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).

Romeo 5 is still one of the best Red Dots on the market Review by DEAN (Posted on 3/26/2020)
Excellent value - Motac & bright

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.

I guess I had the same problem as others, it wouldn't come on and I thought it was dead on arrival. Kept messing with and finally got it working. Performance is great and have had no other issues. Dimming the dot allows for making accurate shots with my 10-22. Happy I found it for the Black Friday price. Review by BILL (Posted on 12/9/2019)

This is my second Romeo 5 I own. The first, I owned for several years and it has preformed flawlessly. I also own Sig pistols that I really enjoy. Hands down for the price there is not a better red dot. Additionally, the inclusion of of both a high and lower rail is not available on many competitors product. Finally, the auto off feature is outstanding and optics are very clear and easy to acquire the dot. I watched a YouTube torture test where they even shot it with 12 gauge buckshot and it continue to function normally. To me, I won’t purchase any other red dot.

Bought 2 of the Sig Romeo 5's on Black Friday for a great price, they are a very good product for $100, and met all of my expectations. The real deal is dealing with Osage. They were fantastic, shipping was more than fair, and the items got to me exceptionally fast. I will deal with them again, in the future. Review by Jimmy (Posted on 12/5/2019)

This is my 3rd Romeo 5. While I prefer holographic sites, I'm not going to spend 350-550$ a pop to put those on every rifle. Three Romeo 5 weeks as advertised. For 100$ I have no complaints. Coming with a low and a high mount is a nice touch also. Highly recommend this as a budget rds. Review by John (Posted on 11/13/2019)

OCG had the Romeo5 at a great price. The optic speaks for itself with ease of use, and the auto on/off with motion initiation is exactly the selling point I was looking for. Super fast shipping, easy online purchase. Thanks for making it super easy!! Review by Oran C. (Posted on 11/11/2019)

I ordered three Romeo5s because of the excellent deal OCG was offering and my prior flawless experience with this sight. Checked the sights out last night and everything was in good working order. I have been ordering accessories for my rifles and handguns online for two decades and I have never seen such rapid communication and shipping as offered by OCG. Simply outstanding!! I will be back and I can recommend OCG unreservedly to others. Review by jlebowski (Posted on 11/6/2019)

I held back on the 5th star because the dot has more glare/starburst than other RDS's I have used. A little annoying, but functionally it dosen't make much difference, at least at the distances I use it for.
Otherwise it seems to be a great sight and will solve my little problem of always forgetting to turn the sight off...I'm not sure I will ever be consistent about that...but just as important, I don't have to remember to turn it ON, which is potentially just as critical.
Have not fired any rounds with it yet, but between this unit's reputation and Sig's warranty, I'm confident that it will perform.

Product Questions

Product Questions

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).

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.
