ADE RD3-006x Green Dot + Rear Sight Optic Mounting Plate/Adapter for All Glock (Non-MOS, Non-Aftermarket Slide) Standard Models,Canik TP9SF,Taurus GX4,TX22 GEN2,G3C,G3 with Factory Steel Sights Pistol

This is a great optic for the money, I would definitely buy this again for a different gun. This optic is better for me than my Vortex Venom on my CZ 97b. The ADE green dot is extremely visible, the on/off button is in the center of the optic, above the barrel, not on the side above the slide serrations like the Vortex Venom. This means it’s really unlikely you’ll turn it on or off unintentionally, no matter how you carry it. This came zeroed perfectly, I matched it with a 9mm bore laser and I didn’t have to touch the elevation or windage screws.I have one minor caveat with this ADE green dot, but it’s tiny and I still give this 5/5 stars. I bought this to stick on my Glock 43x (non-MOS) it comes with a metal baseplate which screws into a mounting insert which sits under that, replacing the rear sight. My only issue is the metal insert which goes into the sight slot was far too large to fit without sanding it. The rear sight can be removed with a sight pusher, but the mounting insert is too low profile to install with the pusher (because the base plate has to screw into it from above and sit flat). So I had to install the insert with hammer and punch, but it was too large for the slot. It went about 25% of the way in and got stuck completely, I had to hammer it back out the opposite way.The insert is kind of triangle shaped with a flat top, I had to sand it on the 2 top two diagonal faces until it was bare metal. I just laid a piece of medium grit sand paper down and rubbed it manually, took like two minutes. You do have to be careful that you don’t take too much off or the base plate with optic will slide out. I had sandpaper, it took a couple of minutes, it fits perfect now, no big deal.So what does the Vortex Venom have for $220 that this doesn’t at $68.99? Not a lot to me. The Vortex and the ADE optic both have adjustable dot brightness settings. The battery cover of the Vortex Venom is on top of the optic, which is the only superior design element it has over the ADE optic. On the ADE you have to use an allen key on two screw which connect to the base plate, and remove the whole optic in order to access the battery (you dont have to remove the base plate or the sight insert.) To me this isn’t a deal breaker, dot optics use so little power and it’s really easy to take the 2 screws out of the base plate. Only other difference between the Vortex Venom and the ADE I’m aware of is the on off button. On the Venom the button is on the side where it can too easily be hit by accident. It’s still easily accessible on the ADE (front face, above barrel) but way less easy to hit by accident.Overall, I give this optic a 5/5 for my needs. The ADE has everything I need, and is literally 1/3rd the price of a Venom. A minor amount of sanding isn’t a big deal for me personally so it’s a nonissue.

Bought just as a temporary sight but haven’t changed it yet (2months) very clean and slick design easy to install bright has 5 modes and all are bright worth the price

Install was easy enough on my Glock 19. Made sure I have the locktite blue to keep it snug and tight. But first trip to the range, I noticed it cracked on the upper left corner after maybe 7 shots. Returned it for a refund. My friends told me ADE is a good first red dot...I don't think so and now I am kind of avoiding all red dots.

Reticle moves after being shot once

Accurate and strong red dot. The only problem is that you have to push a button to turn it on

Haven't gone out to shoot yet, but glass is clear, construction is really sturdy, everything is really nice I honestly cant believe it was so cheap. I wish it stayed on until I turned it off, but other than that it's great. For those of you trying to research it, the packaging that came with it says it's a 6 moa dot, just fair warning. Not sure which is accurate the ad or the paper work. When you turn the dot off, or when it auto shuts off, it comes back on to the same brightness setting you left it at. One button makes it easy to know what's going on, but an up and down would sort of be nice. Glock rear sight mount went in nice and tight, and looks great. No issues at all. All in all, you cant beat it for the price. EDIT - After using it and shooting, its still holding up great. I will be buying another for my rifle and I have suggested it to numerous people.

It mounted onto my Glock 22, so that’s all matters to me. Have not tried it out yet.

Install was smooth, everything seemingly fit as it should. Happy with the brightness of the green dot and visibility.However, one major issue I’m having.. zero’d in with bore laser, after about 100 rounds I noticed my aim seemed off. Checked with laser and the green dot shifted significantly. Made the appropriate adjustments and it did it again.. This happened a few more times after going to the range off and on over the last year or 2 and I’ve finally figured I can’t rely on this. All screws have been removed and reinstalled with lock tight to ensure it wasn’t a loose screw and the same problem kept happening.After removing I can see damage to the slide where the baseplate is shifting.I wish I had an optic ready slide instead of the rear sight adapter. I gave it a try, just going with night sights moving forward instead of retrofitting
