    Amazing quality

    Posted by AZ Shootist on 6th Aug 2025

    As a retired gunsmith and gunshop owner, I've had my hands on a LOT of optics over the past 34 years. I read a bunch of reviews before deciding to try the Ade Micro Red Dot Site. I had used their mounts in the past and was impressed with their precision and quality. The site did not disappoint and was simple to mount on a Beretta M-92FS (using the appropriate Ade mount). The lens is nicely coated, the dot is clear and fully adjustable and the thing just looks awesome...and at a price that is half that of comparable sites. I am so impressed that I just ordered another one to attach to a custom M-1911 "Race Gun".

    Great mid entry level pistol red dot

    Posted by RR on 6th Aug 2025

    Bought this for my FN Herstel FNX .40s&w. Initial quality is good. It's a bit rough around the edges on the aluminum frame and the optic. with that being said; I was able to zero this in at 10yds at the range with one clip and it holds true. Optic is clear and the coating filters out extra bright light and looks great.

    Value for the buck

    Posted by reynaldo pina on 6th Aug 2025

    This little guy surprised me! I wasn’t expecting much for the price, but the sight was actually pretty good. The sight was clear, the design was pretty good, and overall easy to install and zero. I like that the battery cover is on to make it it easier whenever the time comes to replace the battery. 6moa is a bit on the bigger side but overall I enjoy it.

    Great Red Dot Sight

    Posted by STAR Financial Credit Union on 6th Aug 2025

    This is a excellent sight and relatively easy to install. Removing the attached pic base only took a couple of minutes to figure out and other than that it was easy. This is a great value and it compares well with my other red dot sights. I like this better than my EOTech red dot sight!

    Love this

    Posted by FrickelSnitz on 6th Aug 2025

    Really cannot wait to shoot with this. This is my first red dot and after doing some research I realized I did not need to spend bookoo $$ to get a good quality sight. I’m very happy with how this appears to look and I like the top battery mount and the adjustments. Easy to turn on and off and adjust as well. American flag is cool to see :) very happy here

    Fits Canik TP9 sfx

    Posted by Dom on 6th Aug 2025

    Fits well though I think the screw hardware on my Canik mount was a little screwed up. Had to use the Canik screw for right side screw. Left side screw worked for the ADE screw. Will update if anything goes wrong. This feels like more of a target range sight. Having to hold the button for 3 seconds to turn it on would be a real downside if I were in any kind of an extreme situation.

    Buy This First Before You Spend a LOT of $$$

    Posted by HO-YOUNG C. on 6th Aug 2025

    This is a great Red Dot for new Red Dot owners. Don’t spend high dollars for an RMR or DP Pro if you’re just getting started with red dot shooting. Try this one first! It works just as good as those mentioned. Those that are saying it comes with a big thick base, just take the base off and it will mount flush onto your pistol Sight plate. This has a very low profile! Works perfectly on my Walther PPQ Match Q5! Very well built! For the price, I’m very impressed with what I got!

    These Ade red dots are a hidden gem this was my 5th one never a problem with any of them!

    Posted by JIMBO on 6th Aug 2025

    If you think because of the price these are not good red dots you're slowly mistaken I don't know about any of the negative reviews but as my I have 5 of these I've used them on multiple kinds of handguns and even have 1 on a AR-15 And no problems with any of them they hold zero and as long as you use a little blue Loctite their plates and their red dot screws won't loosen up??

    5.0 out of 5 stars Great red dot for plinking

    Posted by Shane on 6th Aug 2025

    Currently have it installed on a S&W Victory 22, sight is nice and lightweight. Easy to zero and holds it very well, though it’s not getting beat too hard with just a .22lr so your mileage may vary. Would I put this on my AR15 pistol? Probably not. A 22 or 9mm carbine? Absolutely. My only minor complaint is that the screw head for the picatinny mount sticks out just a little too far and looks goofy, but it’s a minor nitpick that in no way effects how the sight actually functions. Sight seems to be well built for the cost
