Customer Reviews
I purchased the AT3 4x magnifier to run on CETME-C behind a Holosun 1-MOA red dot. It’s a love/hate relationship with the 4x. Glass is crystal clear, and the 1913 QD mount is firm on the rail. Biggest issue was finding a happy medium between eye relief and distance between magnifier and red dot. The flip-to-side function is stiff which, on one hand, is great and will not accidentally flip. On the other hand the button is in a tight spot even with a riser it’s a small struggle, but altogether operates as it should. The last issue I believe can be fixed by myself with a little thread lock and tension - the magnifier has some play inside the round clamps. This of course creates issues with holding zero, but something I believe I could fix. Overall the best features are the clear sight picture (once you find the eye relief) and the variable magnification. Looking forward to more AT3 products!
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.
It is a 4x magnifier that works. It does the job but you can definitely feel it’s a “budget” option. It’s very heavy and the push button is very stiff. I left it compressed overnight to try to make it less stiff and it kinda worked but I realized that it doesn’t really matter because if you put any turning force on the optic before pressing the button fully, then the friction of the metal will cause the rotating joint to lock up and not flip with any amount of force. So you have to consciously fully depress the button and only then apply turning force on the body. Additionally the springs on the retaining slide thing have come out twice and I had to put them back in and I had to retighten some screws lest it slightly pivot right/left.
The clarity is good IMO and it does feel durable being made of metal.
Despite the above, I’m not upset about it and don’t plan to return it.
If I could go back in time I probably would have spent alittle but more money to get a less heavy optic with different flip mechanism (button sucks). But if it’s between this or nothing, then I would 100% recommend getting it. Having the ability to magnify your red dot is so nice and it’s able to hot-swap between your guns as needed without messing with the zero.
Very nice.

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.
