            Frequently Asked Questions

            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.

              Great Red Dot At A Great Price

              Great optic. Great price. Great customer service.

              Thanks for sharing your experience, Kevin. We're glad you're satisfied with your purchase- AB

              With the riser, works great on low profile iron sights, i.e. M1 30, Mini 14/30, etc. when using scout rail, see pic.

              Looking good! Thanks for sharing your feedback, Jeff. We're glad you're satisfied with your purchase. - AB
              Nice Scope

              Arrived on time. It was easy to mount. I have not sighted it in yet but it seems easy enough. Scope really feels sturdy. I like the different settings on the scope. I like it so far.

              Thanks for sharing your experience, David. We're glad you're satisfied with your purchase. - AB
              Great Optic!

              I purchased this optic based on the features and price. I sighted it in yesterday and so far I could not be more pleased. Mounted on my Smith & Wesson M&P 15 it puts 5 shots in less than a quarter at 25 yards and from a rest in less that 5" at 100 yards...that is more than adequate for my needs.

              Looking good! Thanks for sharing your experience, Scott. We work hard to meet expectations like yours, we're glad we hit the mark for you. Cheers! - AB

              Thanks for sharing your experience, Dario. We're glad you're satisfied with your order. - AB
