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.

Best bang for the buck

Best bang for the buck! I have several of these red dots and for the money you can’t beat it. Great value for what you get. Very crisp red dot for my eyes with plenty of adjustment and great battery life.

Aimpoint who .?

by -

You can buy 5 of this bad boys for 1 aimpoint. Best feature automatic turn on when it senses motion then shots off after 120 seconds of no use . 50lk hours battery life . Love it

Excellent optic

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.

Until this email, I couldn’t remember who I had ordered from to return. The “dot” is crescent shaped. Far from a proper aiming device.

Well built great price.
