Frequently Asked Questions
Q: How do I know which riser mount to get?
A: For AR's, we generally recommend the .83" mount, since it puts the red dot at basically the exact same height of Mil-spec iron sights. That means if you have a front sight, the red dot will be just at the point of the sight post. This is called "absolute cowitness"
Either of these mounts will work, it's really personal preference. For most people, the .83" mount seems to be the right choice, and it's the most popular. If you would like, you can get the 1" mount and it will sit a little higher than the iron sights. Now, if you have a front sight, it would appear in the lower 1/3 of the red dot sight's window. That is called "lower 1/3 cowitness"
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.
Q: How are your prices so low?
A: Since we sell AT3 products directly to the customer, vs selling through a distributor, we are able to pass savings on to you.

The sight is Good
I picked up my first AR during the first weekend in December. It was a used AR I picked up at the gun show and it was a complete A2 AR. Had some modifications made to it and ended up upgrading to a free-float handguard, newly threaded barrel, and threw on a Magpul flip-up front sight. Was wanting to put some sort of optic on it without spending more than the entire rifle itself. I settled for this particular red dot over the Bushnell TRS-25 which is what it seems most comparable to. In the end, it did exactly what I wanted it to. I needed something that would suit my A2 appropriately without being too bizarre. I'm happy with it and would definitely recommend it for a budget AR build.
I ordered this for a budget AR build I was working on. The product looks identical to the Bushnell TRS-25 Red Dot but according to the description it has a 2 moa dot instead of a 3 moa dot. The battery life for the A3 is described as 50,000 hours on the lowest setting and the Bushnell TRS-25 is supposed to have 3,000 hours of battery life on the #7 setting. I realize now I wasn't comparing apples to apples. I'm not sure what the A3 battery life is on the same setting so it'll be interesting to see.
The package arrived very quickly so I was impressed with the speed of the shipping. The optic was well packaged and after installing the battery I mounted it on the rifle. I headed for the range and I zeroed it at the 25 yard line. At 25 yards it was about 5" low and only about 1" to the right. The plans for the rifle is a 50 yard and less plinker and maybe some short range 3-Gun stuff. One of the clubs I shoot at has a quarterly 3-Gun but one of the bays sometimes has targets out to 300 yards.
The red dot is clear with a slight bursting of the dot on the brightest two settings. That being said though my eyes aren't as young as they used to be and 16 years ago I had LASIK surgery. I don't know how to tell you if that contributes to the star-bursting. The red dot seems robust enough to handle a little abuse and definitely seems like it will hold zero but only time will tell for sure. The only problem is that the rifle might only see periodic use as I have several others more suited to 3-Gun. I purchased it with the .83" riser and it co-witnesses nicely with my front sight.
The finish on the product was good and the dials have a positive detent and are firm enough on the turn that it won't move between settings on its own.
Overall I'm happy with the product and I have recommended it to friends for their builds.
I ordered as an upgrade to a basic AR. I didn't want to spend more on my optic than I did on my firearm but wanted a decent entry level red dot. This shipped extremely fast and came before I expected. It was easy to install and fits securely. It is a feature rich optic with a bargain basement price point. I could easily have spent 5-10 times what I did on this and ended up with something that was not only more expensive than my firearm but also about as accurate. I have no complaints. It co-witnesses perfectly with the BUIS I purchased here as well and seems to be secure, durable and accurate after 500 rounds. I only wish I would have read the instructions prior to "playing" with it as I didn't notice that it would have only required but a few clicks to sight in. Oh well, I wasn't upset with a few more rounds in the lead sled to adjust it back. Great value and surprising quality.
I am so impressed with this red dot site. It is an amazing value. I just spent the weekend at a huge gun show (INDY 1500) looking at all the available products and saw nothing that even came close to the AT3 RD-50 at the price point. I basically feel that this RD saved me $500 as I was about to by a Trijicon MRO.
I have the the red dot mounted....haven't tried it yet. I am very happy so far and am excited the way it sets up on my AR.
I would most certain purchase again from AT3 Tactical....Thanks Mike
My husband loves this scope and I cannot rave enough about the customer service! Soooo wonderful!!
Very pleased with optics. Fit perfectly on the rail of my m-15. Highly recommend!!!!
I put this on an AR 7.62x39 it co-witnesses perfect with the red dot sitting just on top of the front sight post at 100 yards.
Well made. Easy install. Fairly accurate, red dot did not shift after 100 rounds. Had it mounted to close to the rear iron sight. Which resulted in shooting lower from intended mark. Going to move the sight further front and retest. Initial use is very positive.
Too bright, at 10 with a new battery. I just use #1 setting. Well made and quick delivery.
