AT3 Tactical RD-50 Reflex Red Dot Sight - 2 MOA Compact Red Dot Scope

I just recently ordered my 4th scope for what I do I see absolutely no reason to spend more money on one, I have one on a Ruger 10/22 another on a Benelli technical home defense 12 gauge one on my Raven crossbow and the next one I plan on putting on a Winchester 22 mag the battery life is incredible, fairly simple to site in and I'm sure I'm going to own two or three more before I'm done I would recommend these to any recreational shooter or Hunter good luck to all.

I have had this red dot for about two years now. I bought it here on Amazon. I had a need for a lightweight, decent quality and affordable optic. This is a good one. I have an astigmatism in both eyes, so I see the red dot and a bit of a snowflake effect. This defect of the eyes has not stopped proper operation of the AT3 optic. I can still hit on target at various ranges. Funny enough... if you turn down the brightness on the optic, the effect of the astigmatism decreases. Myself and my mother have it, but my father and two sisters do not.I could not detect any parallax, being trained years ago at my job to spot it. If you look at the optic and shake your head left and right somewhat quickly, that red dot would dance around if there was severe parallax. The dot remains on the target as I bring my eyes up to it. I can't really say what brightness I use it at- I dial it in if I have time to about what feels comfortable for my eye. One feature I really like is that I can "half turn" the brightness dial to turn the optic off, then repeat the process to get the desired number intensity that I want.I use the bikini covers when I can, but not often. I've misplaced one of the turret caps, but that is my fault. That turret has held up just fine. After purchasing the optic, I noticed that the sales description did not state whether the optic would take the recoil from a 12 gauge shotgun. I got a fast response from the company: "Yes, it will take the recoil of a 12-gauge". So on the shotgun it goes! I have not noticed a loss of zero, even on a Keltec Sub 2000. I have a second unit for another long gun and would consider this affordable option for future needs. I happen to like these tubed, 20mm to 25mm red dots.

Placed on a Winchester Wildcat 22 rifle. Easily adjusted and got on target. Pleased with the price and quality of this scope. Functions as described.

I eval'd the Bushnell and Feyachi. All 3 made in China. The AT3 and Fey have the gas fill port/screw potted. The AT3 has a threaded insert in the mounting clamp which will definitely improved life and durability. The AT3 and Bushnell have springs between the clamp and housing to help expand the pic clamp. The AT3 is clam screw (Torx socket) is barely long enough to allow it to easily go over the pic rail and not un-thread from the clamp. (i've contacted AT3 directly to express my dislike with the length of the screw. i've been to the range and had to scour the floor for the parts when they come loose during installation. The AT3 LED/Red Dot power/brightness knob is firm between detents, more firm than the Bush and Fey. Finally, the AT3's windage and elevation screw covers compress the O-ring whereas the Bush and Fey cover the O-ring. The Fey has protrusions on the covers that can be used in the W and E screw, very handy. All 3 zero'd great and at 25yds i could keep a 1" die group easily with 10 rounds from my Buck Mark. I'm staying with the AT3 for now due to the lifetime warrantee and the dot clarity (my lousy eyes, for some reason, like the AT3 dot the best). Thanks

By looking at the picture, I initially though the red dot sight maker just replace the LED with a smaller one on the Bushnell sight and sell it under a new name. I was wrong. After receiving the RD-50, I have found that they are different. The RD-50 is about 15 to 20% smaller, lighter and better built than the TRS-25. It does copy the successful style and features of TRS-25 but it looks more refine. The LED is at the same place but it's much smaller and installed without showing the glue. The optic is clear and without distortion. It's not 1:1 glass but rather be a 1:1.3 (estimated) optic. This helps me see the target much more detail with my 58 year old eyes. I read some complaints about the fussy or the 3 MOA dot, but the reviewers did not know how to use or how to test it. Here these are my secrets:- To overcome my old eyes, I make a peep sight (a black tape with a tiny hole) and stick it on my shooting glass. This help me to focus better both the dot and the target. Try to focus at the dot not the target when you aim; this will improve your accuracy.- To see the true size of the dot, put a white paper under a bright light then aim the dot on the white. This will decrease the contrast and the dot will appear sharper and smaller. Red dot on black target is the worst on my book. I have 3 TRS-25 (and still love them) both with gold and white letter marking. The dot on the RD-50 is seen smaller than the 3 MOA dot on the Bushnell so I have to believe that it's 2 MOA.I don't have an Aimpoint or a Primary Arms red dot sight so I don't really know how good they really are against the RD-50. However, I have found that the RD-50 meets all of my requirements (all of those from the TRS-25 but with a 2 MOA dot so I can aim at the 2 inches target at 25 yard better.) the 50K hrs battery life is a bonus.As a sport shooter I don't need super duper optics that can survive the battlefield but cost a fortune. I have all the time in the world to replace a broken gun sight. For another bonus, AT3 gives us a lifetime warranty on the RD-50.I recommend the AT3 RD-50 red dot sight. It is a great improvement over the Bushnell TRS-25 period.

Got a bad one? Mounted on a 22lr pistol went to sight it in and thought I got it. Started shooting and couldn't hit my 12×7 target at 25 yards. Went back to paper and shot from a supported position at 15 yards and the impacts were all over the place. Customer service is great. I contacted them directly yesterday and they shipped a new one today. Just had to show proof of purchase.Hopefully the new one will work. It's a 22 lr pistol! Not much recoil. I will update once I get the new one.
