Why the Sig Sauer is My Top Pick

sig sauer romeo 5 review unboxingWhat immediately stood out to me was the lightweight design of this red dot. This is beneficial because you can take it everywhere where you go with much ease. It’s  enclosed for extra protection and it’s quite tough.

It is crafted from a durable aircraft grade aluminum, which makes it withstand the test of times.

Unlike other sights, this one has a waterproof body, it’s also shock and fog-proof. This means you can take it to extreme conditions without fearing malfunction. I have tested it in 3 feet (1 meter) deep water and it doesn’t leak.

It’s interesting to see the Motion Activated Illumination (MOTAC) which is the feature that stood out to me when it comes to performance. The MOTAC is designed to boosts the battery life by shutting down the system when not in use while at the same time activating the system at the slightest sensation of vibration or movement. In short: your sight will be activated once you move your gun.

And another thing about the battery is side loading which means you can quickly replace the battery without removing the sight from the firearm.

It includes a high 1.41-inch riser mount and standard lowered mount. It’s designed to mount on any pica tiny rail system.

The Sig Sauer Romeo 5 is backed by a lifetime warranty covering any defects with the sight. What this means is that your optic is guaranteed forever.

It gets better with the realization of the highly efficient, ultra-wide broadband, anti-reflection lens coatings that reduce surface reflections in low light levels across the visible spectrum. The advantage here is that you will it ensure maximum light transmission for a crisp clear image.

The objective lens is another selling point. It’s 20mm, which makes it easy to see the image. On top of this, this objective lens is best for use with two eyes opened shooting style.

This sight is parallax free which means the point of aim and the point of impact will remain the same. You will also take advantage of the unlimited eye relief this Sight offers, therefore, you can acquire the right aiming point and target no matter the position of your eye behind the sight.

Another cool thing about the red dot reticle is the 10 different settings with 8 of these being for daylight and two of them designed for night vision.


  • It is night vision compatible
  • Comes with 2 mounts
  • The MOTAC preserves the battery life
  • Dependable waterproof, shock and fog proof performance
  • Fully multi-coated lens for crisp clear picture
  • Easy to adjust settings
  • Extremely small and lightweight
  • Auto-on and auto shut-off function 

drawbacks but not deal breakers

  • The objective lens could be larger 

What to consider when buying yourself a red dot sight?

Buying the best red dot sight is a serious decision that requires great attention. Of course, the last thing you want is a sight that cannot give you a good aiming and target position and don’t perform to your expectations. So here is a quick overview of the things you need to consider;

Reticle type and pattern: all reticles will be illuminated in low light conditions but it is not a must for them to be red or simple. Besides, they can range from simple dots to multiple aiming points. So just understand the type of reticule, you want for your rifle in order to match your intended purpose.

Battery and power: battery power illuminates the reticle in most red dot devices. So the battery life is an important consideration. Choose a sight with enhanced battery power to enhance your confidence. This will allow you to spend many hours outside before needing to replace or recharge.

Weight: no matter how you want to use your scope the weight of the red dot sight can make all the difference. Weight affects the accuracy of your shot so you need a sight whose weight will not diminish the accuracy of your rifle.

Dot size: you need a dot that is visible. A small dot will make it hard to for you to pick up the target quickly. Nevertheless, this does not mean you choose an overly large dot size because it is likely to obscure the target if you are shooting at greater distances.

Durability: this ensures you get the value of your money. Check the construction and warranties to ensure it is in good condition.

My final thoughts

This Sig sauer Romeo 5 review establishes that this is one of the best red dots on the market in terms of performance and under low light conditions. It holds zero very well. It’s ratio price/quality is better than competing products of other companies, that’s why it’s such a popular choice.

This red dot is reliable, strong, waterproof and great quality. It was a no-brainer for me.

  1. I can’t seem to attach my Romeo 4 to my scorpion pistol. It’s sits too high; I want to use it as well on my sig 556 pistol. Is it designed for pistols? If so, am I mounted it incorrectly? thank you

    • It will work fine but if you get a lower mount than what it comes with and have 2″ of available space to mount it on it would be more comfortable.

  2. My new Romeo 5 fit perfect on my Scorpion Evo using the higher mount. Went to the indoor range tonight, fired a few rounds and it was zeroed. I love this red dot. Quick sight acquisition with the small dot (2 moa) and follow up shots. It is easier to look through the Romeo 5 with my not so perfect vision than it is my $400 EOTech. I think it’s time to sell my EOTech and buy another Romeo 5. Thanks Sig.
