ROMEO5 Comparison Video:

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?

The ROMEO5 Compact Red Dot Sight provides the civilian and armed professional with a robust 1x aiming solution optimized for today’s MSR/AR platforms.

  • The ROMEO5 combines a leading edge optical design with an extremely robust, lightweight aluminum housing for years of worry-free service at a competitive price point
  • The 2 MOA Red-Dot provides 10 illumination settings (8 daylight plus 2 NV) for visibility in all light conditions
  • Features our MOTAC™ (Motion Activated Illumination) powers up when it senses motion and powers down when it does not. Provides for optimum operational safety and enhanced battery life
  • The readily available CR2032 battery is side-loading, allowing for quick battery replacement without having to remove the sight from the firearm
  • An integrated M1913 Picatinny interface provides industry-standard mounting options for a wide range of applications
  • Dependable waterproof (IPX-7 rated for complete water immersion up to 1 meter) and fog-proof performance

Great product and Outstanding service
I would leave a detailed review of the Sig Sauer Romeo 5 sight but, you can view those all over the internet. Plain and simple, it is worth double the list price.
BUT, more importantly is OsageCountyGuns' service and logistics. I placed this order and a package label was created on the same day (according to USPS Informed Delivery). The order of this sight was well packaged, neat, and surpassed all of my expectations. For a business to offer this optic at nearly 20-30% off AND, have it in my hand on the 3rd business day is something I wish many other sites/companies would emulate. The level of this transaction is of which I will be back to support those that put not only passion into the 2A community but also, show what truly separated the apprentices from the artisans.
Thanks again OCG for providing a level of service that has the speed of Amazon but, providing customers email updates that actually work (with real tracking numbers/unlike amazon).

Very Respectfully,

Better than expected.
It shipped quick. Received it within a few days. Placed on 300blk and sighted it in at 25 yards. It was dead on with in a few minutes, small adjustments. Will definitely buy another one when back in stock. Review by Ed (Posted on 4/20/2018)
Solid product, and great buying experience.
Product came with free shipping, and was delivered to Alaska via 3 day prioity mail. It seems like they took the extra step to make sure I got my order in a timely manner.

Awesome FOV on the optic, with plenty of brightness settings for use in any environment. Perfect optic for my .300 Pistol.

How does MOTAC work? My Romeo5 doesn't seem to turn off like it should.

The Romeo5 and other Sig Electro Optics that have MOTAC (Motion Activated Illumination) are very sensitive to any motion or even vibration.

From Sig Sauer: MOTAC increases battery life by shutting down the system when not in use and instantly activates the system when it senses the slightest vibration or movement. Your sight will be up when you go into action. The ROMEO5 will mount on any platform and the solid aluminum design will give peak performance and years of service.

We have sold thousands of Romeo5 optics and have never seen one that had a defective MOTAC feature. To test the MOTAC feature, turn on the optic and place the optic on a solid surface that has no vibration (a table top, desk, or chair) in a manner in which you can look through and see the dot without having to move or touch the optic. Ensure that there is nothing which might create a vibration and let the optic sit for approximately one minute. The reticle should turn off. You can look through the optic and see that the Romeo5 shuts itself off. If you tap or even slightly move the optic, it will turn back on.

Very slight vibrations, even those from an incandescent light (a customer tested his on the shelf of his safe and an incandescent light was mounted on the underside of the shelf) can prevent the sight from shutting itself off.

I just received my Romeo5 and it doesn't seem to work. What should I do?

There are a few steps to troubleshoot the Romeo5 to verify if it is functioning properly.

First, please check to ensure the battery is installed properly. The positive terminal should face away from the optic as shown:

Sig Romeo5 Battery Installation

Next, press and hold the + button on the top of the Romeo5 for approximately three seconds to activate it. It is possible that the intensity is turned down very low where the dot is difficult to see. Press the + button five to ten times to check if the dot becomes visible.

Last, if these steps do not work, it is recommended to test another battery, if you have one available. The Romeo5 uses a CR2032.

If you still have problems after trying the steps above, we recommend calling Sig Sauer's support staff by calling 603-610-3000 (option 1).
