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
  • Includes a M1913 Picatinny low mount riser and a co-witness 1.41” riser mount

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).

5 stars for the site and product. There are alot of great micro red dots for around the same price. I opted for this one as it seemed to be one of the highest quality for the lowest price. I also opted to get a single dot instead of one of the competitors with a bullet drop compensating set of dots simply because I dont want to zero my red dot for 100 yards. I prefer a 25 or 50 yard zero. So if you are looking for a red dot with no bullet drop compensator, that's high quality, and low priced. This is one of the best options. Destruction tests keep pace with optics up to the 3-400 dollar range. And osage had the cheapest price I could find of a dozen sites with free 2 day shipping Review by Randy (Posted on 4/22/2020)

It went on a CZ Scorpion and zeroed the same day. I only have about 50 rounds through it, but so far, there's nothing to dislike. I like that it comes with a high and low mount. The low mount atop the Scorpion lets me cowitness the iron sights. For my money, the Romeo 5 is the best bang for your buck on the market and Osage was a fantastic dealer! I won't hesitate to order through them again! Review by Eric (Posted on 4/20/2020)

I recently picked up a Romeo 5 to put on a pistol AR to save weight and size over using my Aim Point Pro. I haven't used the sight much yet, but after a trip to the desert to sight in and do some target practice I was pleased. It gets bright and is easy to see out in the Arizona desert in the middle of the day. The glass is good, the dot is crisp and easy to aim with and didn't have any "halo" effect or aberration in image or dot. I look forward to using it more and I am extremely happy with my purchase.

I shopped around on several websites and no one had the optic this cheap. Any other site had it 10 dollars more at the cheapest price and you still had to pay shipping. Osage is one of the best websites with shipping that I've ordered from. I have ordered magazines, recoil springs and now an optic. I recommend them to all my friends.

First off, I think this is an excellent red dot for ~$100. Shake awake/Motac. Good brightness. Brighter than my AT3 RD-50, although I would purchase an RD-50 if the romeo 5 was not available or if I just wanted a backup RD on the shelf.

I am a bargain shopper and feel this is quite the bargain. There is a lot of value in this red dot. Clear, crisp, bright dot. Has 2 NV settings also. Great battery life, easy to use controls, hi and lo mounts included on this model. All in all, a lot of value and it works great. Easy to use with both eyes open. Color difference through the optic is not distracting when using with both eyes open. Highly recommend.

There can be some reflection from the glass if the sun in directly behind you. May be present with others brands as well, just noticed it on this one one day at the range. Did not cause any issue, just an observation.

This is not a $500 red dot, however, it works fantastic for the near $100 price tag. If you are looking for a good looking, high value red dot, I strongly feel the Romeo 5 is an excellent choice.

Also, this was my first OCG purchase. Likely not my last. Website worked great, good selection and pricing, quick shipment and well packed. Overall a 5 star experience.

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?

Referenced product: SOR52001

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).

will riding in rouge pastures attivate the motac

Referenced product: SOR52001

Response Date: Feb 26, 2019

Yes. Even very minor motion (tapping the sight lightly) will activate MOTAC. It is meant to turn off when the firearm is set down and activate with any slight movement.
