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.

At $60, I was skeptical. Never had an at3 optic before so was unsure. I did not expect it to be this nice and well put together. It feels on par with a $150-200 optic. Easy to install, easy to zero, and holds zero perfectly on my plinker. Rubber cap is nice. Will definitely loose it though lol.

Tldr: Want a red dot that actually works without breaking the bank? Look no further than this at3 red dot here

I've had this RD50 on my Remington 870 12 ga. and it worked perfectly. Then put it on my Ruger Super Red Hawk .44 Mag. Working perfectly. It ended up on my Browning Buckmark [link removed] Field where it still lives today. Solid, tough, windage/elevation track perfectly, holds zero. Can't ask for much else. And to top it off, the folks at AT3 Tactical are the best!

I just threw the sight onto my AR9. Went to the range the next day and was on the paper 1st shot. Couple shots later I was done sighting it in. Definitely would buy it again.

Wasn't sure what to expect, contacted cust. Service prior to make sure that I wasn't, they assured me that it had been tested on heavier and could withstand the punishment.
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!

I have tried almost all of the under $100 Red dots, and this one stands out from the rest. I get them without a riser and piggyback them on my scopes. I have 4 with plans to purchase more
John McDonald Verified buyer
I purchased the RD-50 (FDE) but the windage/elevation adjustment knobs were not moving the dot at all and there was some red flare in the lower left. AT3 Tactical quickly sent me an exchange with a prepaid shipping package to send back the defective one. I mounted the new sight on a Winchester SXP Defender 20 Ga shotgun (laser printed picatinny rail/shell holder combo - Etsy). First thing I noticed was that there was no flare from the dot emitter. Next task was to get the red dot over the front bead sight and lowered downward a bit. Both windage and elevation knobs worked fine. The FDE color is a fairly close match to the shotgun's FDE. From all the positive reviews, I was pretty sure that the first one I got was just a fluke. I'm glad I took another go at it. Customer service was exceptional. I'm looking forward to zeroing and patterning my shotgun.

This is my second RD50, bought one several yrs back and still use it periodically and it's awesome, for the price and durability you can't beat it. I've also bought a couple higher end red dots since then and their great but your also spending a lot more money. I bought a new lever gun and needed some new glass. I've always enjoyed my first RD50, so bought another one to mount on it, great scope and easy on the pocket book.

For price and performance you will not find better. Love the smaller dot for longer shots. I've got em on 5 guns and I don't even look at others anymore
steve.henley Verified buyer
Purchased the RD-50 to mount on a Rossi R92 chambered in .357 magnum. First, it arrived a day earlier than expected; which is always appreciated. Mounting was easy as was sighting it in at the range. For such a reasonable price the RD-50 has a clear sight picture, good field of vision making for easy target acquisition, and a crisp dot. After 100 rounds, the mount remained firm and tight and the dot remained zeroed. Respective of the low price, one of the best red dots I've used.
