Both Sig Romeo 5 and Vortex SPARC are neck to neck when it comes to specificity. However, some minute details and adjustments will play a key role in deciding which one is better than the other. 

Optics Comparison 

Optics are a crucial part of red dot sight. It becomes extremely crucial to assess the optics before buying any dot sight. The lens clarity of Sig Romeo 5 meets the satisfactory par and is good in terms of attaining a clear picture. It does not create a greenish tinted reflection which makes it very clear for the hunter to look into the dot sight. 

The reticle is 2 MOA and the reticle color or dot color is red. Red dot color with a balanced reticle size of 2 MOA is a perfect combination to aim at any target. It is not too large to distract the viewer, or even too small to not make any difference. Sig Romeo 5 passes the test very well. 

Now, Let’s compare Vortex SPARC with Sig Romeo 5 with regards to optics. This apple doesn’t fall too far either. Vortex SPARC has similar optic fundamentals to Sig Romeo 5. It becomes a tough competitor of Sig Romeo 5 with the same specifications like 2 MOA and red reticle color.

Range and Magnification

Range and Magnification are the two virtues to look at in detail while buying a dot sight. 

Both Vortex SPARC and Sig Romeo 5 have excellent optics that are almost similar concerning magnification. Both possess 1X magnification which is quite impressive and useful. 

However, one little detail where Vortex SPARC excels is the range. Vortex SPARC is adorned with a 22mm objective lens diameter whereas the Sig Romeo 5 has a 20mm objective lens diameter. 

From these observations, we can infer that the Vortex SPARC provides a slightly enhanced range as compared to the Sig Romeo 5. 

Now that we have covered the very crucial optics section, let us move on to the other specifications which are equally important. 


While delving into the other specifications you will spot some minute differences. Needless, to say you will get many options and accompanying adjustments in both the dot sights. 

Vortex SPARC has unlimited eye relief along with 12 extensive illumination settings. This will help you to adjust your optic performance in any kind of environment and surroundings. It gives you the liberty of hunting anywhere without being held back by any limitations. 

On the other hand, Sig Romeo 5 lacks a bit as compared to Vortex SPARC. Sig Romeo 5 has the same unlimited eye relief, but it just provides 10 illumination settings. Out of 10 illumination settings, 8 are for daylight, and 2 are for night vision. Similarly, Vortex SPARC has 10 daylight settings and 2 for night vision. 

What Sig Romeo 5 lacks in illumination settings, it compensates it with other impressive features. It bears the MOTAC feature which means Motion Activated Illumination. This feature enables the dot sight to automatically turn off after 120 seconds of inactivity. 

This feature may seem simple but it reduces your need to push buttons every time you do not use your dot sight. It greatly impacts the battery life of Sig Romeo 5 by reducing unnecessary battery drainage when not in use. 

When we compare Vortex SPARC features to Sig Romeo 5 in terms of such features, the latter tips the barrel to its side with amazing features like MOTAC.

Windage Adjustment, Impact point correction, and Elevation adjustment. 

Vortex SPARC excels Sig Romeo 5 in all the three aspects above. It has 90 MOA windage adjustment, 90 MOA elevation adjustment, and 1 MOA impact correction point. Whereas, Sig Romeo 5 has ½ MOA impact correction point, 80 MOA windage adjustment, and 80 MOA elevation adjustment.  

Battery Life 

Further on digging some more specifications, we discovered that both the variants ie., Vortex SPARC and Sig Romeo 5  have decent battery longevity. Vortex SPARC has 50,000 hours on the highest settings and 700 hours on the lowest setting, which is not bad. 

The Sig Romeo 5 has 40,000 hours with no specifications about the settings. However, we assume that it is the average battery longevity in both settings. In that case, Sig Romeo 5 does not differ much from Vortex SPARC with regards to battery longevity. 

Sig Romeo 5 has a CR2032 battery and Vortex SPARC has a AAA battery. If you are a person who wants minimum hassle for battery replacement, Vortex SPARC will be your best bet.

 AAA batteries that Vortex SPARC uses are easily available in the market as compared to the CR2032 batteries of Sig Romeo 5. 

But if you are someone who wants to have a light weighted dot sight, CR2302 can be your option. It is less bulky and heavy than the AAA batteries.
