AT3 compared to bushnell and primary arms
on July 9, 2017
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 category
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 stiffer
All 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 )
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 zero
The 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.
I would rank them this way on performance and quality
However 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.
