            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.

              Good Quality

              Nice, light weight little red dot. I will say the protective caps could be a little better quality. They don't stay on or get a tight fit like my Romeo 5 caps. Good scope though. Just one ding on the caps. Turret is very stiff as it should be so it doesn't move around if it gets bumped or shift during firing.

              Thanks for sharing your experience, Paul. Your suggestion about the cap is noted. We'll continue working hard - AB
              Works fine

              Seems to be well built and is very comfortable to use on a flat top AR15. I was impressed with the lifetime warranty and the size and brightness of the dot.

              Thanks for spreading a good word for AT3, Richard. We're glad you're satisfied with your purchase.
              Works great

              Purchased with 1 inch riser. Mounted easily on a 870 Magpul. Works well. Still need to sight in. ‘RD-ARMOR’ a bit loose. May switch back to ‘bikini style’ lens cover.

              Thanks for sharing your experience, Rusty. We're glad you're satisfied with your purchase - AB
              Nice fit RD 50 with impressive results.

              I read some reviews on the RD 50 and was looking for something to get a lot of bang for my buck so to speak. I purchased the RD 50 pro with riser at the price of 99.99 and have to say I am very Impressed. Mounted on 223/AR , zeroed in in just a few shots and have put SEVERAL rounds through it since and it is holding right on spot, adjustments were very solid along with red dot very clear this is such an awesome deal. Shipping was very quick, will be adding more AT3 products to my use.

              Thanks for sharing your experience, Charles! We work hard to meet expectations like yours, we're glad we hit the mark for you. Cheers! - AB
              First Red Dot

              Fantastic piece of equipment, although I can't say the same for the red dot. The red dot isn't a dot at all, it's more like a distorted/ unsymmetrical dot.

              We appreciate your feedback, Nathan. Most cases when we hear of issues where the dot isn't perfectly round, or has a 'starburst' effect it's due to astigmatism. If you feel it's really the red dot, please send us an email at support@at3tactical.com so we can facilitate a return. - AB
