Side By Side Comparison

Sig ROMEO 5 is the budget clone version of an Aimpoint Micro and the Sig Sauer ROMEO 7 is like the budget clone of Aimpoint COMP4.

Both optics have their pros and cons, and one biggest difference is their size and weight.

Field Of View

The field of view is similar, but the ROMEO 5 has less optic frame obstruction to maximize situational awareness.

The ROMEO 7's brightness adjustment is a user friendly design, but it kind blocks the user's situational awareness a little.

If you aim with one eye open, the ROMEO 5 may be a better option without the size of the optic blocking your view.

Lens Tint

Both optics has slight tint, but they are not so distracting that obscures the target. In low light situations, having a light to positively identify target is recommended.

Reticle Clarity

When we compare the reticle clarity, we have to first address users with astigmatism with a couple of facts.

Fact 1: Correcting your vision is the best thing to do, and there isn't any product out there that can fix astigmatism if your eyes are bad.

Fact 2: A bigger dot appears rounder and much clearer under bright sunlight than indoor

Fact 3: Adjust the dot brightness is important under different lighting condition, so the emitter starburst doesn't obscure your field of view

What we like about the ROMEO 7 is the brightness adjustment dial is easy to turn and provides rock solid detent feedback in cold weather or when wearing gloves.

Mounts

Sig Romeo 5 can accept various aftermarket mounts because the it has the exact mounting footprint as the Aimpoint Micro. That means all of the American Defense, LaRue, Scalarworks, SLR and other mounts will work with this.

Sig Romeo 7 features a completely different mounting footprint than ROMEO 5, and many Aimpoint Comp4 mount will work with it.

Battery Life

Both optics have long battery life over 40,000 hours. For users that swap out battery every year regardless, it's not really a big issue.

The ROMEO 5 uses a single CR2032, and the ROMEO 7 uses a AA battery (62000 hours at medium setting).

Both optics feature Sig Sauer's MOTAC system to save battery when they're sitting idle. However, when transporting it in vehicles, the reticle will be activated. If you're using these optics on a truck gun, just note that the reticle will always to triggered to activate due to motion.

Turrets

Both topics feature 0.5 MOA /click adjustment just like any other red dot sights on the market.

The turrets are protected with CNC machined extrusion to prevent the dial to be accidentally moved. The turret cap feature keys to turn the dial without any tools required in the field.

Which On To Pick?

Both optics feature excellent battery life performance and features the same 2 MOA dot reticle. If you want a lightweight low profile Aimpoint Micro alike setup, go with the Sig ROMEO 5.

ROMEO 5 is also a great choice for airsoft force on force training, even if it breaks it's only $150.

If you like the Aimpoint COMP4 type look on your rifle, then go with the Sig ROMEO 7. Both optics are great options for people who may not have the fund to buy Aimpoint Products, and they last long and they work.
