    Fits Canik TP9 sfx

    Posted by Dom on 4th 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.

    5.0 out of 5 stars Buy This First Before You Spend a LOT of $$$

    Posted by YOUNG C. on 4th 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!

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

    Posted by JIMBO on 4th 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 4th 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

    5.0 out of 5 stars Very Impressed

    Posted by Customer on 4th Aug 2025

    I was a bit skeptical when buying the item but for the cost I thought I'd give it a try. I took it to the range and fired over 500 rounds from my Glock 17. After zeroing the weapon, the optic maintained its "Zero" the entire without any lag in performance. I normally fire Sig Sauer sight on my pistol but this is right up there. I was able to place rounds within a 1-inch group at 20 yards away. I recommend this sight to anyone looking to try out red dot pistol optics. The one complaint I had was that there are no instructions for zeroing. I had to go on YouTube for a tutorial which was a little frustraiting.

    It stays on target for the long hall!

    Posted by HANKERVIN on 4th Aug 2025

    I put it on a Canik TP9 combat elite. I'm just breaking in the Canik and my old eyes couldn't do better than 4'' groups at 25yds. After putting on the ADE reflex sight I was shooting 2'' groups at 25yds while sighting it in. After 5 three shot groups I had it within 1/2'' high and 1'' right. I know this because the next 15 shots were amazing. I aimed 1'' to the left and emptied the magazine! 12 shots hit in 1''group 1/2'' high and dead center, the other three within 2''. I've never done that before, 15 shots! TWO INCH GROUP, 25YRDS. I know its only the first day, I will post another review in a couple months after I put at lest a thousand rds. through my Canik TP9 combat elite/ ADE/Tactical Reflex Dot Sight.

    Unbeatable for the price

    Posted by kyle bellah on 4th Aug 2025

    Shipped quickly and installed very easily on my 9mm cz clone. Dead on right out the box at 30 yards with a lazer boresight, and after almost 500 rounds still keeping 2.5" groupings. The only downside was the alignment pin holes on the rear of the sight didnt fit the mount i purchased (fronts fit perfect) other than that its been perfect. ive been comparing it to the Vortex and fastfire that my buddies shoot and other than this sight not having an auto-off feature, i think i got the better deal. Definitely buying a second and third for my other two firearms *edit* Now almost 1500 rounds downrange with the optic and it's still holding true. Swapped it to a friends AR15 with the included rail mount(which I did not need on my pistol) and the sight was 1" low at 100 without ever being adjusted.

    works very good and cost 3 to 4 times less than the big name red dots

    Posted by mike chris on 4th Aug 2025

    this is the ade rd3-012 red dot sight. I am using it on a 12 gauge shot gun. I installed a rail on the gun to mount the red dot on, mount comes already on the red dot. It sighted in easily and precise. I have to wear glasses to see up close, out to about 4 ft. but for some reason that i don't know i see this red dot perfect and sharp without the glasses. I don't know if it will be that way for anybody else but for me it was amazing. I've shot slugs, buckshot and number 4 rabbit loads so far [ 36 rounds total ] and the sight has handled it. I don't know how long a battery will last yet but you have to remember to turn it off when your done it does not shut it's self off. I can't say if it will hold up long term but it looks well made and is aluminum not plastic and i am going to buy another one for my lever action 3030.
