Vortex Micro 3X Magnifier Review

As light bending technology for manufacturing scopes advances, smaller size magnifier scopes are available without compromising magnification.

This is a Vortex Micro 3X magnifier review guide, and we will take a look at this compact size red dot magnifier from all angles, then take it to the range to hit some steel targets at 100 - 200 yards to extend our 1X red dot sight capability.

Let's check it out

Unboxing

Vortex Optics ships the Micro 3X in a very neatly packed box that doesn't feel cheap. Inside the box you get:

Initial Impression

This thing is rock solid.

When you pick this up it feels rigid AF, and the spring tension on the side flip mount feels rock solid enough to go on a carbine.

The package comes with a riser plate for raising the scope height for better cheek weld or leave it as is based on the ergonomics of your rifle.

Definitely not a low quality product!

So far so good, now let's look through the glass and mount it behind a red dot.

Main Application

Mid - Long Range

CQB

Improved Zero

The Vortex Micro 3X magnifier scope supercharges the capability of a 1X holographic or reflex red dot sight to hit mid and long range targets.

Shooters can transition between 1X and 3X easily while staying compact.

Magnification & Glass Quality

The 3X magnification is a decent for positive target identification, and it's the standard magnification level

Build Quality

Works with EOTech, Aimpoint, Trijicon, Holosun and many more!

The product is labeled "Made In China". At this point many products are made overseas and the product we get is definitely rock solid, and I couldn't tell the difference among other high end products.

The construction of the Vortex Micro 3X is rock solid no doubt. Pick it up and it feels like a $500 optic, but it doesn't cost you that much.

The overall size is very compact for a 3X, thanks to the advancement in optics technology where you can have the same capability but in a smaller size. 

Mount

Just Rock Solid !

Just don't mount the optic too back because the QD lever might interfere with the grabbing of charging handle if there is one.

When this happens, just move the optic forward so there is room for the finger to work around the charging handle bar.

The user can flip the magnifier scope on or off to the side when transitioning between mid and CQB targets. The flip mechanism spring quality is top notch, it doesn't wobble or can be easily flipped unless applying some hand strength.

Pick one up you if this is your first time buying, you wouldn't disappoint.

Final Verdict

Pros

  • Small and compact
  • Very clear glass
  • Diaopter ring helps adjust to user's eye sight 
  • Very solid mount
  • QD lever for fast detach
  • Works with aftermarket mounts
  • Horizontal & vertical Knobs to center the reticle  

Cons

  • Hard to adjust tension screw without a proper tool

For the price this beats EOTech's G33's price point. You get a rock solid product for $299 instead of something like the Aimpoint for $700, this is a steal!
