctite on them.
I ran about 100 rounds through the pistol with no issues. The factory sights sit just below the window, they don't cowitness but, I was able to get a pretty good idea of where the factory sights line up and was able to sight in the optic at home, no adjustment needed at the range. I didn't have the same problems as I've heard others complain about with this optic. Seems to be a pretty good optic for the money.

Solid optic for my use case (backup red dot) but a vertical reflection of the emitter makes using on pistols difficult. If you accidentally look too high above the red dot projection, you'll see a smaller red dot projected, causing you to shoot like 60 moa low of the intended target. This can definitely happen if you're shooting a pistol, but is pretty rare to be so off axis for a rifle red dot. Also many mounting platforms use 6-32 screws which are too big for the holes in the red dot - you'll need to run a 5/64" drill through the holes to accommodate the standard size. Finally, the external dimensions of the doctor footprint are a little larger than the standard doctor footprint. If you're using the doctor plates for an m&p 2.0 core, you'll need to file off some of the plastic on the mounting plate. On the other hand, it's cheap, it holds zero, and it has shake awake.

Overall I am totally satisfied.

Construction
- I have not had it long, but optic feels durable
- battery tray, while not tool less, is simple and works well.
- brightness adjustment is easy to use.

Dot
- I have some degree of astigmatism, but the 3moa mitigates much of the starring I have experienced with 2moa dots. (6moa is the best for astigmatism, but I prefer a 3moa for competition)
- I have experienced no zero shift so far.
- there is a small amount of "flicker" or "tracing" with fast movement, but imo not an issue.

Looks cool too :)

For context - I also ordered a Romeo 2 pro 6moa (on sale blem), which was a little more cumbersome to use (battery tray was tricky, brightness adjustment pretty cumbersome) and while its a really nice dot and versatile optic with included shrouds, its a little large for my taste and the cumbersome controls kind of deterred me... not to mention the price point.

Overall I would recommend this optic!

This is a very useful and Heavy-duty red dot for the price and it has a assume automatic on sencer great feather

For the price this optic is holding up so far. Even comes with a really slim plate for MOS system used glocks love how low it sits for absolute cowitness

Ultimately, the optics does what it says on the tin so read the specs sheet and make sure you are happy with what it contains. It's OK if you catch it on sale. I haven't noticed a refresh rate issue like some have mentioned. I was disappointed that the tall housing doesn't translate to more usable space. The dot becomes distorted and disappears in the top of the housing. Oh, and to turn off the optic you have to very precisely press both brightness up and down buttons at the same time and hold them for 3 seconds. Very clunky, but you only have to do it once a range trip.

The product arrived well packaged and delivered within the expected time frame however it came with the battery installed indicating that the product was likely a floor model or worse, a return. It wasn't readily apparent the optic was "used" or otherwise "not new" at the time of purchase however, it did power on/off as expected. I haven't attempted to zero the device as of this review but will update the review if it fails to zero.

The product seems well built and supports the majority of positive reviews. I've ordered several other products from Optics Planet all to great satisfaction and will likely continue to purchase from this site in the future. Lastly, regardless of the apparent "not new" condition I would not expect a product of this type to be shipped with the battery installed without knowing the reason at the time of order. Minus one star for battery installed prior to shipping.

I've purchased 2 of these now and may do a third soon. I have one direct mounted to a masasda and the other I have on a KP9 with the picatinny attachment. Honestly, they are great for the price, perform well, I love the autolive as well. Good window size, what's there not to like?

I bought this to piggyback on my Vortex Spitfire because there aren’t a ton of options for that footprint. And because I’ve always loved Primary Arms optics. This red dot is good for $200 but I expected a tiny bit more. The reticle itself could be just a little sharper - it looks like 4 MOA instead of 3 (but that could maybe just be my eyes even though other red dots look fine to me). Also, while I’m sure it’s very durable, I dropped it just a few inches while it was mounted to my rifle and it got scuffed up pretty bad. That’s not an issue for me, but I’m sure it would be for some people. All in all, I’m happy with this optic but I’m keeping my eyes open for other options with this footprint.
