The Sig Sauer ROMEO5 Red Dot Sight 1x20mm 2 MOA provides a robust 1x aiming solution for any situation. The sights are parallax-free so point-of-aim and point-of-impact remain the same. Unlimited eye-relief allows you to acquire targets regardless of the position of your eye behind the sight. With up to 50,000 hours of life, the commonly available CR2032 battery is side loading so you can replace it quickly if it fails. Romeo5 also features MOTAC (Motion Activated Illumination), which will automatically turn on or shut down based upon the optic’s movement, increasing battery optimization even further. Sig Sauer makes this optic widely adaptable to various weapons with a M1913 Picatinny system, plus low mount riser and a co-witness riser mount allow the user to customize the view to their perspective.

Excellent optic

by -

I own a couple of these. One of them is 4 years old and still has the original battery. That alone speaks to the quality of this sight. The shake awake feature is stellar and works without fail. Im not crazy about the stock mount, but that is an easy fix. Get yourself a Geissele or reptilla mount and you will have a bomb proof reliable setup. Thank you to PA for offering great prices and the fastest processing/shipping in the industry.

Great red dot sight for the price. I have purchased two of these sights and run them on my AR platforms. Their rugged and durable. A must have for those who want to run a micro red dot sights on their weapon systems.

Excellent sight for the money

I prefer this to other Romeo red dot models, and to similarly-priced Vortex red dots, as you can turn them on & off with a 1-second press of the button. The other mentioned similar-appearing red dots require turning a very stiff wheel to turn them on/off. Unless you want to leave them on 24/7/365, this is a much-preferable system, IMHO.

Well built great price.

No complaints

It works as described, now I just need to finish the ar build to put it on it lol.

Great customer service and shipping.

Easy to install and sight in . Love the easy on off and brightness adjustments.

A solid choice

by -

This is a solid choice for a red dot sight. It comes out of the box ready for your rIfle and it does what it needs to do. I own two of these and I would not hesitate to buy another if I needed it.

Sig Romeo 5

The Sig Romeo 5 red dot scope performs great! The shake awake technology is a great feature and saves battery life.

Best red dot for the money

by -

This is the second Romeo5 I have owned. Easy to mount and very easy to sight in. Holds zero well and long battery life. This one is mounted on a Stribog and works great!
