First Impression

Very clear front lens and good overall presentation

The Sig Sauer ROMEO 5 is small and lightweight! The construction of the optic looks slick and the edgy cuts make the sight feels very true to the Sig Sauer's brand.

The turrets feel solid, the lens looks clear just like any other reflex sights, and based on the specs, the ROMEO 5 can accept Aimpoint Micro mount, so see what that looks like.

Main Sig ROMEO 5 Features

Window Size

The 1X20mm objective lens look similar to an Aimpoint Micro and other budget options.

Reticle

In rain, just crank up the brightness intensity and you're good to go under a cloudy day.

The Sig ROMEO 5 features a simple 2 MOA center dot

The 2 MOA dot is pretty standard for most red dots this size for close target acquisition.

At 100 yards, once the dot is zeroed, the 2 MOA red dot covers about 2" circle and it's just as accurate as an Aimpoint Micro (assume proper mount & zero).

For shooters with astigmatism, the optic has 8 day light settings and 2 night vision settings to help you adjust the reticle brightness and clarity.

Based on years of experience, the only way to counter astigmatism with an reflex sight is to wear corrected lens and go with a 6 MOA dot (recommended for pistol red dot for the most part)

For cross eye dominant shooters, the only thing the shooter can do is train to aim with the eye on his/her the dominant side. Read more by clicking on the link.

Reticle Brightness Settings

Under a hot sunny day, the Sig Romeo 5 reticle is visible on max daylight setting.

On a cloudy day, the reticle appears starbursted if the brightness is cranked up too high (recommend cranking it back down until it's right for you)

Battery Life

The Sig Romeo 5 battery life is about 40K hours on a single CR2032 battery, and the battery compartment can be accessed from the side like an Aimpoint Micro.

The optic at the point of writing this review has already lasted 3 years without dying. Not to mention that it's off when sitting idle, which saved lot of battery juice.

In addition, the optic features Sig Sauer's MOTAC system that saves the battery juice while it sits idle, and reactivates when it senses motion.

So far, the optic has always stayed operational even after multiple range trips throughout the last two years.

Sig Romeo 5 Construction

The body of the Sig ROMEO 5 just look slick. Just look at that!

The body is made of 6061 T6 aerospace aluminum, and it's durable for normal use on carbines and PCC.

As far as holding zero goes, the sight holds zero under normal use. So far it has not lost zero whatsoever.

As red dot manufacturing technology has advanced in the past few years, more and more optics can perform like some of those expensive ones, and the price keeps dropping as demand increases.

For new and experienced, the Sig ROMEO 5 red dot is a solid product to buy at a great price point.

Turret Adjustment

0.5 MOA / Click is what you get with this red dot sight, and it's pretty standard for 2 MOA red dot across the board.

The Sig Sauer ROMEO 5 provides plenty of adjustment click range (100 MOA for elevation and 100 MOA for windage). On a normal optic to bore distance gun, there is plenty of elevation dials to zero the dot before the turret dial maxes out.

The elevation and windage turrets are exposed without any extrusion wings around it to protect it. It's not a big deal for an optic at this price range, and the part we like a lot is that the turrets are very responsive, and it gives very positive feedback even when wearing gloves in the cold.

The turret cap has built in flat head extrusion to dial the optic, and it's labeled Up/Right to reference the point of impact shift

(NOT reticle point of aim)

If you've ever experienced reticle moving opposite of turret dial, we wrote an detailed article explaining to help you out.
