Ade Advanced OpticsRD3-012-G Green Dot Micro Mini Reflex Sight for Glock MOS 17 19 34 35 40 41 Pistol

I bought this sight for my Glock build just played around with it a little so instead I put it on my rifle which holds up to the recoil just fine. For the price perfect.

So far, so good ! Mounted this on a Glock 21 45ACP suppressed. Sight-in was a breeze since it was just 3 inches low at 25 yards. Followed instructions to unlock the reticle first, made a few turns, and all done. I utilized the matching Ade sight base. There were additional screws supplied with the sight which was fortunate since the screws pre-installed on the base were too short for a solid install. I used the next size up screws with everything torqued to 12 inch lbs and so far it's holding up. I appreciate the access to the battery without removing the sight. I'll need to put a lot more rounds through it as I only fired 25 today. The 6 moa dot is fine for the 45 ACP. It also seems to allow me to use lower brightness settings and avoid "starbursting" due to my astigmatism. Shot it in full sunlight today and had no trouble picking up the dot. We'll see how it holds zero over time, but I'm very happy with it's performance so far. There are plenty of other red dot choices out there with many more features, but those are 2 to 4 times the cost. Right now I couldn't be happier with my very modest investment in this sight.

Took me a few tries to figure out which plate (included) to use to mount on the Glock 19 (Gen5 MOS), but that's due to my inexperience. Once resolved, mounted easily and worked perfectly. Also mounted it on the rail on CAA MCK (Micro Conversion Kit) for the Glock 19 and worked perfectly. Very happy with this sight.

I admit I should have been more careful about the sizing and I should have checked the dimensions. It's ridiculous that there are different dimensions of cutouts. I had to order it months in advance of when I actually was able to sit down and try to install it. My exchange warranty window has closed so I am going to try to put it into a clamp and file it down to fit. It is only maybe 1-2 millimeters too long. Not sure which side is too long I need to buy some caliper to do some measurements.

So I purchased this for my G2c and it went on with no issues. There was only two items that made me not give it 5 stars 1st is the provided screwdriver tool. It was defective the little screw driver side just spins in the handle. Not a problem when into my back of random collected tools and found a micro screw driver that did the job. The 2nd issue is cosmetic its too wide its too wide it hangs over an 8th of an inch on each side. So does it do what it suppose to? Yes. Will it hold up to my gut and edc usage of going in and out of vehicles being pressed on day to day we will see. If you don't see an update then it is working like a charm

Mounts in very solid. Dot is super visible. Does not interfere with my iwb holster.

This is a love and hate relationship between me and this optic. I love the shape, and the quality, but its just not all there. You get what you pay for I guess.

You will be surprised and happy and will buy another one. I have three different models. Like them all and saved a butt load of money.
