Red dot sight magnifiers are tactical optics developed to increase the range of use of the popular red dot sights. 

On the market, there are dozens of models of red dot sight magnifiers and one that stands out is, without a doubt, the Vortex Magnifier VMX-3T.

Vortex Optics is a widely renowned manufacturer of sports and tactical optics, its VMX-3T model being considered by many the best Vortex magnifier on the market.

Let’s discuss its characteristics in detail.

Vortex VMX-3T Magnifier With Red Dot

Vortex Magnifier VMX-3T Design

Those who are already familiar with the Vortex’s optics know that the manufacturer is famous for creating sports and military optical instruments characterized by a simple yet functional design. 

The VMX-3T respects the brand’s reputation, its design being sleek, extremely simple and highly functional.

This optical instrument is designed to provide field magnification on demand, for this purpose being provided with a flip mount that allows the user to lock the magnifier in place or simply put it aside when magnification is not needed.

The VMX-3T is made of anodized machined aluminum, boasting a robust, almost indestructible structure that protects the delicate and highly performing interior. 

Robust, however, doesn’t mean heavy or bulky.

In fact, from an aesthetic point of view, this model can easily be considered the top Vortex magnifier on the market. 

The instrument has a sleek silhouette that inspires masculinity, the round body being highlighted by an octagonal element. 

The satin matte black finish enhances its aesthetics.

VMX-3T’s dimensions are thought for convenience. 

Weighing only 11.9 oz., this magnifier will not add a lot of weight to your gear. 

The instrument is also fairly compact; the magnifier measures 4.3 inches in length and it has a diameter of 1.36 inches.

Vortex Magnifier VMX-3T Features

Some of the defining features:

On-Demand Magnification

Probably the most appreciated feature of the Vortex Magnifier VMX-3T is the possibility to simply flip the instrument when magnification is not required, without forcing users to take the magnifier off the rifle. 

According to us, and also according to many other users, this feature is extremely useful, since many of those who use a red dot sight usually use it without magnification.

This magnifier comes with a convenient flip mount, the instrument flipping to the left when its use is unnecessary.

3X Magnification Power

Red dot sights are optics built for short range shooting and a magnifier should only help the user to better identify the target at distances larger than 100 yards. 

However, the purpose of a magnifier is not that of transforming a red dot into a long-range scope.

The 3X magnification power of the VMX-3T is perfect, allowing the users to see the details of a target and identify the elements behind it, for an optimal aiming and shooting, maintaining in the same time the characteristics specific to the red dots, namely the incredible accuracy of the visual.

High-Quality Lens

Vortex’s optics are famous for their reliable lens systems, the VMX-3T providing incredibly clear and bright images. 

To guarantee the optimal light flow, the lens system is fully multicoated. 

This feature increases the light transmission, improving the quality of the images.

O-Ring Sealed

To make this instrument waterproof, the manufacturer built the magnifier with O-ring seals that prevent dust, moisture, and debris from getting into the tube. 

Thanks to this feature, this instrument provides the same performance in all environments.

Nitrogen Purged

Besides the anti-water, dust and debris characteristics, this instrument is also fog-proof. 

For this purpose, the manufacturer filled the tube of the instrument with nitrogen, the gas providing supreme reliability to the lens system.

Great Optical Specifications

An extremely important feature is the optical performance of this instrument. 

The VMX-3T boasts a 30mm objective lens that ensures an incredibly wide field of view and a great eye relief. 

If you are interested in numbers, the eye relief is 2.2 inches, while the field of view is 38.2 feet at 100 yards.

Multi-Height Mount System

The manufacturer equipped this magnifier with a spacer shim designed to allow the use of the instrument at two different heights. 

You will be able to choose between a lower, 1/3 co-witness height (40mm) and an absolute co-witness height of 37mm.

Strengths & Weaknesses

It is easy to tell that the Vortex Magnifier VMX-3T has excellent specifications and features, but does it have any weaknesses? 

Let’s have a look at its main pros and cons.
