Introducing ADE’s New Flat Dark Earth (FDE) Green Dot Optic Series
ADE now offers a stylish Flat Dark Earth (FDE) color option for some of its most popular green dot and red dot sights. The FDE shade is an earthy, tan color designed to blend aesthetically with a wide variety of firearms. While ADE’s FDE may not be an exact match to every handgun manufacturer’s proprietary FDE finish, it provides an appealing complementary tone for coordinated firearm setups.
Key Features of the ADE Green Dot Sight
-
Comes with a Picatinny mounting base and is compatible with multiple handgun mounting plates that replace the rear sight dovetail.
-
Designed to fit Doctor Footprint plates/slides seamlessly.

3 MOA dot size with 5 brightness/illumination settings.
-
Fully windage and elevation adjustable, with lockable turrets for maintaining zero.
-
Unlimited eye relief for fast target acquisition.
-
Powered by an included lithium CR2032 battery.

Since its initial 2014 release, numerous enhancements have improved durability, recoil resistance, and zero retention.
-
Recent hardware updates include a redesigned front switch, battery housing, and mounting components.
-
Proudly designed in Oregon.
Installation Recommendations
-
While installation can be performed without a gunsmith, professional installation is highly recommended.
-
Improper installation (e.g., incorrect torque) can cause loose screws, loss of zero, damage to firearm or optic, or personal injury.
Astigmatism Notice
-
If the green dot appears distorted (splash, half-moon, starburst shapes) instead of a clean round dot, you may have undiagnosed astigmatism.
-
To verify, take a photo of the dot with your cellphone. If the photo shows a perfectly round dot, this confirms astigmatism.

ADE RED DOT
I have this mounted on my 1911 sig 10mm. It zeroed fast and keeps its zero through out. I have put about 50 rounds and haven’t had any issues with the optic.

RD3-006B1-S Green Dot Mini
Fit perfectly on my FN 509 Tactical, and the matching FDE looks great, very durable and very accurate, all with a price that absolutely CANNOT be beat!

ADE RD3-006B1-S
Nice little optic, you really can't beat it for the money. It absolutely is not FDE though, it's burnt bronze. OPTICS FACTORY is straight up, I wouldn't hesitate to buy from them again.