I haven't had the opportunity to use the red dot, but it was simple to mount along with the optional .83" riser. It seems like a quality product with a great fit and finish. At3tactical processed my order quickly and the product arrived fast. Great company to do business with!
Great product fast shipping
Received sire before receiving ar 15 that the site
Will go on...
Quick and speedy shipping. Received it mere days after ordering it. Very solid build with a tight attachment to rail. Zero wiggle. On point with a windy 22° ND day with blowing snow at 50yds. First shot after zerod in, the tannerite did not stand a chance (50 yds buried in snow). No added weight. Will be a repeated purchase for further AR builds. Great product! $80 can't go wrong.
Reviews from other sites were exceptional, can't go wrong. Beats the eBay crap out there. When I buy my next rifle I'll put another one of these on it. Thanks at3.
The mini red dot sight works flawlessly.
Nice red dot. The .83 riser was a perfect height for an AR.
Fit and finish excellent; works very well. Don't spend 500 when you can buy this for 80.
I have several red dots and short scopes I use on various rifles. Decided to try this one considering the reviews and the price. So far, it is working very well, sighted in easily. Have one mounted on a M&P 15 AR type, have put several hundred rounds w/it so far. Also bought a second red dot and mounted on a VEPR 12 gauge and after about 80 rounds, still holding true. Going to try it soon with a 12 gauge drum I bought for it and rapid fie test it. Will update as needed, but happy with it enough to have bought a second one.
Perfect for the price, installation is simple and had it zeroed in with 5 shots on target! I also notice with this scope it is easy to shot with both eyes open! Quick target acquisition! Make sure you order the 1" riser!
I ran across this sight in a "under 100 bucks" red dot review, where it was highly praised. I am very happy with the purchase, they were a big success as Christmas gifts. The AT3 RD-50 appears to be a top quality sight and makes a great flattop AR sight. Mounting was quick,easy, and to my surprise, on paper with the first shot. Made zeroing fast and easy. Keep up the great work and fast shipping. This is a winner that is sure to last.
Great product great service great price what more could you ask for
This sight is an amazing product for the price you pay for it. Would definitely recommend
I put the RD50 on my S&W AR15/22. Took about 7 shots to zero at 25yds. and it's good to go! The grandkids have always loved the AR and the red dot made them all super shooters. My wife wants a couple more for her guns. Fine value, excellent instructions, very accurate. I'm happy with the purchase.
Easy installation. Easy adjustment. Excellent performance. The 2-MOA dot is perfect for the ranges (and targets) at which I'm shooting most often.
Great optic. Got it zeroed quickly and it stayed zeroed after 250 rounds of 556. Cowitnessed with my magpul BUS easily.
LOOKS GOOD SO FAR.........CO-WITNESSED PERFECTLY WITH FRONT TOWER USING .83 RISER. LOOKS GREAT , TOO........NICE AND COMPACT !
Got my sight in the mail today mounted on my m4 .Best money I have spent in long time new to AT3 Products and I love them thank you Merry Christmas
I installed the Red Dot and .83" riser on my Colt LE6920 M4 Carbine. Installation took a couple of minutes and was very easy. The adjustments needed were very minor to zero-in the sight, and very easy to make. I have fired less than 20 rounds so far, but it appears to be exactly what I was looking for as far as price, quality, and ease of use.
Fitted this sight to a custom Blackout build I've put together and very impressed with the fit, finish, and features. I'm very impressed with the sight, but have not had a chance to do more than get it sighted in at 25 yards. Weather is keeping me from going out and finishing my sighting in at the moment, but the first chance it gets above freezing I'm heading to the field. Can't wait to put it on paper!
I just mounted and put about 120 rounds through my AR15 with this sight. Worked great. Took some time to sight. I wish I would've bought the riser though. Also would be cool if the red dot similar to Eotech. Was hitting metal gong at 300 yards with this.
I searched all of the literature and found several reviews on this product. Best quality & best price for my needs. Put it on my Ruger 10/22 and it is great. Everything worked just as it was stated. Plan to get another soon for my AR.
Very well made quality product at a price that can't be beat
First red dot sight ever purchased. Have used others but priced out of my reach now. Needed a quality, inexpensive optic for my sight ready carbine AR. Easy to install & zero. Will pair soon with iron flip sights to cowitness and put the gear through it's paces. Crystal clear lens, nicely coated with no nicks or scratches, respectable 2 MOA dot for close range. Fastest shipping and delivery to Carolina I have experienced for FREE! Thank you AT3!
I received the RD-50 about a week ago. Set-up was ultra easy. Sighting in took just a few minutes. I can't speak to long term durability yet, but this has to be the best value in a red dot sight in this price range. I sighted in and shot under bright skies - no problem picking up the dot under those conditions. Accuracy was right on the money every time. To top it all off (literally), this sight looks great sitting on top of a black gun. A small unit with lenses and controls large enough to use easily. This is my first RD-50, but probably not my last! AT3 Tactical and their products are spot on. Get one of these sights - you won't be disappointed.
