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.

Excellent product

RD-50 works great. 40 yards last three shots sighting in..... Ruger 10-22 take down. Contacted another company that has a similar looking red dot and asked about their warranty. One year only because it has a battery and lifetime on their scopes easy choice at3 tactical rd-50. This is my second one and will buy more for gifts. Thanks for such a good product and standing by your word.

Thanks for sharing your feedback, Ronald. We're glad you're satisfied with your purchase. Cheers!
Great sight at a great price

I got a really good deal on this sight because it was an open box return. I also had a coupon so I only paid $53.99 for it and shipping was free.
The description of the sight said because it was an open box return it might have blemishes and/or scratches but would be in perfect working order.
Well not only does it work just fine, but I don't see a blemish or scratch on mine. It looks brand new.
I just needed to attach it to a 1" cowitness riser because I have BUIS. I popped the included battery in it and had it zeroed in a few minutes. It's very easy to adjust via windage and elevation nobs. The nobs seem to have very tight tolerances, for exact adjustments. This sight amazes me for it's quality, even at the regular price of $74.99. I have friends that have paid a lot more for the same or less quality sights.
I also had a question about the sight and the response was very fast, excellent customer service.
I highly recommend this company and this product. Thanks AT3!

Thanks for sharing your feedback, E.R. We're glad you're satisfied with your purchase. Cheers!
