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 red dot for the money

by -

Bought one on sale and loved it so much that I bought a second one. Don't know why I waited so long to try the Romeo 5.

Does what it supposed too.

Nice red dot. Quick shipping

Decent for the price

by -

It is a decent red dot. It will get the job done. The dot is not as sharp as say an Aimpoint, then again no where near the price.

Great scope at a great price

by -

I now have three of these. a great red dot scope for all long guns and even pistols. Good price and fast delivery as always.

I confess to being a “red dot snob”, thinking for years that I HAD to spend several hundred dollars on a sight to buy anything nearing decent. This Romeo5 has absolutely changed my mind. I was, and am shocked at the features, performance, and quality. Add the fact that it was barely over $100, and I’d call it a best buy.

Great purchase

Great product.

Romeo05 is one of the best affordable red dots on the market. I’ve placed several on my high powered weapons as well as my friends’, and have had no problems with any of their reliability.
