AT3™ 4xRDM™ 4x Red Dot Magnifier

These things work GREAT! I have several 3x & 4x magnifiers plus their Red Dots with Laser, and all work GREAT!

Thank you for the kind words! We are glad to hear that our products are serving you well.

Not good for duty use

I wanted to love this as much as I love the at3 red dot I bought for my duty rifle. Unfortunately, this magnifier keeps moving from the vibration of being in the rack in my squad. The magnified red dot is centered at the start of my shift, it is way left or right by the end. As I look through it all I have to do is tap the side of the magnifier with my palm and watch the red dot move all over the place. They very quickly sent me a replacement so definitely 5 stars for customer service, but the replacement one did the same exact thing. Time for a refund.

Thank you for bringing this issue to our attention. We apologize for any inconvenience caused by the movement of the magnifier. Our team is dedicated to providing high-quality products, and we are sorry to hear that this one did not meet your expectations.

We have taken note of your feedback and will work towards improving the design to prevent any movement in the future. We truly appreciate your loyalty to our brand and hope to have the opportunity to make it right for you.

Please reach out to us for a full refund, and we would be happy to assist you. Your satisfaction is our top priority, and we thank you for giving us the chance to address this matter.
