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.

AT3 RD-50

Mounted the AT3 RD-50 on a Zastava AK varant. It holds zero very well but the red dot is very hard to see in bright daylight. I had the red dot selected to the highest setting. It is impossible to see in snow-covered terrain with the sun fully out. Sight has been in rain and freezing cold snow. It's a solid built sight. Maybe the green dot is easier to see. **( I shot close to 900 rds with sight on my rifle)**

Can’t zero it in

Well I’m not to sure if I’m doing it wrong but when using a bore sight I can not zero the red dot in with the bore sight laser it does not go low enough to be directly on the laser so it’s maybe half an inch above the bore laser but other than that I love it

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

AT3™ RD-50 PRO™ Micro Red Dot w/ Riser Mount

This is my 5th one. Only 4 of them are in operation. Had a lens crack on one when a spent shell casing hit it. (nothing to with craftsmanship of the product, just freak thing that happen) Have 3 mounted on rifles and one on PCC. Easy to sight in and holds up very well to recoil.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

Can't beat the price

For my budget build, I needed an inexpensive red dot, this AT3 Red Dot fits the bill. The dot isn't too large when it's activated and with the different level of brightness, it works. Zero complaints. Zero issues.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

10/10 Red Dot Thanks AT3!

So far so good!
It’s durable, fits great and is easy to install. Super easy to adjust as well, and the multiple brightness settings are really helpful for some outdoor fun. The only thing I would change is for the sight to be more centered. As it stands, my sights are set towards the bottom end of the glass. Certainly not ruling out shoulder placement on my part though.
New AR+new red dot=
New adjustments lol.

In fairness, the only reason it’s an issue is because I’ve
also ordered the AT3 3x magnifier RRDM scope. The scope itself is a cool piece of equipment-but it’s tough getting the red dot flush for a quick long range shot. Scope sits just a ‘bit’ higher than the red dot, and is not quite as sturdy a fit.
That being said-I’m reasonably new to red dots, and AR life in general. So…AT3 if you have any advice/suggestions send them my way! Always eager to learn and improve.
Regardless-super happy with my purchase and highly recommend it to any who take the time to real this novel.
Easy to install, easy to adjust, affordable, durable and looks badass (for those bonus points that don’t really matter) 😂.
10/10 recommend thanks AT3!
Ps-sorry for the terrible picture. My wife was yelling at me to stop playing with my AT3 gear 😂.
