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.

Excellent Red Dot

I wish I had bought this red dot sooner. Form and function, it can run with my Trijicon all day and night.
The RD-50 by itself is very low profile without a riser, no problem though.
As can be seen the photo, the center of the RD-50 sits about 3/8" lower than the Trijicon.
I wanted another RDS but didn't want to fork over another $500.00, saw this and decided to give it a try.
Pros: Shipping was fast. I could track the package. Packaging was excellent. Mounting was quick and easy. Installing battery, no problems. This little red dot is well made. Didn't break the bank. Glass is clear. Dot easy to see. Brightness adjustment is acceptable.
Cons: None at the moment.
I recommend you guys quit dragging your feet and give this product a try before you go spending your kids inheritance money on something way more expensive.
I will be buying more of these.

Fits nicely at the front of my 300. Durable. Has all the adjustment would expect. Even the dot has a dimmer setting. Love it.

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

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.
