In terms of weight, I was surprised by how LIGHT the Sig Romeo 5 was. It almost felt like it was made of plastic.

In my opinion, it’s comparable in looks to an Aimpoint Micro.

It features a 2 MOA dot reticle and small-size turrets that adjust 0.5 MOA per click.

The clean edge profile also helps with the great field of view and maximizes my situational awareness.

Aftermarket mount options can work on the Sig Romeo 5, as it has the same dimensions as an Aimpoint Micro.

Here are some of the pros and cons of the Sig Romeo 5.

The Sig Romeo 7 is the older brother of the Sig Romeo 5. It’s designed similarly to Aimpoint CompM4 optics.

It also has the same great field of view that the Sig Romeo 5 has, although there is a bit more obstruction around the edges.

It has a brightness adjustment for the red dot sights, which I can turn easily.

The mount on the Sig Romeo 7 is a bit different than on the Romeo 5, as it’s bigger.

However, I found that a mount that can work on the Aimpoint CompM4 will also work on the Romeo 7.

You can switch mounts with the Aimpoint CompM4; just make sure to check and read the instructions before buying.

The Romeo 7 and the Romeo 5 have CNC machined extrusions to prevent accidental movement on the optics turrets.

The MOTAC system of the 5 and 7 saves battery by turning off the reticle when not in use. It also turns on when it detects movement, which is handy!

If you’re like me who always forgets to turn their sight off, you will be forever grateful for this feature.

Before you buy the Sig Romeo 7, consider these pros and cons.

Sig Sauer Romeo 5 vs. 7: A Side-By-Side Comparison

Now it’s time to check out the difference between the battery, lens quality, and reticle of the Sig Sauer Romeo 5 and the Sig Sauer Romeo 7.

Battery Life

Both Sig Sauer Romeo optics are rated for 40,000 hours of battery. You’ll probably only swap them out after a few years.

The battery-saving technology on both scopes works to detect if the scope is being moved.

I found it a bit tricky when using it as a truck gun on vehicles because it will always stay on, negating the battery-saving feature.

However, the Sig Sauer Romeo 7 can save more battery than the Romeo 5 by lowering the brightness of the red dot.

The Sig Sauer Romeo 5 can’t do this, as it has no adjustment option.

Winner: Sig Sauer Romeo 7

Lens Quality

While both Sig Sauer Romeo optics have lens tint, I’ve never really found them distracting and they don’t take away from the view of the target.

Additionally, the great field of view the lens has is very convenient for close-quarters engagements.

I can turn quickly, aim in, and my eyes can find the target easily!

The Romeo 5 is similar to the Aimpoint Micro in that they’re both light and similar in size, saving time when trying to turn and aim at the target.

However, the Sig Sauer Romeo 7 has thicker turrets and brightness adjustment mechanisms, similar to the Aimpoint CompM4.

You might feel a bit distracted, making your eyes work harder.

This is especially obvious when using it on vehicles, like a truck gun. Whether you can accept this means you have different priorities on your rifle scope.

The only reason why Romeo 7 is slightly worse in the field of view is that it has an adjustable brightness, which I’ll talk about in the next section.

Winner: Sig Sauer Romeo 5

Reticle

The reticles on both are the same, as they’re EXCELLENT for keeping on target, like other Sig scopes on the market.

However, the Romeo 7 has an adjustable brightness on the red dot, which helps change conditions.

The Romeo 5 doesn’t have this, but it can be better if you need a great field of view that doesn’t feel restricted by the adjustment mechanism.

This category is a toss-up between both Sig Romeo optics.

Frequently Asked Questions

After discovering more about both Sig optics, you might still have questions about them versus other optics or how to use them.

I’ve answered the most commonly asked questions below.

What is the Difference Between Romeo MSR and Romeo 5?

The Romeo MSR doesn’t have the MOTAC motion sensing technology that the Romeo 5 has.

It’s only rated for 20,000 hours compared to the over 40,000 on the Romeo 5. You’ll have to swap the batteries a lot less on the 5 than the MSR.

Does Sig Romeo 5 Have Shake Awake?

Yes!

The Romeo 5 has Shake Awake like other red dots on the market, which is called the MOTAC system on a Sig optic that supports it.

What Range Are Red Dot Sights Good for?

These sights are usually good for up to 100 yards because they only have a 1x magnification/zoom level.

However, if you want to shoot farther, you must get a magnifier for your optic. This thing will work on most red dots.

Please read the product instructions to see how much heavier it may get by adding the magnifier.

Final Verdict: Which One Should I Choose?

I personally think you could go with either one to buy!

The Romeo 7 and Romeo 5 are excellent choices if you want a red dot optic for close-range use. People will love the compact size of both the Romeo 5 and 7.

• Pick the Romeo 5 if you want a smaller size than the 7, and a wider field of view is amazing on this scope.
• Pick the Romeo 7 if you want something similar to an Aimpoint COMP4, and has adjustable brightness for the reticle.