As I bought the AT3 Tactical RD-50 Red Dot Sights as Christmas presents I have not had an a chance to try them out. Try me again in January.
Mounted the RD-50 with ease. Used directions to zero in the scope. So far, so good.
Setup was very easy took me less than 5 minutes very compact very nice Red Dot everything I wanted thank you
Shoots with incredible accuracy after taking just 4 shots to zero. Highly recommended! Best Red Dot sight for under $100 on the market. Guaranteed. Also highly satisfied with at3tactical and their extremely fast shipping.
This red dot is a great product at a great price you can not go wrong. It also arrived several days before expected.
Best bang for buck red dot sight HANDS DOWN! Easy install and 1 click off sighting it in at range this weekend.Full co-witness with med. riser.On the fence about red dots?Fall your ass off on the AT3 side and get one ASAP!
Great looking sight. I like the small size and it fits perfect. I like the fact that I can still use the iron sight if I choose to.
Small and compact, mounted easily and securely to my AR-15. The fine 2MOA red dot is an improvement over other sights with larger dots. Available range of intensities are sufficient to cover all shooting situations. Easy to sight in and held zero all day through 100rds of 300BLK. Entirely adequate for much less than the cost of other 1x Red-Dot sights.
I enrolled in a two day rifle training class (about 500 rounds each day) and really wanted to train with a red dot. Last year I used a 3x scope and have been in the market for a red dot for a while now. With the training only two weeks away and still not being ready to purchase something for $400, I found this red dot for $75 bucks. I took the gamble thinking if it fails, I'll just go with my backup iron sights and use the red dot's 3 year warranty.
IT WORKED THE WHOLE TIME! This little red dot kept up. All 1000 rounds, two days in the dirt. I didn't notice any problems. I got the medium riser so I could have absolute co-witness. I ran the whole thing at max brightness during the class. I'm glad I bought it, and I plan to use this for a good long while until I upgrade (think several years).
Received my RD-50 Micro last week and got it zeroed at the range on Saturday. Very easy procedure. Dot works great on my M&P 15 Sport II. I got the 0.83" Riser and the Red Dot perfectly co-witnesses with the front sight post. I'm new to AR's and this Red Dot made the sighting effortless. I would definitely recommend the sight and by one for any other rifle I might buy.
I'm very happy with my purchase of the AT3 RD-50. I bought both riser mounts, but ended up using the .83" for absolute cowitness. This is the best red dot for the money... hands down. Worked great at the range. I had a question before ordering and their communication was quick, helpful and friendly. The shipping was very fast too.
Really impressed with the quality feel of this AT3 Tactical Red Dot. Received shipping information immediately after placing the online order. With a 2MOA, I hope to add a magnifier soon to this setup and leverage it further out.
received sight, set up simple, riser set dot on front sight perfectly, quick zero in. Best bang for the buck I've had in awhile. Thanks
Great little red dot. Was just what I was looking for - something compact and lite. Holds it’s setting on my 6.8 after repeated shots. Very Pleased with the sight. The optional mount was perfect height. Very little adjustment for zero. Another great purchase.
Did a lot of looking around and research on red dot scopes and made the decision on the at3tactical rd-50. Now that I have tested it out I'm convinced I made the right choice.
Set up was quick, zeroed in right away. Meets all my concerns. Excellent website, quick professional ordering. Everything as advertised.
Well done. If your in the market for red dot scope, pull the trigger here.
It's been nearly two weeks since I ordered this. Supposed to arrive tomorrow. I suspect it's a fine little optic for the money, just one crazy delivery process. First it sat for six days in Fort Dodge, IA then over the course of one day's it arrived and left several times in Kansas City. Not AT3's fault but crazy "first class" mailing.
Shipping was quick. Optic easily mounted to upper with .83" riser and appears to function properly. This is a part of my first ever build and I didn't want to break the bank so this suited my needs. Once I shoot the rifle and zero it, I'll update, but happy so far!
Definitely worth the money, and then some!
Fast service. Received the day after I ordered. Rugged build, good looks, crisp clear bright dot. Took it to work for "show and tell" and two of my friends ordered one.
Firearm used- AR-15
Good field of vision weather mounted forward or rearward with a precise Red Dot. Mounts are solid, and install easy. Red Dot adjustable range is more than sufficient. My overall opinion is this sighting system is a good quality package at an affordable price.
My sight was delivered in 2 days and works like a charm. The price was excellent I will be buying more from AT3.
Nice quality, easy to mount, solid product and functions great! Very good buy for an optic under $100. Would definitely buy this item again.
