As a firearm enthusiast, I can confidently say that the ADE RD3-006x Green Dot with Rear Sight Optic Mounting Plate is a stellar addition for anyone looking to enhance their shooting experience, particularly for Glock, Canik, and Taurus pistol owners. This product is designed with an understanding of the diverse needs of shooters, and I believe it stands out for several compelling reasons.

One of the most notable features of the ADE RD3-006x is its compatibility with a wide range of pistols, specifically all Non-MOS Glock models from the Glock 17 to Glock 43 and even the “100”. This versatility means that if you own a Glock, you can easily upgrade your sighting system without the hassle of purchasing additional accessories or modifications.
