          Frequently Asked Questions

          Q: How do I know which riser mount to get?
          A: For AR's, we generally recommend the .83" mount, since it puts the red dot at basically the exact same height of Mil-spec iron sights. That means if you have a front sight, the red dot will be just at the point of the sight post. This is called "absolute cowitness" 

          Either of these mounts will work, it's really personal preference. For most people, the .83" mount seems to be the right choice, and it's the most popular. If you would like, you can get the 1" mount and it will sit a little higher than the iron sights. Now, if you have a front sight, it would appear in the lower 1/3 of the red dot sight's window. That is called "lower 1/3 cowitness" 

          Q: Do I need to use iron sights along with 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.

          Q: How are your prices so low?
          A: Since we sell AT3 products directly to the customer, vs selling through a distributor, we are able to pass savings on to you.
