Sig Sauer Romeo 5 Review

The ROMEO5 is a Sig Sauer compact red dot sight that uses their proprietary MOTAC™ (Motion Activated Illumination). This system shuts down the battery when it senses inactivity for 10 minutes and will reactivate when it senses movement.

This particular model is part of the ROMEO series and is considered to be combat-ready. Well, to find out if it is combat-ready. I was asked to test it out.

Now, with over three decades of combat experience from two wars in the Middle East and countless hours of added reserve duty, I guess I have the tools to gauge the combat readiness of rifle scopes and sights.

So, let’s take a look and see what Sig Sauer has brought to the market this time.

Sig Sauer Romeo 5 Review

The ROMEO5 is a compact red dot sight that offers effortless target acquisition for both civilian and military requirements.

Since it’s a Sig Sauer it comes from a home that understands weapons as well as sights, so you like buying an engine from a car manufacturer, they know what they are doing.

To better get an understanding of the range of performance that this sight gives, I decided to break down this review into categories, and these are:

  • Optics
  • Body
  • Power
  • Performance

Optics

This model delivers a 1x aiming solution combined with an ultra-low parallax. This combination delivers a point-of-aim is point-of-impact. It also allows for the red dot to remain parallel to the bore the firearm.

This situation remains static irrespective to what your viewing angle in relation to the optical axis of the sight.

Unlimited eye-relief enables you to effortlessly acquire the aiming point and the target no matter the position of your eye behind the sight.

In two models the reticle is a 2 MOA Red-Dot that can be set with 10 illumination settings (8 daylight plus 2 NV), in one model you also get a 2 MOA Dot / 65 MOA Circle option.

The brightness levels are automated, but you can adjust them manually, the MOTAC™ (Motion Activated Illumination) powers up automatically when motion is sensed, and it turns your reticle on to the last setting it was set.

The red dot is clear, and when looking through the optics, you see a clear, crisp picture with a fine red dot slap dang in the middle.

There are three models available, so you can choose between the Romeo5 Sig Sauer SOR52001 which uses a CR2032 battery cell, the Romeo5 Sig Sauer SOR52101 that uses a single AAA battery loaded at the front of the body, and the Romeo5 Sig Sauer SOR52102 XRD which uses a single AAA battery but comes with a 2 MOA Dot / 65 MOA Circle option. Here is a table to make this easier to read:

Body

The body is a block of machined aluminum that has been anodized for a matt black finish. The mount is an M1913 Picatinny low mount riser and comes with a co-witness 1.41” riser mount.

This is a quick clip-on version, you just need to decide which one you prefer. Set your mount to whatever height is desired – low or 1.41” and off you go to the range.

The body is IPX -7 rated, which means it is waterproof, it actually happens to be shockproof and fog proof too, but that’s not a body feature more or a performance feature.

Power

The ROMEO5 comes with a single side loading CR2032 battery or a single front loading AAA battery (depends on the model you select) that gives you more than 40,000 hours of life, and this is only due to the MOTAC™ (Motion Activated Illumination).

The battery is easy to access, you just need to unscrew the opening on the right side of the body and replace it, but with so many hours of fun to be had, I doubt you will be replacing it during the scopes average lifespan, consider that 40,000 hours is the equivalent of 4.8 years!

The power source allows you to set up to 10 daytime brightness levels and 2-night vision levels, consider that the system is automatic when turned on, so it adjusts the brightness to the ambient light.

You can turn this feature to manual if you prefer to control the light levels.

Performance

This is a simple to operate a device, and that is perfect for both civilian and combat purposes. Since this is a Sig Sauer, you can be sure it has been tested well before it was released.

This model is exceptional and is tuned well to the needs of a hunter, a protector, and a defender. This means it will deliver easy to use performance in all conditions and withstands the knocks and bangs of intense combat.

The knobs are easy to move, the sight is well secured on its mount, and it withstands the rigors of intense shooting on any number of weapon types.

I took this model out on a standard AR-15 model and went to the range. Now for most the range is a long channel of nothing with a target at the end. My range is southern Iraq where anything can pop-up at any time.

As usual, in the summer, the Iraqi desert is hot, dirty, inhospitable and full of flies, a few goats, and the occasional dog.

I went to a secluded, deserted bombed-out village location and together with a couple of friends went about testing our reflexes and our various weapons and accessories.

Let’s start off by saying that at 50, 100 and 200 yards, this optic provided me with admirable acquisition solutions.

Not only was I able to acquire the target quickly and effortlessly, but I was also able to fire of round after round with as much precision as I am capable of delivering.

The targets we set up in various locations were all man-sized, and we put them in certain locations where lighting would differ, making some harder targets to acquire.

I have to state that the MOTAC works, although it is not just proprietary to Sig Sauer since a few other makers have it too, such as Holosun and Primary Arms, with this in mind, the MOTAC delivered as it claimed, and when I took a rest, so did my sight.

When I pulled my rifle back up, my sight was already lit and ready.

After a few days and 500 rounds later, the point of impact has not shifted, and the mount is as secure as it was when I initially tightened it on.

To be honest, I dropped my rifle a couple of times to see how it affected the sight, I also banged into walls, dove into ditches, dragged it through some murky water and it still performed.

Conclusions

The ROMEO5 is a compact combat-ready device that comes with an absolute co-witness with iron sights. It maintains its performance throughout the harshest of conditions. The red dot is adjustable using the push-button system, and this works fine for me.

It is a 1x model, so if you are looking for higher magnification, either add a 3x magnifier aptly named Juliet to attach to it or buy another model.

The tube and design are classic, and it comes with a “Sig M 400 tread” version as well.

The bottom line is that this is a simple, basic and easy to use site that provides exactly what you hoped it would.

Its chunky mount can shy away from some users that prefer to have lighter options, but consider the fact that this model comes with a mount that is both removable and that it is also compatible with an Aimpoint T2 style mount.

So what are the overall pros of this optic:

  • High-grade clear lenses
  • Bright dot clarity
  • MOTAC
  • Affordable
  • Durable but lightweight

Little known fact: this model is manufactured in the same Chinese location as the Holosun, so you get great quality knowing its made in the same place. However, there are differences between the two, and this is a review of the Sig Sauer, so let’s leave it at that.
