Frequently Asked Questions
Q: Do I need to use iron sights along with the RD-50 Red Dot Sight?
A: NO – Iron sights are not required to use this red dot sight! The red dot sight can be used on its own. Many people choose to use iron sights as a backup, but they are optional. This red dot sight will work great on “optics ready” rifles that don’t have any iron sights.

Our goal is to provide high-quality products that make shooting easier and more enjoyable. We hope you continue to enjoy using it and we appreciate your support. Happy shooting!
I've only put about 25 240gr rounds down range with it installed and zeroed and it's good. The brightness control (11 settings) is really good, although a bit tight, but I'm sure that will loosen a bit over time. No noticeable distortion near the edges and the glass is clear.
Couldn't really ask for more especially with the warranty. I will be getting a few more for other platforms.
Great job AT3!
