This green dot sight comes equipped with a Picatinny mounting base and is also compatible with various handgun mounting plates that replace the rear sight dovetail. It's designed to fit the Doctor Footprint Plate/Slide seamlessly.
The on/off switch for this sight is conveniently positioned at the front, making it much easier to press compared to red dots with side-mounted switches. It features a 3 MOA dot size and offers 5 illumination settings. The sight is fully adjustable for windage and elevation and can be locked into place. With unlimited eye relief and various illumination settings, it is powered by an included lithium CR2032 battery.
Since its initial release in 2014, we've implemented numerous improvements to enhance its durability, ensuring it can withstand recoil while also improving its ability to hold zero. The front switch, battery housing, and hardware have all been recently updated, reflecting our commitment to continuous enhancement. This product is proudly designed in Oregon.
Although it's feasible to install the optic on a handgun without the assistance of a gunsmith, we highly recommend seeking the expertise of a professional for the installation process. It's essential to note that unprofessional installations, such as improper torque application, can lead to issues like loose screws, an inability to hold zero, damage to the firearm or optic, and even pose a risk of personal injury.
If you're not seeing a perfect round dot but instead observe a splashed dot, half-moon shape, multi-dot, or starburst, there's a high probability (99%) that you might have astigmatism without being aware of it. What you perceive is likely a small reflection of the LED light on the lens. A quick and simple way to confirm this is by using your cellphone to take a photo of the dot. If the photo shows a circular dot, you've essentially diagnosed yourself with astigmatism.

Don’t look anymore for a great pistol reflex site. This is it.
Fantastic reflex “green” dot site for a pistol. I put this one my Ruger Mark IV Lite, got it sited in and I’m shooting 2” groups at 25 yards. And that’s just the first 50 Rounds! It will only get better. The value is fantastic and super easy to adjust.

Great sight for the money.
Great sight for the money. I didn’t know if I was going to like a RDS on my Glock 34 so I didn’t want to spend a lot. Glad I went this route. The sight is great, holds zero, and easy to use. My only issue is that will have to remove the sight to replace the battery. Wish there was a cap on top to replace it. That’s my only issue with it.

Great sight at a great price
Very nice sight for the money. Mounted it on my RIA 1911. Not bad. Replacing the dove tail sight adapter was a pain to remove. I suggest a sight tool as it took some TY orque to get off the old sight and put the adapter on as it is very snug. Other than that the sight works awesome!!!

Save 150.00 dollars and give it a try.
This unit mounted as it should. Was easy to zero in and I am astonished at the accuracy. With the cost of ammo I have only shot 50+- rounds and it has held zero. Brightness in full 2pm sun no shade in more than great on the 3rd & 4th settings.

I love this product
I am really impressed with the red dot sight, it holds a zero and the brightness is really really good. What I love most is that I receive one that was damage and before I can send The other one back they were already sending me a new one which I have now.

Way to easy to install
Perfect fit, don’t over tighten the screws and use thread lock

Can't be beat for the price
I looked at a lot of optics for my Taurus TX22 and for the cost of the RD3 you would be hard pressed to find a better deal. Easy to mount, easy to sight in and real easy to see even in bright light. I'm so happy with this optic I will be trying one on my EDC 9mm.

Great sight for the money
You aren't going to get any better than this sub $65. The sight is nice and bright, even during the day. Easy enough to adjust and dial in the accuracy. I mounted mine on an M17 (with rail adapter). It makes a great pistol sight. Fairly low profile and easy to shoot with both eyes open. Remember to loosen the locking screws before making any adjustments to the sights or you could damage the optics.

Great little green dot
It’s a good looking optic. I put it on a Ruger mark iv lite. It looks fantastic, I wish the green light was a bit brighter but it’s honestly not horrible. Still able to see clearly in broad daylight. It’s easy to adjust and easy to zero in. It has held its zero perfectly throughout 100 rounds so far! Can’t wait to shoot it more. Makes my gun look that much better.

A nice entry point into pistol mounted optics
I purchased this optic based on the fact that ADE has a mounting plate for SR series Rugers and they are very reasonably priced. The reviews seemed worthy of purchase and I wanted to try my hand at some modest gun smithing and optical sights on handguns. The sight is very well built and finished. The overall look of the sight is something you would assume costs several times your investment. I am looking forward to taking this to the range to see how it withstands use.
