What makes this magnifier a game-changer is its ability to provide a four times better view of your target, particularly useful in varying light conditions like daylight or the low light of dusk and dawn. This feature is crucial for accurately identifying your target, ensuring a clear shot.

Another significant aspect is its robust construction. The side flip mechanism is solidly built, ensuring that it stays steady without any wobble. This stability is essential for maintaining accuracy in your shots.

Choosing the Vortex Micro 3X magnifier for your Sig Romeo 5 is a smart decision for several reasons. Firstly, it offers improved eye relief, which means you can position your eye further from the eyepiece while still seeing the full field of view. This feature enhances comfort and ease of use.

Additionally, the Vortex Micro 3X provides a 28% larger field of view compared to standard magnifiers. This wider view is particularly beneficial when tracking moving targets or scanning wide areas.

The Holosun HM3X magnifier stands out as HoloSun's latest offering, delivering top-notch value. Its quick transition feature allows users to effortlessly switch from 3X magnification to a 1X red dot. 

This is by far the most rugged 3X magnifier I have felt when I first received it in the package. I mean the mount is sturdy and stiff, and the glass quality is superb.

Aimpoint 3X-C - Lightest Weight

  • Magnification 3x
  • Eye Relief 2.2 inches
  • Angular Field of View 6 degrees
  • Length 4 inches
  • Weight 7.8 oz

The Aimpoint 3X C is the more affordable substitute for the military-grade Aimpoint 3X magnifier for those on a budget. When comparing the two at the local gun shop, I've noticed that they are the same, and I have decided to go with the commercial model for a much cheaper price.

The magnifier can be mounted on a 30mm mount, and there are plenty of options to choose from including Scalarworks and Unity Tactical if you want to go expensive. 

This adaptability makes it a practical option for various applications, whether you're into hunting, target shooting, or other outdoor activities. Its ability to fit into different setups makes it a valuable and versatile tool for anyone interested in firearm optics.

  • Very clean glass
  • Much more affordable than the mil spec model
  • Works with most 30mm ring mounts
  • High quality coating
  • Wide FOV


  • Not mil spec to lower the price point
  • Magnification 3x
  • Objective Lens Diameter 24 mm
  • Eye Relief 2.64 inches
  • Linear Field of View 37.9 feet @ 100 yds
  • Weight 7.9 oz

The Primary Arms 3X magnifier offers an affordable solution for those needing a magnifier. Once I purchased it, I realize I need to buy a separate 30mm mount, which is a hassle.

Its latest GEN IV model boasts an improved eye relief distance of 2.64 inches, longer than the 2.2 inches in the Aimpoint 3X, allowing for greater head movement flexibility. 

The integrated diopter in the GEN IV enhances the focus quickly, ensuring a clear target image. A durable rubber sleeve cover also protects the magnifier from scratches and impacts, making it ideal for outdoor use.

These features make the Primary Arms 3X magnifier a practical and user-friendly option in firearm optics for both beginners and experienced users.


  • Very affordable for casual shooters


  • Out of spec for some 30mm ring mounts
  • Loose diopter adjustment ring

Sig Sauer JULIET6 - Most Affordable 6X

Sig Sauer Juliet 6X magnifier
  • Magnification 6x
  • Objective Lens Diameter 24 mm
  • Eye Relief 2.3 inches
  • Angular Field of View 4 degrees
  • Length 5.4 inches
  • Weight 14.7 oz
  • QD PowerCam 90 Degree Flip Mount

The Sig Juleit6 6X magnifier is recommended for users considering if they should buy a 1-6X LPVO or stick with red dot magnifier combo. The Sig Sauer Juliet 6 offers a budget-friendly alternative to the Aimpoint 6X without compromising performance or quality. 

As far as saving money, the Sig Juliet 6X is a much better option for Positive Identification (PID) at distances beyond 300 to 400 yards. 

Another notable feature is its very rugged mount. It uses the same PowerCam 90 mount as the Sig 4X magnifier. This type of mount is important for maintaining stability and accuracy, especially in challenging outdoor conditions.


  • Very affordable 6X on the market
  • Same quality as Juliet 4


  • Very tight field of view
  • Not the same as 1-6X LPVO

Before you pick up a magnifier scope, make sure you know which mount you want.

There are fixed mounts, flip to side mounts or twist mounts.

Flip to the side mount is the most popular because you can basically tug the scope away if not needed, or flip it back when you need it.
