Model RD3-012 + HM23(SAR CM9 Plate)
This combo includes an ADE Delta RD3-012 red dot sight, a mounting plate for the SAR USA CM9 pistol, and a standard picatinny mount. The included plate is only compatible with the CM9 model and does not fit other SAR models such as SAR 9, ST9, or K2.
The new ADE Delta (RD3-012) features a Motion Activated System. When turned on, the red dot illumination enters sleep mode after five minutes of inactivity but instantly reactivates to the previous brightness setting upon detecting motion or vibration.
Powered by a single CR1632 battery. Press and hold the DOWN switch for 3 seconds to turn the power on/off, and the UP switch for 3 seconds to change the reticle. Quick press the UP/DOWN switches to adjust brightness levels. Can also be used with a long range rifle scope for that perfect backup system. The lowest setting is invisible by human eye that is for using with a night vision.
6 MOA dot. Come with Protected Cover, Adjustment wrench, Adjustment dialing plate, User Manual and Picatinny mounting plate. Additional mounting plates for a specific pistol is not included.
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.

Good optic but takes practice to use
The optic itself works well and the mounting plate fits my CM9 exactly as described. My only challenge was getting used to presenting the pistol in a way that consistently brings the dot into view. That’s more of a training issue than a problem with the optic, but it took some practice before it felt natural. Once I got used to it, the sight performed reliably.

Performs above expectations
Considering the price, this red dot performs extremely well. The motion activation, bright dot, and included mounting plate make it a very complete package. It’s a great option if you want to try a pistol red dot without spending several hundred dollars.
-
Quick to zero
Zeroing the optic was quick and simple thanks to the adjustment screws and included tools. Once dialed in, the sight stayed perfectly aligned. The mounting plate fits the CM9 securely and keeps the optic stable during shooting.
-
Excellent visibility
The sight window is large enough to make finding the dot very easy. The dot itself is bright and remains visible even in strong daylight conditions. I’ve used it on several range trips and the optic has performed consistently every time.
-
Works on multiple setups
One thing I like about this package is that it includes a Picatinny mount as well. That means I can move the optic between my pistol and another firearm if I want to experiment with different setups. The optic itself performs well and the shake-awake feature is very convenient.

Great optic for beginners
This was my first pistol red dot and I’m very happy with it. The installation process was simple and the mounting plate made it easy to attach the optic to my CM9 without any gunsmith work. The dot is bright and easy to track during rapid fire drills. Overall it’s a great entry-level optic.
-
Holds zero very well
After installing this red dot on my CM9 I took it to the range for several practice sessions. Once I zeroed it, the sight stayed perfectly aligned even after multiple magazines of shooting. The controls are simple and easy to use and the motion activation works reliably.
-
Makes target acquisition much faster
Adding this optic to my CM9 has significantly improved my target acquisition speed. The dot appears quickly in the window and allows me to stay focused on the target rather than aligning iron sights. The mounting plate fits the pistol exactly as advertised and the optic stayed zeroed after several hundred rounds.
-
Excellent clarity and solid build
I was pleasantly surprised by the overall build quality of this red dot. The aluminum housing feels sturdy and the lens clarity is better than I expected for an optic in this price range. The dot is crisp and easy to see, and the brightness settings allow good visibility in different lighting conditions. It’s been very reliable during range practice.
-
Always ready when needed
The motion activated feature on this optic is probably my favorite part. I don’t have to remember to turn the sight on every time I take the pistol out. The dot wakes up instantly when the firearm moves and shuts off after sitting still for a while. That helps save battery life and makes the optic very convenient to use. The mounting plate also fits the CM9 perfectly.
-
Everything you need in one kit
This combo package is a great value because it includes the red dot, the mounting plate for the CM9, and even a Picatinny mount if you want to use it on another platform. Installation took less than ten minutes and everything lined up perfectly. The optic window is clear and the dot is easy to pick up quickly during target transitions. After several range sessions the optic has held zero without any problems.

Perfect optic setup for my CM9
I purchased the RD3-012 Delta with the HM23 mounting plate specifically for my SAR USA CM9, and the setup turned out to be exactly what I was hoping for. The mounting plate fit the pistol perfectly and replacing the rear sight mount was very straightforward. Once installed, the optic felt solid and secure with no movement at all. The 6-MOA dot is bright and easy to see even on sunny days at the range, and the shake-awake system works exactly as advertised. When the pistol sits still the dot goes into sleep mode, but as soon as I pick it up the dot instantly turns back on at the same brightness setting.
