Features
- COMPATIBLE WITH 1911 STANDARD AND PICATINNY RAILS Includes a mounting plate for 1911 with Colt G.I Standard Rear Sight and a universal Picatinny adapter. To use, remove your rear sight, replace with this plate securely, and attach the optic for a firm, reliable connection every time.
- ENHANCE AIMING PRECISION WITH EVERY SHOT The RD3-009 delivers a sharp 5 MOA red dot with five illumination levels for quick target acquisition and steady aim. Mount the optic, power on, and center the dot for fast, accurate alignment during practice or defense.
- BUILT TO HANDLE RECOIL AND FIELD USE Constructed to endure heavy recoil, the durable reflex optic is shockproof, waterproof, and fog resistant. Simply sight in once, tighten the screws, and rely on its rugged build to maintain zero through every range session.
- EASY WINDAGE, ELEVATION, AND BRIGHTNESS ADJUSTMENTS Fine-tune your aim with tactile controls and five brightness settings to match any lighting. After installation, adjust windage and elevation until the red dot aligns naturally with your target for consistent accuracy.
- LONG-LASTING BATTERY WITH MOTION AWAKE TECHNOLOGY Powered by a CR2032 lithium battery (included) for extended operation. The Shake Awake feature conserves battery life by powering down when inactive and instantly reactivating upon movement. This advanced red dot optic ensures instant readiness, making it an excellent choice for tactical and sport shooting.

Very good quality. Packaged well. Delivered quickly. Unfortunately would not work on my Kimber. Ordered the ADE base for a different dovetail but still wouldn’t work on the Kimber. Very sad about that! Not the product’s fault!!! Added this set up to my Dad’s Sig Sauer instead and it works awesome!! Highly recommend this sight for a high quality budget red dot!!!

Its a little big, but it works. The screen reads clean with minimal splash in the dot.

Took a lot of filing to get the base to fit in the rear sight, put 40 rounds through and it flew off and hit me square in the nose, When it worked it works good for the price, need to make some modifications, longer screws and lock tight , then give it another try.

Was a little tight going on my Tisas 1911 but shaved a hair off and works great and looks great!

So I wish I could like this sight. The windage dial does not change anything at all. I have a laser on my pistol that is sighted correctly so I can turn it on and compare the change in windage/elevation relative to the laser. The elevation seems to work okay (at least it moves) even though I need a shim to cant it enough to be accurate, but the windage does nothing. I have tried multiple times & multiple ways to contact ADE Optics about this issue but cannot find any way to do so. Their phone number listed doesn’t work, the website on Amazon “contact info” doesn’t work, typing in their website won’t load, and I can’t find an email address for them. I would just return it, but I had to modify the dovetail that came with it to fit my Girsan 1911’s rear dovetail & it took me so long to get it on there correctly that I’m not taking it off. At least I got a baseplate out of this…. I guess. I just bought a vortex venom instead, since it uses the same base footprint. Since I’m keeping this sight I would like for it to function because I have other firearms I could mount it to, but alas, if I can’t get ahold of their customer service it will probably end up in the garbage.
