Survived a full training class - ADE Advanced Optics RD3-006x 1x Reflex Green Dot Sight w/D1 Rear Optic Mount Plate

I bought this optic specifically for a two-day defensive handgun course. The pistol was dropped in gravel, exposed to dust, and fired extensively throughout the weekend.

The RD3-006B performed flawlessly. The dot never flickered, the mounting screws stayed tight, and zero remained unchanged. After the class I cleaned the pistol and inspected the optic expecting to find some wear, but it still looked great.

I've since used it in several local matches and numerous practice sessions. It continues to perform beyond my expectations. For shooters looking for a dependable green dot without spending a fortune, this optic deserves consideration.
