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

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.

Excellent budget red dot. I have the TRS-25 from bushnell and from primary arms the MD-RGBII and the MD-ADS. These I will compare the AT3 to as the are popular choices in the budget red dot categoryBUILD:Appears to be aluminum tube with solid dials. Markings are well painted and positive non audible but tactile clicks.Very similar to the TRs25. The dials feel and look identical. The primary arms offer two versions push button and similar to the TRS25 and the AT3. The primary arms dial is stifferAll 3 are of similar quality construction but the bushnell finish seems inferior or the copy I have had a flawed paint job. All offer a Allen screw base to clamp to your riser ( I recommend the UTG. Inexpensive and work well )PREFORMANCE:all 3 hold zero on a Baretta cx4 carbine in 9mm and a AR 5.56. All three I was able to use the quick release and put back on and not notible change in zeroThe dot is the same as the TRS-25. Its smaller than a 4 dot size but not as small as the 2 dot size of the primary arms models. I would guess it at 3.The AT3 dot is not as sharp as the primary arms but sharper than the TRS-25. Minimal difference between all and only at all notable in side by side comparison.CONCLUSIONI would rank them this way on performance and qualityPrimary armsAT3BushnellHowever adding price into the mix I would rate the AT3 the highest. The reported life of the battery is 50k. It's an unknown as it has been on the next to lowest setting since I got it and still working fine.All use common watch type batteries.

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.

looks great and works well

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.

Nice solid built... Quality.

Loved the optic! But when I went to the range with a 410 shotgun and 2 1/2in small game shell the mounting screw snapped off on the third shot!!! That design was the absolute worst I only found a couple pieces and now have to return it right before turkey season!!!
