Rated 2 out of 5 by from Great magnifier, terrible rye relief. Like all other vortex products, the VMX-3t is great quality. The magnifier actually makes the dot on my red dot even crisper. In the futer I’d like to see them go to maybe a 4x magnification, though. However, the reason I didn’t give 5 stars is because of the terrible eye relief. I’m not sure why vortex would design this with 2” on eye relief but it almost makes it unusable. With it mounted as far back as possible I still have to stretch quite far to see through the magnifier as intended. I can completely collapsed the but stock and use it which helps but I still have to stretch to get to the magnifier and as well as the fact that I’m using a collapsed but stock. Big time cortex fan but was pretty disappointed with this one.

Rated 5 out of 5 by from Best value out there I’ve had this for a few years now and it has yet to fail me. Glass quality is great, ease of use is outstanding and duribility surpassed all expectations. This thing has been bouncing around in the back of my car for years and zero issues. I’ve compared this to other magnifiers that cost 4 times as much and I have not been disappointed with how this compares to them. Everyone with a red dot should have this magnifier. The only downside to it is the mount, opens to the left (in the face of righties). You can flip the mount however to have it face the other way so it’s not a big deal. Thank you Vortex for the awesome product.

Rated 5 out of 5 by from Worth the upgrade! I was using a Vortex red dot on it's own at the range and really enjoyed the accuracy it added to my shots. Added this magnification scope and instantly the experience was enhanced. 3x isn't crazy but it is the perfect amount of zoom for seeing exactly where your targets are being penetrated at any indoor range. I shoot left handed and after reading previous reviews of how people were complaining about it swinging to the left, it is easily changed to swing either way. Glad I tried this out because I wouldn't want to hit a range without it now.

Rated 4 out of 5 by from Magnifier is great, but should flip the other way I recently bought this magnifier and find that the build quality on it is very sturdy and the optic itself is very clear. The lifetime warranty is unbeatable, but there's only one thing I really hope they improve or at least give the option for. Right now, it's meant to flip over to the left side. Being a right-eyed shooter, when it's flipped over to the left side, it completely blocks my view with my left eye while trying to shoot with both eyes open. Also, if I let the rifle hang by its sling with it flipped over, the magnifier would dig right into my body. It makes more sense for it to flip out of the way to the right. I have the mount flipped over to do exactly that, but now the release button is facing forward. So to use it, I have to reach over the optic (using my support hand so my shooting hand never leaves the grip) and pull on the button before I can flip it out of the way or flip it into view... It would be nice to have the option to have a mount that flips to the right with the button still facing the back so that it can be easily pushed...

Rated 4 out of 5 by from Another great Vortex piece I recently added this to my AMG UH-1 in my 300 BLK rig, and it does exactly what it's supposed to do - magnify. It perfectly aligns with the reticle on the Huey (thanks to the included shim for the mount), and it operates very smoothly and lock into either position confidently. My only nag (and it may not even be an issue for others) is that I wish it flipped the other direction; I'm right handed and it flips left, so when it's not deployed it is in my left peripheral, whereas I'd prefer it flip to the other side so I don;t have to look around it when not in use. Again, this may not matter to others; it is purely a personal preference. I could probably reverse the mount so it does flip the other way, but then the release button goes from an intuitive "push" to a tedious "pull", and I'd rather not do that. That lone gripe aside, it looks great, pairs perfectly with my Huey, and I have no concerns about reliability since it's a Vortex.

Rated 5 out of 5 by from Great 3x magnifier I bought this 3x magnifier to go behind the SPARC2 red dot and I'm really happy with the combo. I have had this magnifier mounted behind the SPARC2 for 2 years now on my Colt LE6920 and have put thousands of round down range. It has excellent clarity and works perfect behind the SPARC2 red dot. I like the ability to fold it out of the way for closer shots using only 1 hand in a quick easy motion. You wouldn't think 3x magnification would make much of a difference but man what a difference at 100yrds. I was able to consistently get 1in groups at 100yrds with this magnifier and the SPARC2 red dot. I wouldn't hesitate to by another of these to put on another rifle or shotgun behind a red dot, it really does make a big difference when reaching out to 100yrds.

Rated 4 out of 5 by from Great magnifier with a lousy mount. A good affordable magnifier that does just what it needs to. The only catch is that the flip away mount is a lousy design. The way it comes out of the box when you flip it out it's basically sitting right in your chest when you have it on a sling. I actually turned amount around backwards so it flips away from your body for right-handed shooter. It works fine but honestly still feels a little bit bulky with the big old button mechanism. But other than that minor complaint, it does what it needs to just fine. I have it on the extra spacer so it lines up perfect with the sight on my EOTech.

Rated 5 out of 5 by from Duty grade magnifier Civilian LEO here and I have been running this magnifier on my BCM duty rifle for 5 years now. Numerous classes and real world duty applications, this magnifier has been a game changer in terms of having the 3X power to engage targets at longer distance. In LEO line of work, PID of target is paramount and leaves no room for error. This magnifier allows the shooter to gain better feedback on targets during engagements at longer ranges. Clarity of glass is superb and the mount lines up perfectly in co-witnessing the optic to the magnifier. Able to take the punishment and use of riding in the back of my patrol car and thousands of rounds expended with no degradation of performance. The operating lever is distinct and easy to engage and disengage. Great quality and performance.
