Rugged and Reliable, New and Improved.  Premium Features and Outstanding Value.

The best value in red dot sights just got even better. Optimized for the AR-15, the AT3 RD-50 PRO pairs the tried-and-true RD-50 red dot sight with a new lightweight cantilever riser mount.

Precise

  • The New PRO-MOUNT Cantilever Mini Riser mounts secure to your AR, ensuring you get on target faster, and stay on target no matter what.
  • Multi-coated lenses are scratch-resistant and provide excellent image clarity
  • Crisp 2 MOA red dot allows for accurate, both-eyes-open shooting.
  • Parallax free design: The red dot stays on target, no matter where the shooter’s eye is
  • 11 red dot brightness settings provide optimal visibility in any lighting conditions

 

Tough As Nails

  • Matte black anodized finish resists scratches and scuffs while you’re moving in the field.
  • Rubber gaskets on the turrets and battery cover keep the red dot completely waterproof.
  • Nitrogen purging ensures the 6061 T6 aluminum body resists fogging and moisture.
  • Shockproof circuitry resists damage, even when the dot takes a beating.
The RD-50 Pro is also available in Flat Dark Earth options to match custom AR-15 builds.

Incredible Value

  • No other Red Dot has a Riser and Cover at this price.  This is the Best Red Dot Under $100!
  • The RD-50 PRO is factory-direct – no markup from distributors.
  • Up to 50,000 hours of battery life at the lowest setting
  • CR2032 Lithium battery included.

Frequently Asked Questions

Q: How do I know which riser mount to get?
A: For AR’s, we generally recommend the .83″ mount if you are running without iron sights since it puts the red dot at the standard height of mil-spec iron sights. If you’re using this with iron sights, we recommend the 1″ mount for “lower 1/3 cowitness”. (See below graphic for an explanation of cowitness types)

Difference Between Absolute vs. Lower 1/3 Cowitness

The .83″ mount is the most popular option, but many people prefer the 1″ mount as it allows more versatility when combined with iron sights.

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.

Happy with this one

I purchased the RD-50 (FDE) but the windage/elevation adjustment **** 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 **** 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.

Really Like

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.

Thank you for your positive feedback! We are glad to hear that you are satisfied with our AT3 RD-50™ Micro Red Dot Reflex Sight. We take pride in providing high-quality and durable products at an affordable price. We hope you continue to enjoy your RD50 and thank you for choosing us for your scope needs. Happy shooting!

S&W Model 41 RD-50 Addition

Added the AT3 RD-50 Micro Red Dot to my newly acquired S&W Model 41 and so far am quite happy with the sight (only one outing to date). I can remove and replace the sight from the pistol and it repeats without having to adjust the sight. Nice product!

Thank you for taking the time to leave a review! We are thrilled to hear that you are enjoying your AT3 RD-50 Micro Red Dot on your S&W Model 41. It's great to know that the sight is repeating without needing readjustment. We hope you continue to have a positive experience with our product. Happy shooting!

Great red dot

Just picked this bad boy up, can’t wait to use it! First thoughts, things well built and the customer service is outstanding.

Most definitely want to read the directions and required specs to mount (20 inch pounds)

I sheared off the bolt by over-tightening by hand cause I’m a meat stick but customer service was fast to send me a replacement

All in all, I’m extremely happy with it and would purchase again for sure

Thank you for your review! We are thrilled to hear that you are enjoying our AT3 RD-50 Micro Red Dot Reflex Sight. We always strive for excellent customer service and are happy to hear that we were able to quickly assist you with a replacement bolt. Thank you for choosing our product and we look forward to serving you again in the future. Happy shooting!
