Sig Romeo Zero Review – Best Budget MRDS
Sig has been making optics for a good amount of time now and they even have military contracts with some of them.
The Sig Romeo Zero is their entry-level budget red dot designed to be mounted on pistols.
This optic is extremely compact and lightweight. It’s not the most durable optic but for the price, it’s hard to beat.

First Impressions
When I first pulled the Sig Romeo Zero out of the box I couldn’t believe just how light it was.
The size and weight make it a solid contender for a concealed carry pistol and even a sub-compact pistol.
You will not even notice this red dot on your pistol.
Because of the polymer and weight, I worried about the durability of the Sig Romeo Zero.
What’s In the Box?
Here is everything you get in the box with the Sig Romeo Zero:

Reticle
There are two different reticles, 3 MOA and 6 MOA. This is personal preference, I personally like a larger dot on concealed carry guns.
The Romeo Zero has 8 different brightness settings.
I never had any issue seeing the dot, even in direct sunlight.
The dot is very crisp and what you would expect on a red dot sight.
It was pretty close to zero from the factory so I didn’t take long to sight it in. I did a standard 10-yard zero for a concealed carry gun.
I used the included Allen key to adjust the windage and elevation and it was easy and simple to do.
The LED emitter was protected by the housing and design, but still exposed to the elements.
Size
The Sig Romeo Zero has a compact design and its one of the smallest red dots that is usable.
It is also lightweight and you will not even notice a weight difference when carrying it on a pistol.
This red dot only ways 0.5 ounces.
When aiming your pistol it feels natural and the optic draws your eye in with the perfect sized window.
Finding a holster for this optic setup won’t be an issue because of it’s small design.
Construction
The Sig Romeo Zero is mostly made of polymer which is concerning for such a high-stress component.
The window is secured using aluminum and because of the price, it is not as strong as other more expensive micro red dots.
The glass is scratch-resistant and is slightly magnified so not a true 1x.
I’ve noticed the glass does scratch fairly easily and would still take extra caution when handling it.
The battery storage compartment is under the optic so this can be annoying when changing the battery.
You will have to remove the optic completely and then re-zero.
Overall you are getting a decently built red dot.
Battery
One of the best features of the Sig Romeo Zero is the battery life. 20,000 hr runtime is what is advertised.
This will of course depend on what conditions the optic is stored in and also what brightness setting you have on.
You can reasonably expect at least a couple of years without having to change the battery.
Replacing the battery is simple with the right tools and Sig includes the Allen Key in the box.
The long battery life is one of the only categories where the Sig Romeo Zero outperforms its competitors in this price range.
User Friendly
The Sig Romeo Zero is compatible with the following mounting systems:
- Direct mount to ROMEOZero
- Shield RMS-c footprint
- J-Point footprint
The motion-activated feature is awesome and works great.
I really like this style for pistol red dots especially intended for concealed carry.
The buttons are small but still accessible and are easy enough to adjust.
Replacing the battery is simple but could implement a better design.
This optic is simple and works great for concealed carry.
It has all the features you want and expect in a pistol red dot for a reasonable price.

Final Thoughts
This Sig Sauer Romeo red dot optic is the right size and right price for concealed carry, especially if you are on a budget.
If you are looking to get a micro red dot sight for the first time the Sig Romeo Zero is a good entry-level choice.
If you want to consider some other similar micro red dots I have posts on my Holosun 507K Review and my Holosun 507C Review.
Both of those are a better purchase in my opinion, but are more expensive.
