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.

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.

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!

Come for the price, stay for the quality


You'll wish you bought more of them while they were on sale. This Sig red dot is tough. You can bang it about without it missing a beat. The auto on/off feature is great. Pick up your weapon and before you can get it to your eye it's on. Set it down and in a couple minutes it turns off. How many times have you found your red dots dead because you forgot to turn them off? It's happened to me a lot. That is a thing of the past with this site. People say it's a good sight for the price. I say it's a good sight at any price. Get 1...or 5 you'll be glad you did.

Awesome red dot sight and the price was definitely right!

I love the Sig Romeo 5

by -

I have probably bought at least 10 of these red dots and the quality has consistently been good. My favorite is the motion activated illumination, to me it makes it so much faster/reliable if I hear something go bump in the night. They hold zero very well and to date the optics remain clear

Outstanding RDS for the price!

Just bought my third Romeo5. They are extremely durable, stable windage/elevation settings, excellent clarity, a true 1x, long battery life with motion sensor feature. Comes with high & low mounts, perfect co-witness on AR platforms. Crisp dot with no fuzzy edge. Get one... or two, or three like me!

I like it

I got this on sale and could not refuse the price. The glass is clear and the red dot is crisp. The diameter is small so co witnessing with iron sights restricts my view.

Pew pew

Awesome red dot and the price just sealed the deal for me. Put it on my 7.62x39 AR and it is on point.

Great deal!

I am very happy with the Romeo5. Rugged as all get out and keeps far so good! And with the sale prices Primary Arms offers, you really can't go wrong. Keep your eye on these guys!
