SIG has a new motto proclaiming themselves a “Total Systems Provider.” They seem to be living up to that name by making not only handguns and rifles but also optics, flashlights, lasers, sights, suppressors, and more. The SIG Romeo5XDR is just one of many optics on a long list of them. Numerous forces, including the FBI, have approved the Romeo series, and these same optics have been found on rifles used by SAS Operators. The Romeo5 series is the more affordable model designed to be compact, lightweight, and simple. The Romeo5XDR seems to be a hidden gem among the Romeo5 series.

XDR is an acronym that tells you everything you need to know about what makes the XDR different from the standard Romeo5. X stands for extended battery life, and the Romeo5XDR will last for 50,000 hours on a single AAA battery. The DR stands for the dual reticle. The first reticle is your standard 2 MOA red dot, nothing fancy, but something can be said for the efficiency of simplicity.


The second reticle is my favorite. It’s inspired by the famed Eotech reticle. It is a 65 MOA circle around a 2 MOA red dot. This gives you a bigger aiming point for quicker close quarter’s use and the smaller 2 MOA dot for longer range, more precise shots.

What’s Important about the SIG Optic?

The long battery life and dual reticle are a nice touch, but there are a few more things you should know about the Romeo5XDR. It’s rated IPX-7 for waterproofness. This means it can be fully submerged up to 3 meters.

It uses SIG’s MOTAC technology to have an always-ready optic. MOTAC stands for Motion Activated, and the Romeo5XDR has a built-in on/off switch based on how much motion the optic picks up. When left still, like in a gun safe, the optic automatically switches off. However, as soon as it’s grabbed, the reticle comes on, and the optic is ready.
