Sig Romeo 6 vs 7 – How do they compare?

Battery performance

Without a battery you won’t be able to see anything through your red dot sight, most of these units are, therefore, equipped with highly durable batteries. Despite the above, you must always invest in a new battery at least once every year because they rarely achieve their full shelf life. And depending on the type of red dot sight that you are using, the frequency of battery replacement will vary, for some units, you will have to replace them frequently within the year because the batteries have a short life span.

The sig Romeo 6H offers users up to 50,000hrs of battery life, while Sig Romeo 7 offers a minimum of 40,000hrs of battery life, however, when used in the medium illumination setting the battery will offer up to 62,500. The above then make the Romeo 7 the better unit because the incorporated battery tends to last longer when used on the medium illumination setting.

Brightness settings

The brightness settings in red dot sights are perfect for precision, and the reason they are many is because they are used in different lighting situations. In essence, is that the brightness settings should offer precision in low light and daylight environments. And that is why the Sig Romeo 7 is the best unit as it offers users up to 2 customizable night vision settings and up to 9 brightness settings that you can use in different daylight situations.

Unfortunately for Sig Romeo 6, there are no dedicated night vision settings but users get about 12 brightness settings meaning that the sight is still able to afford the user’s precision and accuracy in the different lighting situations, even when being used indoors.

Build and Structure

Romeo 7 is a heavy unit, which you can tell from the incorporated features leading it to weigh 8 ounces. The unit is quite sturdy and comes with two different types of mounts to enable users either have the night vision or magnifier attached to it, the low profile mount is to allow accommodation on other firearms that aren’t AR.

On the upper part, you get the modern protective turret housing that is easy to open, no need to use a coin. The battery compartment has been conveniently placed to allow easy access during use and for this feature, you also get the tethered caps that you can easily open and close without worrying about losing the caps.

The 6H is made of the rugged aluminum housing, and just in case you didn’t know the H in front of the 6 stands for hunter meaning that the unit can be fitted on a bow, or hunting gun and will take the beating of a rough terrain but remain effective. The battery tray is on the side, but not the easiest to access when compared to the Romeo 7.

The unit has also incorporated the transparent flip caps, and a feature that you are going to love with this sight are the brightness adjustment buttons, incorporated on the side, very easy to reach, and which you can also use to customize the reticle.

So as regards build and design the Sig Romeo 6H is the better unit because the dials are pretty easy to reach and weighs less than Sig Romeo 7.
