AT3 Tactical RCO Red Dot Sight with Circle Dot Reticle

I'm thoroughly impressed with quality of this sight. It's really nicely finished. It looks, feels, and functions like units that are WAY more expensive. The included mounts are solid as well and allow several heights and configurations. The glass is super clear and the reticle is sharp. There is plenty of brightness settings. I used it in dim light under cover at an outside range and bright indoor lighting as well with no issues. It has also worked perfectly in bright sunlight during outdoor USPSA matches on my AR9 PCC. Reticle is quick to pick up and get on target quickly. If I could change anything I would prefer a 30mm tube but it works as is. I will probably buy more of these and recommend it highly. GREAT Value!!

23 Jun 20 Update: The new replacement optic was received and my initial issue were corrected. Cant fault them because this is a new release optic. Not my favorite acss style reticle but it does the job!Pros:Very clear glassGood reticleLightweightSturdy BuildComes with a boatload of accessoriesBudget friendly!Cons:When going back and forth between objects the reticle is stuttering.Can definitely see the emitter from the front of the optic!All in all i thinks its high value and low budget with plenty of mounting options and quality lens covers and bikinis. Cant really say its good for duty use but i think plinking would be nice.Future update for when this optics get some range time in.19 Jun 20 Update: I was able to get in touch with the company and express my concerns. They quickly and respectfully responded and are sending a new one. Fingers crossed but im hopeful for this new one.I really like how the sight is really lightweight however it feels as though its not durable. This is just at first glance and no range time yet. I have my doubts for sure. The circle dot reticle is what i was looking for but it is not crisp and has a really low refresh rate so when scanning up down left and right it seems as though the reticle is skipping across the surface. No sure if i should see if this is just manufacturing issue but i have plenty of low budget optics and this does not cut it.

Initial impressions.Seems to be a good build quality. It doesn't feel cheap. Riser mount feels solid. Even with my astigmatism, I can see the dot and circle quite clear in comparison to some other dots. Although I will note, indoors it still seems fuzzy, but once you are outdoors it clears up. I will update this review after a trip to the range.

I'm very impressed with this red dot. The circle dot reticle is very nice. The red dot came with all the mounting hardware needed for any application. It came with a battery in the unit and one extra battery. Mounting this red dot was very easy to do. The unit is very bright and easy to look through in any light conditions. Nice touch from AT3 Tactical was a follow up email with some PDF files with three different targets to print off, for use in sighting in the Red Dot once it is on your rifle. I will buy this red dot again for my next rifle.

I like it. Had some some problems with the reticle being a little off and not super clear. Also was a bit hard to sight in. Figured it was good enough till a little black piece of something showed up on the inside glass. So I contacted the manufacturer and they sent a replacement with a prepaid envelope to return the old one. The new one is perfect. Sighted in quick and no issues.I like the reticle, glass is clear and without noticeable tint or distortion. Good field of view. Plenty of brightness settings for anything from nighttime to bright sun, and it remembers the last setting when you turn it on.This sight is exactly what it's supposed to be. Not the best, but pretty good, and excellent warranty service.

I picked up this particular Red Dot from AT3 mainly because of the 2 MOA with 62 MOA reticle display. Excellent target acquisition with adequate FOV for my application. I paired the RCO with my new FM AR-45 in 5.5" configuration. The RCO was easy to sight in and with the heavy blowback of a .45 its holding zero fine as several hundred rounds. If you are looking for a high quality Red Dot with an excellent price point AT3 is the way to go. Additionally, their warranty coverage and phenomenal customer support is an added bonus. Highly recommend this product.

My only con was when I was out hunting coyotes last week, the sun was very bright and with a couple of inches of new snow, I had some trouble getting the lit red dot and circle bright enough to see against the snow. I’m not sure if any other more expensive red dot would have shown up any better in the same conditions. It was extremely bright out with the sun and the snow! Otherwise it does exactly what it is supposed to do!

I can't speak for no one else,but the RCO was everything I hoped it would be once it came/Not to heavy,not to lite,super clear glass,big field of view and clean circle dot reticle period!!! Also for the price point I think it's worth it.👍However if I had a "WISH" list,it would only be to add "SHAKE-AWAKE"💪😁other then that I was truly "NOT" disappointed.💯Good job AT3!!!👍
