Sig's ROMEO5 red dot sight is a small, lightweight enclosed red dot sight. The Romeo5 features Sig's MOTAC system (motion activated illumination) which turns the sight off when it is not in use. It activates instantly when it detects the slightest vibration or movement. The feature helps drastically extend the battery life of the sight.
The ROMEO5 includes a total of two risers, one is a low mount riser and one is a 1.41 inch riser (pre-mounted on the Romeo5 in the box) to co-witness with iron sights.
The ROMEO5 will mount on any platform and the solid aluminum design will give peak performance and years of service. Military units trust the ROMEO5 when it counts, so why wouldn’t you?

We have received a few inquiries from customers regarding the Romeo5 and there are a couple things to check if you buy a new Romeo5 and it does not appear to be working:
First, make sure the battery is installed correctly with the + facing away from the scope (the + side should be visible when the battery is installed)
Next, press and hold the + or - button for about two seconds to activate the sight and then press the + button about six to eight times to ensure the dot is visible (sometimes it is set so low it doesn't appear to be visible but is indeed on).
MOTAC is the motion activation feature of the Romeo5 and is very sensitive. The most minor vibration will activate it. We tested it and found that the vibration from a speaker on a desk while the optic is sitting on the desk is enough to activate it.
The Romeo5 uses a CR2032 battery that should last a long time. If you are burning through batteries quickly, make sure something isn't vibrating or touching the optic to frequently cause it to activate (for example if it is in a vehicle, it will always activate from the vibration of the engine and driving).
