First Impression

Very clear front lens and good overall presentation

The Sig Sauer ROMEO5 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 ROMEO5 can accept Aimpoint Micro mount, so see what that looks like.

Core Features

Window Size

The 1X20mm objective lens look similar to an Aimpoint Micro and other Holosun budget red dot sights.

Reticle

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

The ROMEO5 features a simple 2 MOA center dot

The 2 MOA dot is pretty standard for an optic this size. It's big and fine enough for long range and close range engagement.

At 100 yards, once the dot is zeroed, the 2 MOA 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

Under a hot sunny day, the 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 battery compartment can be accessed from the side. Pretty much all optics like the ROMEO5 is built this way.

The battery lasts about 40,000 hours, and at this point of the review process, we can confidently say that the sight has already lasted 2 years without failing. So at minimum you get 2 years, and you have enough time to swap battery if you want.

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

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

Construction

The body of the Sig ROMEO5 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, ROMEO5 is a solid product at a great price point.

Get it as your 1st RDS or use as a spare

Turret Adjustment

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

The ROMEO5 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 give 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.

Mounts

Please ditch the default mount that comes with the optic and use something aftermarket for better zero retention.

The factory mount isn't good for retaining zero when constantly taking the optic on and off the rifle.

Same mount footprint as Aimpoint Micro

The optic uses Aimpoint Micro footprint. So all aftermarket mounts for Aimpoint Micro will work.

Our favorite one is the Scalarworks LEAP. Please check out our review on this mount.

It's lightweight and slick looking for the ROMEO5.
