This is the nicest and inexpensive red dot that I ever had reviewed many of them including the expensive ones this one do for me and meets my needs thank you guys for this good product including the magnifier great products

Thanks for sharing your feedback, Juan. We're glad you're satisfied with your purchase. Cheers!

Really good magnifier, can be set to flip both to the left or right which is great me as a lefty shooter. Ive used it out until 100 yards and works great at that range (with the 2 MOA AT3 rds). Happy with the purchase.

Thanks for sharing your feedback, Chris. We're glad you're satisfied with your purchase. Cheers!
Red dot plus magnifier

Both the red dot and magnifier we're easy to install and worked as advertised. They were easy to zero at 25, 50, and 100 yards. I was pleased to be able to flip the magnifier to the right so the iron sights could be used.

Thanks for sharing your experience, Gary. We work hard to meet expectations like yours, we're glad we hit the mark for you. Cheers!
AT3 kicks ass

My RRDM magnifier is great!! Getting a little older and it in line with my RD50 red dot make up for my
aging eyeballs! I am sold on AT3 products and their outstanding service. I have been a shooter since 1959
and have bought a lot of related products and I seriously believe that they are the best company that I
have dealt with. I would put their products head and shoulders above any other similar stuff both in
price and quality.

Thanks for sharing your feedback. We're glad you're satisfied with your purchase. Cheers!
Great Magnifier!

Well update to my last post. The magnifier is great and is Crystal clear.

Problem I had was with the mount itself. Got in contact with AT3 was sent a new mount. This new mount is solid as can be and I do not expect to have any problems with it.

The old mount I had was the earlier version, the mount has changed since then and it is a much better design in my opinion.

As for customer service I have never dealt with a company that is so compassionate in standing behind there products that they would do anything to fix a problem a customer is having.

Thanks for sharing your experience, Brian. We work hard to meet expectations like yours, we're glad we hit the mark for you. Cheers!
