NEW: SIG Sauer Romeo Sights

SIG Sauer continues their strong move into the optics market with their new Romeo red-dot lineup. The Romeo optics include the Romeo4, Romeo5, and Romeo7. SIG promises exceptional clarity and improved target acquisition with these optics, among other things. It seems clear the company’s plans to expand beyond firearms and into other gear such as optics and ammunition is a success.

The Romeo4 category of red dots actually includes three models: the Romeo4A, Romeo4B, and Romeo4C, and Romeo4M. The “A” is the baseline model with a 2 MOA red-dot, the “B” has a 65 MOA/2 MOA circle-dot, and the “C” has the additional feature of solar power. The “M” is the MIL-SPEC model. SIG describes these as models best for fast target acquisition on both stationary and moving targets.

The Romeo5 is a micro version designed for versatility. This particular model has the company’s MOTAC – Motion Activation Illumination – feature. MOTAC is meant to extend battery life by shutting down when it’s not being used. The optic is designed to turn back on when it’s moved and is activated by vibration and larger movements.

The Romeo7 is a full-size optic specifically designed for MSR platforms. Features include a wide field of view, increased light transmission, and zero distortion. The dot itself is designed to be as bright as possible but perhaps best of all is the battery. Battery life is listed at 62,500 hours and the battery itself is a AA. The AA battery is located in a compartment that’s accessible without removing the optic from the firearm, meaning it can be replaced without dismounting.

MSRP: Romeo4 $299.99-499.99. Romeo5 $199.99. Romeo7 $299.99.

  • Paul O.

    Anyone have hands on experience with these?

    • G B

      Yeah, the reticles have been crooked on 3/3 of the ones that I’ve looked through. Varying degrees of crookedness, one was hardly noticeable but the other two were pretty bad. The two bad ones were crooked enough that you didn’t even have to mount them to a rifle or set them on an even surface to be able to tell. One of the very crooked ones was at a shop in Florida back in May, and the other very crooked one was at a shop in Virginia in June. The one that wasn’t too bad came with my friend’s MCX when he bought it about a month ago. Also they’re much closer to Vortex/Bushnell/Primary Arms than they are to Aimpoint as far as clarity and dot crispness go. That’s about all I know.

      Edit to add that all three were the Romeo4B models.

      • Russ Kell

        Sigh. I was hoping they would be over better quality than their line of prismatic optics, but it doesn’t sound like it…

        • Mark K

          More than likely they are Chinese made – crapola.

  • jonjon7465

    What direct mount compatibility do they have? Aimpoint mro?

  • Sunshine_Shooter

    I won’t be impressed until the micro red dot of their’s has been mounted on pistol slides and tested for durability. That’s the true test of a red dot. A cheap sub $200 red dot can last for years on top of an AR no problem.

    • Sunshine_Shooter

      After perusing the Sig Electro-Optics website, I’m fairly impressed. Their Romeo1 sight seems to be made for mounting on pistol slides. I still want to see how they hold up after a few thousand rounds, but I’m a little less skeptical now.

      • nova3930

        Same here. After saying in a prior post how I had not seen a Romeo 1 in the wild, I walk into my LGS and there sits a P320-RX with a Romeo 1 perched on it. I’m sorely tempted to trade my normal P320FS on it since even if the R1 is junk, it’s still a pistol pre-setup for a red dot optic…..even if it might required a custom adapter plate for an RMR….

        • Sunshine_Shooter

          Hopefully that means that will see more reviews from individuals soon. That being said, do it! Get that optic equipped pistol and see how it handles a 1,000 rounds or so.

          • nova3930

            it’s on lay a way now. if I decide to trade my FS it may come home pretty quick. I may keep both though. just have to see

  • Sam

    I read on one of these comment threads that Holosun or somebody… Primary Arms? Was making these. Any truth to that?

    • Sunshine_Shooter

      I highly doubt it. The bodies are all completely different and the price points are vastly different. Those things, combined with their in-house manufacturing of suppressors as well, make me believe that they are building these in house.

      • raz-0

        The stuff that makes suppressors doesn’t really translate to optics. That’s like saying my local diner manufactures bedding because they have a bakery attached.

        I doubt it’s in house, design and engineering may be, but production probably is not. Some of their stuff has some pretty sophisticated electronics in it, and it’s unlikely they are not consulting with an outside party for that either.

        • Sunshine_Shooter

          According to another commentor who got one, it said “Designed by Sig Sauer in Oregon Assembled in China”, so it looks like they are indeed produced oversees.

