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.

The most optics for the money

I recently purchased three AT3 red dots. i have since mouhted two. one on a Ruger blackhawk, 357 mag and one on my 3-gun AR as a 45 degree angke back up for close shots. It sits just to the right front of my scope. I swnt some pics in. I put 100 rds. through the 357 and not one problem. The recoil on a 357 mag is sharp and has short tall spike in energy transfer. if anything could make this optic fail it would be that cal. I ran my show gun with 5.56 62grn green tips. I guess approx. 500 rds. no problems with zero. I am about to purchase several more for other AR platforms includibg SBR's and pistols with binary triggers. I will report how the AT3 handles
near full auto 60rd drum mags. I have no doupt through many majy years of gunning.. the AT3 red dot is the most optics you can get for the money. Gary in NH

Great sight

Mounted on a Mossberg 930SPX--co-witness with the GRS. Very well made. Will probably buy another. Love it.

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

Bought this months ago. I zeroed this red dot and put about 500 rounds of 7.62x39 out of 7.5" AR. It is still zeroed. It gets tossed around and banged into inside my vehicle, Not a single flaw. I dont bother with the rubber armor it came with because I simply don't care enough, but the optic also doesn't seem to care. Absolutely worth the money!

Red dot

Great value. Solid construction. Zeroed well. Red dot is not is not a clear circle. Glass seems chipped on one side. Just shot it once. I will return this one and try again.

Sorry to hear about the issue, Christopher. Please reach out to us so we can further assist.
Great Value

First off, vary fast shipping. The package arrived one full day before estimated tracking date, that's always nice! When I first opened the box I was impressed with the initial quality, especially for the price point. After I mounted it to my budget build 300 Blackout pistol, I was impressed with how sturdy it felt and how nice it looked. The lenses are nice and clear, the 2moa red dot is crisp. So far no problems at the range holding zero. I personal don't bash my guns around, But if you are curious about durability, check out the torture test video on you tube. Great value at under 100.00$. Would defiantly recommend to a friend.
