“There is no denying good vision is a must to become a good shooter. That doesn’t mean you have to only rely on your pure eyesight to hit the target. There are many upgrades that you can do to your gun for a better look at the target. The first thing that comes to our mind is optics.”

Vortex Optics VMX-3T Magnifier with Built-in Flip Mount , Black, Size 37-40

If you are a proud owner of a tactical rifle, Vortex Optics VMX-3T Magnifier is the optic that you should try right now with your gun. Typically tactical rifles have a small shooting range. But that doesn’t mean you can clearly see targets further away from you with the naked eye.

Does Vortex Optics VMX-3T Magnifier Require a Red Dot Sight System?

Red dot sight systems are a popular upgrade among many tactical rifle owners. It is a non-magnifying optic upgrade on rifles that require aiming. LED is used to illuminate a point of aim on the eyepiece. The red dot is ideal for close-range shooting on a moving target.

The main disadvantage of red dot sight is you can not use it on a target further away from you. Because there is no magnification on it. That’s when Vortex Optics VMX-3T Magnifier comes in. Simply, this magnifier can magnify your red dot sight or quickly get out of the way and let you use the red dot sight alone.

How Much Magnification does VMX-3T Magnifier Give Us?

This magnifier will enhance your viewing distance by three times. As per the manufacturer, the field of view of this VMX-3T is marked as 100 yards (38.2 ft).

What are the Dimensions of Vortex Optics VMX-3T Magnifier?

  • Length of the Magnifier – 4.3inch (11cm)

Considering this length, I can safely say that there is plenty of room for you to mount both red dot sight and magnifier on many modern tactical rifles. We are used to keeping some fair distance between red dot sight and our eyes. VMX-3T Magnifier fits perfectly into that vacant space with these dimensions.

Does Vortex Optics VMX-3T Magnifier Weigh a Lot?

Adding more weight to your gear will always limit your mobility. So any upgrade that we do to our rifle should be with minimum weight.

  • Weight of VMX-3T Magnifier – 11.9 oz (337g)

This is not a weight that pro shooters will concern much about. So if you had any doubt about losing your mobility by adding the new magnifier, I hope it’s not there anymore.

How do I Attach the VMX-3T Magnifier to the Mount?

Using the two screws included in the package, you have to attach the magnifier to the flip mount. The limit for tightening is mentioned as 20 in/lbs. Make sure the Ocular lens and the release button is facing towards the shooter when attaching the two.

One noticeable advantage here is whether you are left-handed or right-handed, you can attach them according to your preference.

How to Fix the Mount Attached VMX-3T Magnifier to Your Gun?

This is far easier than attaching the magnifier to the mount. All you have to do is place the magnifier on the top gun rail and tighten the screw. It looks pretty solid when you use fingers to tighten the screw, but a wrench is recommended.

What are the Mounting Options that Come with VMX-3T Magnifier?

You can find two mounting options available with this optic.

  • Absolute Co-Witness Height with Flip Mount

The first option is the plainer option. You can position the VMX-3T on the rail and tighten the screw. When you do that height from base to center of the optic will be 37mm. This will put the dot height at a center sight picture when co-witnessed with standard AR-15 iron sights.

  • Lower 1/3 Co-Witness Height with Flip Mount and Shim Plate

When you are purchasing a VMX-3T magnifier, you will receive a shim plate. When You use this at the bottom of the base, the height from rail surface to center of the optic will be 40mm. This puts the dot height at a lower 1/3 sight picture when co-witnessed with standard AR-15 iron sights.

How to Recenter the Red Dot Image on VMX-3T Magnifier?

When you finally attach your VMX-3T Magnifier to your firearm, you will find that the red dot is not positioned right in the middle of your view. This does not mean your aim is not accurate. Because the magnifier only magnifies the view from your red dot sight.

But you will prefer the red dot to appear at the center of your view. Naturally, that’s where our eye will look for the red dot when the target is within your sight. Not to worry, Vortex has given you the option to adjust that as well.

You can find two screws on the magnifier, one on top and one on the side. Using these two, you can center the red dot on your optic. Try not to force the screw if you feel any resistance. That will only mean that end-of-travel.

I would like to highlight this again. Perfectly centering is not required here because that will not affect the accuracy by any means.

How to Adjust the Focus on VMX-3T Magnifier?

If you are receiving blurry images, try the focus knob near the Ocular lens to get sharper images. You can turn the dial clockwise or counter-clockwise for this.

How to Use the Flip Mount?

This is the main highlight of this optic. You can simply push on the release button and flip it off to the side when you don’t need it. Once you flip it until you press the release button magnifier will not move to obstruct your view.

Is VMX-3T Magnifier Waterproof?

Yes, it’s waterproof due to the rubber O rings used in every joint. Besides that, this unit is nitrogen purged for making it fog proof. There is nothing for you to worry about how adverse the weather condition is VMX-3T Magnifier is ready for anything.


Having a better vision while using your firearm can only mean better performance as a shooter. Many close-range shooters use red dot sight for their assist. But when a target moves a bit further away, you might need a magnifier to take a better shot.

That’s where Vortex Optics VMX-3T Magnifier becomes useful to you. Because you can flip the magnifier instantly out of your way, it will not bother you when you need to switch back to close range again. Do you want to be unstoppable with this magnifier, the choice is yours. Give EHomeSecurityCamera.com A Try? Best Home Security Cameras Reviews.
