4. ADE RD3-006x Green Dot + Rear Sight Optic Mounting Plate/Adapter for All Glock (Non-MOS, Non-Aftermarket Slide) Standard Models, Canik TP9SF and Taurus GX4, G3C & G3 with Factory Steel Sights Pistol

As someone who is always on the lookout for reliable and efficient accessories for my firearms, I find the ADE RD3-006x Green Dot + Rear Sight Optic Mounting Plate/Adapter to be an impressive choice. This product is specifically designed for Glock models (Non-MOS and Non-Aftermarket slides), as well as the Canik TP9SF and Taurus GX4, G3C, and G3 with factory steel sights. The versatility it offers for various pistols makes it an attractive option for anyone who owns more than one of these models. If you’re looking to enhance your shooting experience, this is definitely a product that deserves your attention.

One of the standout features of this package is the included ADE red dot sight, which is complemented by a pre-assembled picatinny mounting plate and a Glock mounting plate that replaces the factory rear sight dovetail. The ease of installation is a significant advantage here, as it allows users to set up their optics quickly without needing extensive gunsmithing. However, while it’s possible to install the mount without professional help, I would still recommend consulting a gunsmith to ensure everything is set up perfectly. This extra step can make a difference in performance and reliability.

The ADE RD3-006 has been enhanced with several improvements that are sure to elevate the user experience. For instance, the new self-locking mechanism replaces the traditional rear locking screws, making it easier to use while also ensuring a more secure fit. Furthermore, the motion-activated technology is a game changer.

This feature not only prolongs battery life but also ensures that I’m always ready when it’s time to take my shot.

In terms of durability, the ADE RD3-006 is shock and fog proof, and while it is rain resistant, it’s important to remember that it isn’t waterproof. This is still a great advantage for outdoor enthusiasts like me who might encounter various weather conditions. The precision ground and polished lenses promise a clear and crisp sight picture, which is essential for accurate shooting. The 4 MOA dot size, along with five illumination settings powered by a CR2032 battery (included), provides flexibility depending on lighting conditions and personal preference.

One thing to keep in mind is that some users may experience issues with dot clarity due to astigmatism. If you notice a splashed or distorted dot, it might be worth checking for astigmatism, as this can affect your shooting experience. Some users with this condition find that they can adapt to the imperfect dot or prefer a larger MOA red dot. If you fall into this category, it may be beneficial to explore your options based on your individual needs.

Overall, the ADE RD3-006x Green Dot + Rear Sight Optic Mounting Plate/Adapter stands out as a high-quality product designed for serious firearm users. With its user-friendly design, enhanced features, and compatibility with multiple popular pistol models, it is an excellent investment for anyone looking to improve their shooting accuracy and experience.
