Very Clear Magnification

I've used this magnifier with a red dot out to 400 yards and had no problem with being able to see the target well and was able to have a rather precise holdover. I've used it while others are using LPVO and other scopes and have been just as successful in hits as them. Glass is very clear, the flip is smooth and it doesn't throw off the weight of the rifle. The mount is very easy, just make sure it is fully tightened down.

Glad I grabbed it

Great magnifier for the price! I paired it with my Vortex Strikefire 2 red dot. Extremely easy to install and just as easy to use! Highly recommended if you are looking for a solid 3X at a great price.

I love the value that Vortex consistently brings. They have great products and at a great price point. The lifetime warranty to back it up is a HUGE bonus. Keep innovation and bringing great products to market. Vortex is amazing.

Great magnifier.

Use this on a ACR with eotech 512. This lines up with both the 512 and xps2 out of the box, no riser was necessary. Great clarity and easy to use. Eye box and eye relief are standard for a magnifier. This is a good recreational and sport magnifier. I'm not sure how rugged it is, but that really doesn't matter because vortex warranty is unparalleled.

Exceptional addition!

Simple, well built, fantastic quality and easy to install. This takes the red dot game to the next level! Added this to my AR15 and it fit perfectly. The "shim" (riser) that came with the device was the perfect lift I needed to have it align perfectly with my current Vortex red dot. 10/10 would recommend!

Awesome for the price

Really easy to use and mount. Clear glass, and works really well with the Crossfire on my AR15. Only thing that I kinda have an issue with is the eye relieve is pretty short, so it forces me to hold the gun at a slightly awkward angle. Swapped out the buttstock with an adjustable one and things are great

Bang for buck is amazing

I bought mine back in 2020 right before I went to Afghanistan. I really love this thing. It took me a bit to get used to as with any new piece of gear, but 4 years later I still have it and still love it. Glass is nice and clear, mounting is easy. My only issue is there's some play in the flip mount that developed after a few months but it doesn't make it less effective. If only the army would get better red dot sights or my unit would allow personal optics. All and all this thing is a beast.

Magnifier - worth it.

Quality product. Ease of operation. Use it on my .223 and my .17 hmr for pig and varmint hunting. I have no issues with this product. Everything worked beyond my expectations and lines up with other optics on various rifles of various calibers. This product is easy for any level of shoot or hunter to use in any shooting application. Good quality and take recoil well up to a .30 cal. Y'all need to buy this and add to your collection.

Great addition

This lives behind a red dot on a hinting rig. It allows me to better take an ethical shot at extended distance. it was instrumental in taking the top off of a does heart not that long ago. The flip option is great as well amd is fast, solid and positive. Once in either position it is NOT moving until you intend it to.

Great quality product!

I bought this magnifier to use with the StrikeFire II. It has been a great addition to the optic setup on my AR. Not only does it create a clear magnified sight picture, it is just as resilient as any Vortex product. It can take some beating. Vortex optics never disappoints.

This guy is incredibly clear. The price is great and the warranty is great. Only thing I have to say about it that is negative is that it is not easy to switch which side it folds to. Folding to the left is what I prefer so it worked out for me.

Compromised and Saved a Bit of Money

It's a good little magnifier, and there's nothing wrong with it; however, they also make a newer, shorter version of this that doesn't require you to push a button to move the magnifier into place. It's not as good, not as convenient, but when I bought mine... it allowed me to save $100. I bought one of each Vortex magnifier, and I was satisfied with both.

Excellent optic for the price.

Excellent, clear optic fits great behind the strikefire 2 red dot when using the spacer plate and longer screws. Used this to magnify my rifle for hunting using the red dot sight. Quick and quiet flip system. Worst part was having to sight it again after moving the red dot. Everything else was great.

Better than expected

Reading reviews people said that unit flips out to the left, which would make using both eyes an issue. After receiving the item I found it was able to flip left or right. This make this unit highly functional. Love the clarity. Perfect with the red dot unit. Good for beginners or expert. Some people stated that the 2 moa would be better but I find the 4 moa to be perfectly functional

Love these magnifiers

Our suppressor company runs a lot of test guns and, after running one of these behind a Vortex holographic soft, I ordered 2 more for a couple more of our AR platforms. Excellent performance, and we're pretty hard on our test rigs. Also, customer support is excellent All experience levels will like this product

Vortex optic 3x magnifier

The glass is great on this. When training at the range, it is easy to use and maneuver with the mount that comes with it. It really levels up your ability to sight in your rifle as well as get a clearer look at what your aiming at. I haven't had any issues with it yet but as I continue to put it through the ringer I will update my review. If you're looking for a magnifier, this is a great option.

Battle Tested

By D1-2B

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...

Duty grade magnifier

By Robert_82

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 perf...
