Best Sig Romeo 5 Magnifier – [Editor’s Pick]

1. Sig Sauer SOJ41001 Juliet4 Magnifier

Whoever named the red dot Romeo and the magnifier Juliet, knew what they were doing! Juliet4 is a 4x magnifier made specifically for the Romeo series. It is also compatible with other Aimpoint optics and many different red dot sights.

Due to its Aircraft-grade CNC Aluminum construction, you will find the magnifier to be sturdy and lightweight. It has an IPX7 rating, meaning it is water resistant. Additionally, the lens of the magnifier is crafted with high-quality coatings so that it can transfer maximum light through the glasses.

However, if you want a bit more magnification power with the same specifications, you can check out the “Sig Sauer Juliet6 Red Dot Magnifier”. This one comes with 6x magnification power with similar features.

Key Features

  • Flip to the side! You can flip it to the side while not using it to access the red dot with no obstruction. When you need to shoot at range, just flip it back to the original state.
  • Easy to install: It comes with a quick detach mount that fits in M1913 Picatinny rails. You can install and remove this from your rail without any tools!
  • Filed of view! It features a 6.25-degree field of view. That’s quite wide for a magnifier!

2. Vortex Micro Magnifier w/Quick-Release Mount

This Vortex Micro 3x magnifier with Romeo 5 is another perfect set-up on your firearm for fast target acquisition. It also ticks out all the necessary features you need in a magnifier.

The variant I got here features 3x magnification. If you don’t like 3x magnification and want something longer range, then you will find a 6x variant of this.

Now, whichever version you’re buying, you’ll find the magnifier extremely lightweight and compact. It comes with a hard anodized military-grade finish and Nitrogen purging which makes it shockproof and moisture-proof at the same time.

The magnifier lens has anti-reflective coatings to transmit maximum light for a brighter target image. It has scratch-resistant coatings so that the lenses don’t get damaged in heavy impacts.

The magnifier has a Quick-Release flip mount and a riser. So, whether you want to do the Absolute Co-Witness or lower 1/3 Co-Witness, it gives you both of the options. Just use the mount riser when you want to do the lower 1/3 Co-Witness with your optic.

The only downside of this magnifier for me was the eye relief. I Would have preferred a 3-inch or larger eye relief. But the included 2.64″ eye relief is not that bad once you get used to it.

Key Features

  • No adjustment is needed! Once you install this magnifier on your rifle, you don’t need to change a single thing about it anymore. But if you find yourself with a dot misalignment, then you can use the dot-centering screw to fix the elevation of the optic.
  • Easy to mount: It comes with all the necessary mounting gears you need to install on a Picatinny rail.
  • Riser plate included: If you want to change the height for the magnifier, then you can use the stock riser plate.
