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.

I wasn’t expecting much, but this is a solid optic so far. Very clear and easy to co-witness.

Hands down, from the standpoints of features and quality, this is one of the very best values in red dot rights. I have two - both from Primary Arms.

Nice Micro alternative


I usually like to put Aimpoints on all my rifles, but if I did that for everything I have in my safe I'd be living in my car.

Alabama Arsenal did a great review on this sight. Check it out on their Youtube Channel. This site is very well made. The bikini covers it comes with are garbage, but who cares? The mount and sight itself are well made, and durable. For the money, it's hard to beat this RDS, and I'm putting them on my rifles that don't have Aimpoints. These sights are made by Holosun, and they have earned quite an impressive track record for quality and durability.

Cant beat the Romeo line up.


My first Romeo was a 7. Awesome sight but full sized. Figured the 5 would be just as awesome and I was correct. Romeo 5 is the best bang for the buck. Perfect match for my PSA47. The low mount gives great co-witness. Had to order two more for my MP5s. Buy it! You won't regret it.