      • UVB76

        No – actually look at the components. Really look or buy a Holosun model to compare and return after…SIG had Holosun change a few cosmetics and make some little improvements (hex vs phillips) but the basic sight components are spec’d the same. Same mount/same battery life/same tray/same dimensions/dot size and reticle selection/modes etc. I don’t consider the Holosun affiliation a bad trait – actually a good thing (based on experience and testing).

    • Flounder

      The are not at this time made in house by sig. Sig subcontracts to an unknown company. All sig admits is that right now they are “gearing up” to make them in Oregon.

      With the features i would be stunned if they were NOT holosuns. They are the same size, weight, style, and have identical features. Although that is hardly conclusive to be fair. These really look like slightly improved holosuns. As far as the body goes. like the turrets being protected better which is what holosun started to do in their second or third “generations”. (They have revised their models slightly since their introduction but they usually don’t distinguish models in a consistent manner. They are new enough at this I don’t find it a huge problem)

      And I know of no other company making such a similar product other than holosun.

    • Flounder

      I forgot to mention Primary arms and Holosun are… Partners? Holosun makes primary arms red dots as well. I just don’t know the exact nature of their relationship.

      I know holosun is an OEM for Primary Arms’ red dots. So Holosun is not as new a brand as you would think.

    • UVB76

      Yeah – take a look at the mount and specs. Either Holosun is building them for SIG or they are sourcing the Holosun components and manufacturing at a related facility (in China). Wouldn’t call it a negative.

  • Where are they made? No official info I was able to find, except for having a 5-year warranty.

    • Kelly Jackson

      I don’t know about the digital optics, but the glass scopes are made in Japan.

    • Flounder

      Made in china, it’s on sig’s site. These have a 2 part warranty. One part covers electronics and possibly the glass and the other part covers the body.

  • ReadyorNot

    Where are these being made? Seems eerily related to Holosun/Primary Arms.

  • KN1719

    A Romeo 4 came with my MCX, it says on the box “Designed by Sig Sauer in Oregon Assembled in China”. As for the overall quality, I cannot say for certain as I never used it. Though the functions it boasts are ideal, I only played around with it for a little, before selling it. I have an Aimpoint T1. The model I had, the Romeo4B, could switch betweeen 2 MOA Dot with 65 MOA Circle or just the 2 MOA Dot. It may have been my eyes, but the circle dot was ever so slightly canted. Clarity was not bad and both the circle and dot were pretty sharp looking. Some of the finish on the front end was very thin and looked like it had rubbed off onto the included bikini covers. Although the body looks different, the buttons on top, etc. look very similar to that of PA and Holo. I also believe the warranty is more than 5 years and is a no fuss lifetime one.

    • nova3930

      “Although the body looks different, the buttons on top, etc. look very similar to that of PA and Holo”
      Probably because they’re all using the same component OEMs where possible. Part of the reason so much of the stuff coming out of China looks so similar despite having different manufacturers is they all use the same OEMs for the sub-components, just putting those components together as they see fit.

  • Stan

    I would definitely buy one of these except that they all have the battery compartment stuck onto the side of the tube where it kinda limits your field of view. Are that any decent, affordable sights like this without the battery on the side of the tube?

    • KN1719

      Actually the battery compartment is inside the optic’s base and is inserted through the side via a plastic tray that you unscrew two torx screws to get out. This is for the Romeo4.

    • Kelly Jackson

      Frankly I like that it runs off a commonly found battery.

  • KN1719

    It appears one of the Romeo4 out of the different models is exactly as you described, my mistake! I know the 4B model, which is similar if not the exact one shown in this post uses the battery tray.

  • Disarmed in CA

    Where fore art thou?


    I like the idea of a “Microdot” that works off a normal off the shelf battery. Keep it up sig.

  • Bill

    I really dig the circle/dot reticles, but I’d really dig it more if it came from Aimpoint or Trijicon. I wish SIG, and other manufacturers, would partner with companies that produced at their level of quality.

  • Orion Quach

    How the hell do these Chinese optics keep getting more and more expensive?

    • UVB76

      Some is the SIG affiliation – the other is that they are getting closer to European and American technology specs (still a tad behind on reliability from optical system standpoints). Hence the price gap closes a bit.

    • Stan Darsh

      In this case, the SIG roll mark. These are re-branded Holosun units that SIG is selling at twice the price.

  • UVB76

    Romeo 4B SOR41101 = Holosun HS515BU (derived)
    Romeo 4C SOR41201 = Holosun HS515CU (derived)

  • JumpIf NotZero

    So it looks like an Aimpoint.
