AT3™ 4x Magnified Red Dot Kit – Includes Red Dot, Riser, & 4x Magnifier

Can’t say enough about your customer service. I ordered my kit and the next day it shipped. RD red dot and 4x magnifier lined up perfectly once I zeroed in the magnifier to the red dot. I will know more once I get to the range. Excellent customer service(Alvin) and a solid product. You can never go wrong with AT3Tactical

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

Michael Davis
Great products

Highth of the red dot with riser lines up perfect with my magpul back upsights. Dot brightness knob has no play, so no worry about it turning while shooting. I just wish the magnifier was spring loaded to flip out the way.

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

Ron Boulos
So far a great product

The red dot works great as I knew it would and I actually like the magnifier more than I thought I would. Trying it on a 9mm AR pistol now,going to switch it to 300 Blackout AR pistol next. So far pleased with it.

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

Daniel Gallagher
First impressions

Quality is outstanding. I love the simplicity of the red dot and ease of installation. I believe the 4x magnifier was a bit to much for my needs and wasn't quite right for my rig but that's on me.

Thank you for sharing your feedback! We're glad you are satisfied with your purchase!

Red dot/4x magnifier

Sight was great, however the sight.and magnifier would not fit on my Riuger556 rail. It would take at least 2 more slots on the rail to install both. Thought I was getting a combo that was designed to work as a pair.
