Compatible with a wide range of handgun mounts, this sight is perfect for professionals and enthusiasts seeking reliable, high-performance optics that keep you in the game longer.

## Description

The size of the red dot is about 30% longer than other red dots, the window is also bigger. Therefore, it will NOT fit some Optic Ready handgun model that will keep the rear sight to co-witness the red dot, such as Glock Mos. The size of this red dot does not sit in to the pre-cut. It only fits the mounting plate replace the rear sight on the top of slide(not in the pre-cut). It fit Doctor/Vortex Venom footprint /screw pattern. Model: RD3-015. Every time you turn on the dot it stays the same brightness level last time it was turned off. The lowest setting is invisible by human eye that is for using with a Night Vision. Come with a mounting plate for picatinny rail. Additional mounting plates for hunguns sells separately. Can also be used with a long range rifle scope for that perfect Backup System. Ade Advanced Optics first made its appearance in the firearms accessory industry by doing private label production for several major manufacturers and retailers. During this period, Ade Advanced Optics began receiving requests from numerous customers for access to the affordable, high quality products that Ade Advanced Optics was capable of producing. By soliciting feedback from both clients and end users, Ade Advanced Optics was able to overcome the challenges a new company often faces when entering a global market and industry, especially one as competitive as the shooting, hunting, and outdoors industry.

Review: Not what I expected, it just works. - I was not really expecting much when I ordered this item. It was going on a cheap gun that was going to just be used for fun. Well, this red dot optic surprised me with its sight picture and how bright it can get. I tested it out in full sunlight and I was able to find the dot without any issue. It stayed zeroed, once I adjusted it, without any issues. While it does not have some of the "cool" features on it like the more expenses red dots out there, it does the job I need it to do and it does it really well. Also, you don't have to remove it to replace the batter. So you can lock it down with thread lock and never have to worry about it coming loose. Overall I am very, very, happy with this.
Review: Great target aquisition! - Was a bit skeptical about ordering a lower end red dot for my XD9 Tactical based on fellow shooters advice. Was looking for an entry level red dot not knowing if I would even like shooting red dot. Compared to the other offerings, I decided this would be a great place to start. Easy to attach and profile is great. I like the larger screen as well as the brightness of the 4 MOA dot. Perfect for what I was looking for to experience red dot shooting. I used a laser bullet in my house to sight it in and then took it to the range. I was only about a half inch off at 30 feet and once I made the adjustment, was shooting 3 " groups consistently. I must say, that I am very impressed with the overall performance of this little gem. The only problem I had was with the windage adjustment being reversed. Took me a while to figure that it was reversed but once I realized it, I was able to easily zero in and lock it in place. I have only fired about 100 rounds at the range but it held true and I am now a fan of red dot shooting. Large screen allows easy target aquisition and I am looking forward to seeing how it holds up through competition shooting.

### ⭐⭐ Doesn't Fit My Glock
*by A***R on January 23, 2020*

I am unable to determine the accuracy of this red dot because it could not be installed on my Glock 17 Gen4 MOS. All of the YouTube videos from ADE indicated that this red dot would fit a variety of firearms including Glock. Additionally, the size of the red dot was extremely small … much more so than anticipated … and it was difficult to see clearly. Returning it, and beginning another search for something that WILL fit my Glock. Other than these issues cited above, if it truly will fit YOUR firearm, the unit itself seemed to be very sturdy with a very large viewing area.
