Magnifier with red dot
I guess it does what it is supposed to but in order to use it you have to shorten your but stock all the way which makes the rifle impossible to use, for me anyway, I saw lots of people using it this way on youtube, but for me it didnt work. It is one of those things that you would have to try in order to determine if it works for you.

Great value magnifier
For the most part I love this magnifier. My only issue is the SHORT eye relief. I would love to see this addressed with a future product.

Battle Tested
I picked up this magnifier back in 13-14 for Afghan, and it made me feel like a school girl taking a sip of pumpkin spice anything when the fall hits . It went through a full grunt deployment of banging around, getting grimey, and going through quite a few nasty fights. Never had an issue with it. Even with constant flipping back and forth for near and far use, and tons of rounds (suppression is the name of the game baby), it stayed sturdy.

I ended up unscrewing the magnifier from the mount, and rotating the mount 180, and screwing the magnifier back in, so the flip to side push could be on the right side. The switch kept the magnifier from pressing against my kit when walking around if I had it flipped to the side.

Now, I'm a righty and normally shoot from that side and I always want my weapon up and ready to fire if I'm in a fight. Moving the push to side on the right might not make sense since it's harder to use your non firing hand to make the move. That being said, some practice easily resolved that issue and I was able to do smooth switches under fire while keeping my rifle pointed in the direction of turds.

I've kept the bad boy and have been using it here and there at the range for about 6 years now, post deployment. Still no issues.

All in all, this magnifier is awesome and rugged, and I think it secretly likes the abuse. Get out there with it and get dirty!

Solid magnifier!
The fit and finish of this magnifier are possibly the best at the price range. I compared to others and this was definitely the best. I like the flip down mechanism and it works very well. It is easy to center the red dot and the clarity is second to none. Very happy with my purchase.

Totally Amazed by their durability.
I bought the 3x magnifier had the gun shop install it but obviously they didn't mount it correctly. Or maybe I'm supposed to tighten it up after so many shots. I dont know. But at the range today it fell off while shooting and hit the ground from about 4 feet. I just mounted it back on my AR15 and continued shotting. And then was hitting 6" steel plates at 200 yards. Very pleased with the build and quality of Vortex. I'm sold.....

I bought this magnifier 6 month ago before being deployed abroad in a desert environment. The intent was to pair it with an EoTech 552. Both make a good duo and I’m glad I had the VMX 3T.
I especially like the durability and the clearness of the glass. Plus, the flip system survived the sand and was always reliable.

Thanks Vortex for this product.

Excellent quality, just mount and shoot. No need to check hardware torque, I've put 2000+ rounds down range since I've mounted this behind my eotech xps2 and haven't had any issues with hardware backing out. This magnifier REALLY clears up grainy holographic reticles.

Doubles the capability of the Crossfire
I put this magnifier behind my Crossfire (also a quality sight) and it more than doubled the capability. It increased the range but can be flipped out of the way for closer in, best of both worlds. I'm right handed so I switched it to flip to the right rather than left so it does not block both eyes from vision when just using the Crossfire.
