desertcart.com : AT3 Tactical RD-50 PRO Red Dot Sight with .83" Riser - for Absolute Cowitness with Iron Sights - 2 MOA Compact Red Dot Scope : Sports & Outdoors

Review: Quality build and product support that other Mfgs should take a page from - This is the first AT3 Tactical product I've purchased. As a retired LEO with 30 years in the field, I've experienced several department issued optics, all cost north of $500. For the money, the AT3 Tactical is impressive in both form and function. Right out of the box, you can feel the quality of this optic. It is compact and clearly well built. Small as it is, it feels substantial. It's a serious device. The red dot was easily acquired and plainly visible in bright sunshine. It was nearly zeroed on my first shot with it (mounted to a 9mm carbine) and after an initial single click adjustment for windage, it held zero through 200 rounds of running and gunning, slinging and banging around. That this has a TRANSFERRABLE LIFETIME WARRANTY is icing on the cake. At this price point, I haven't seen a better optic and Officers are notorious for buying everything from soup to nuts in trying to find unicorn devices for their long guns - I've seen dozens. I am very pleased, obviously, with this purchase and I've no reservations about recommending the AT3 Tactical for anyone interested in a low-cost/high-performing optic.
Review: A real gem: From fast delivery to delivering on the range! - Mounted the AT3 RD-50 PRO an my most recent AR9 pistol build. Matched up on pic rail perfectly with no play or wobble. Dot is crisp and clear. Glass is really quite good considering cost. Adjustments were tactile and audible, and allowed straightforward zeroing with only 15 rounds, including a five round group to confirm. Targets shown were shot offhand at 20 yards, which seemed like a logical zero for a 5” barrel length bag gun. All in all, I like almost everything about this red dot... What’s NOT to like? I feel the rubber armor is a bit fragile, and seems a bit of an afterthought to me, especially the lens caps, which won’t stay connected and out of the way. I’d prefer much thicker armor, and more positive mating of the lens covers. Does this really matter? No. Has nothing to do with the actual effectiveness of the optic, and is more than outweighed by the included riser mount which seems of good quality, and is a pretty classy looking attachment method. Fantastic value. Great battery life. Really useable dot that gets plenty precise and can also be bright enough for any outdoor conditions I can think of. Comes WITH MOUNT, (PRO model). Armor could be better, but at least you have some protection. Lifetime transferable warranty. Highly recommended.

## Questions & Answers

**Q: I have an m&p sport 2 with magpul front sight and stock front sight. will this red dot work as far as co witness?**
A: Yes, works great!

**Q: Does this sight have auto-shut off?**
A: even though it boasts a 50,000 hr. battery life you would be under the impression but it DOES NOT. It is a well made sight, and I am pleased with mine so far but if you must have you weapon in an "ready" state at all times this might not be the option for you.

**Q: Since the mount has been reported to break, is this compatible with any other more reliable mounting systems?**
A: I have one on a 50 Beowulf AR-15. I've put well over 200 rounds down range and the mount seems to be good as new. Since the mount is a standard picatinny rail you should be able to find one the same height and use that. I'm not sure if you can find one that features the co-witness option though.

**Q: Is this sight parallax-free?**
A: Short answer: yes. Nothing is 100% parallax free. EO Tech has been proven to be the closest. I have multiple red dots spanning a wide variety of price points. The AT3 is by far the most economical red dot that is still considered “parallax free”. This is a very good optic for the money. Probably the best “bang for your buck” available.

### ⭐⭐⭐⭐ Good sight. Rebranded Bushnell???
*by S***2 on November 24, 2018*

This red dot is amazing. Bought it after watching 704 tactical beat the snot out of it. Clear glass. Crisp red dot. Rubber armor is iffy though. Caps barely lock together. The rubber attracts dirt and hair like crazy. I tossed it. Mount looks good and is nice and sturdy. Looks like a Bushnell clone. The are the exact smae dimension. I have the Bushnell on the a Ruger pc9 and couldn't tell the difference between the 2 other than the branding on the side. I got this for $79.99. bushnell was about $60 without the mount.
