      AT3 Magnifier

      Great product, excellent clarity, rock solid base. I had contacted customer service about changing bases for my red dot and buying a magnifier, they sent an email back to me with it all in my email all set up ready to order. It made my buying decision so much easier. I plan on ordering more products very soon.

      Thank you for your feedback, Rusty! It's our pleasure doing business with you. -- LM
      Worth the money!!!

      As you can see below, I wrote a previous review on this magnifier and mount assembly. I am extremely happy to say AT3 reached out to me without hesitation and replaced the mount in 1 day. (THANK YOU AT3 STAFF). I was already very impressed with the magnifier, but now with this new tight mount, YOU CANT BUY A BETTER SET UP. THIS THING BLOWS AWAY ALL MY OTHER red dot magnifiers.
      BUY IT!!!

      We really appreciate you taking the time out to share your experience with us, Robert. We work hard to meet expectations like yours, and we’re happy to hear we hit the mark for you. Cheers! - AB

      Way under priced. Sharp crisp beautiful picture. I recommend this without reservation to all.

      We try our best to provide products that are cheap in price, but not in quality. We appreciate your feedback, Hector! -- LM
      Great Value

      This is not an expensive optic so it shouldn't be compared to one, be realistic. The magnifier works great, I have it paired with the AT3 LEOS Red Dot Sight, and it was significantly cheaper than any other product in this quality range. If you purchase this with the understanding that you're paying sub $100 for a good quality magnifier then buy it, if you want to spend $300+ on a more expensive and better performing optic then purchase one of those instead.

      Thank you so much for your detailed review, Mitch. We really appreciate you taking the time out to share your experience with us and we're glad everything is working out so far. We count ourselves lucky for customers like you. Cheers! -AB
      Good optic - recommended

      Matches up neatly to the AT3 RD-50 with minimal adjustment. Optics are clear, operates smoothly, good price. I like it!

      Terry, thank you for the great review! We’re so happy you like the product. We count ourselves lucky for customers like you. Cheers! - AB
