I'm very impressed with this red dot. Please note you can choose between red dot, circle, and red dot with the circle. Unlike Scott above, please read the docs on how to choose the operating mode.

Priced $30 below all competitors. Quick shipping. Constant email updates regarding sale and updates on shipping. Great, economical and safe company to do business. Sig Sauer Romeo 5 XDR is a great sight with two different reticles. Two different co-witness options. Easy to setup. Great feature is auto on and off.

The Sig Romeo 5 XDR, I couldn’t be more happy with it! Love the fact it uses a simple AAA battery, has the auto shut down/wake feature and above all was super easy to sight in! I was very skeptical getting an expensive optic, kept purchasing cheap/junk ones and couldn’t get them sighted in correctly. Read and watched reviews online, Google searched Sig Romeo 5 XDR and found it on sale at Eurooptic. Very happy with my purchase, very happy using Eurooptic, fast delivery and will be using them again.

Arrived quickly. This is my first optic, but it was easy to install and zero. Very intuitive.

The XDR is what I hoped it would be, which is a bit of an upgrade from the regular model. The service, however, exceeded my expectations. In regards to service, EuroOptic is superlative!

Love the ability to switch between the 2 types of red dots! The fact that it has a triple A battery instead of the CR232s is nice as well. Overall a great optic and great price as well!

1st sig purchase. Reticle was not as defined small red dot with no crosshairs when brightness increased the circle finally showed as a red glow in the scope cutting the eye view to even small view. Sorry no more sig purchases for me.. Great customer service from euro though.
