I Tested And Reviewed The Sig Sauer Romeo 5 Red Dot Sight In 2024

If you’re looking for a reliable red dot sight that is both durable and affordable, let me introduce the Sig Sauer Romeo 5. I tested it rigorously, and can vouch for its first-rate performance.

Sig Sauer Romeo 5 1x20mm Compact 2 MOA Red Dot Sight

Highlight: Amazing fog-proof and flawless waterproof build.

Helpful review: The factory-sealed box is quite a presentation piece. The kit includes everything you need to mount the optic and turn it on: the Allen wrench, a couple of batteries in case one wears out or is just a bad one from the factory, a cleaning cloth, two mounts to make sure it fits everything, a lens cap, and finally, the instruction manual.
When you first unbox the Sig Sauer Romeo 5 red dot, you need to read the instruction manual/sheet. These red dots work and look the same, but some of the particulars are different. The Romeo 5 has different things or functions, so you must know about them upfront.
Like most red dot optics, the Sig Romeo 5 has auto-off and "shake Awake" functions. After two minutes of non-movement, the optic will shut off. That means the gun has to sit still and not move around. This is an excellent feature for nightstand guns but put it on a four-wheeler, and that sight will remain on until you put the gun in the safe. That is not a big deal or a deal breaker; all the shake-awake sights will do the same thing. The only issue with the movement on function is it will cause some unnecessary battery drain. To "fix" this battery drain, you can turn off the sight completely; as the manual says, press either illumination button for more than one second, and it will turn off.
Some new owners have reported that the red dot does not work from the start; most of the time, that is due to the red dot being turned down so low that no one can see it. The easy fix is to push the + button until it is bright enough to see in your lighting conditions.
Another issue is the sticky tape adhesive left behind after removing and installing the battery. The residue is clear and easy to miss, so use your finger to ensure the contacts are clean. The Romeo that I have did precisely this: the battery manufacturer must have used the box sealer adhesive on these pull tabs; that is a pain to deal with.
I have heard folks complaining about the Romeo at the range that the light will shut off when adjusting the brightness; the owner's manual will tell you that the brightness levels are clicked, not a constant press. If you hold the buttons down to adjust the brightness, the LED will turn off, just like it should; this is a training issue.
Also, a good note is if the optic is shut off to conserve the battery, it is all the way off. The movement On feature will not work until the buttons are pushed to turn the light on, and the brightness must be reestablished. The bottom line is that the Sig Sauer Romeo 5 will do exactly what you tell it to do; even if you did not mean to tell it to turn off, it will if you hold the adjustment buttons; again, this is a training issue.
SUMMARY:
I am writing this review as a guy approaching old geezerhood; this Romeo 5 is mounted on my AR platform rifle. The sight responds well, exactly as promised by the owner's manual. The mounts worked perfectly, the included tools are right on the money, and the extra battery is excellent, especially if your gun has a place to stash them both. Yes, this tiny optic has turrets about the size of a pencil eraser. You can find it in the Google archives if you don't know what a pencil eraser is. The turret adjustments are very nice and handy when getting this sighted in at the range. The size of this optic is great if you want a low-profile and lightweight red dot. This sight will not replace or even compete with a low-powered scope; it is not supposed to compete in that market. — Noah O. Thompson
