FBI To Issue Sig Sauer ROMEO4M Red Dot Optics

After competitive solicitation, the FBI has chosen the Sig Sauer ROMEO4M red dot sight as a new general issue optic for patrol carbines. After a TFB Exclusive in November where the FBI approved the ROMEO4M for use on personal rifles in addition to the previously approved Aimpoint series, the FBI selected the optic for general issue starting in 2017.


The ROMEO4M is not just a red dot optic, it is inspired by EOTech with the option of just the 2 MOA Dot or adding a 65 MOA circle. The optic features 12 brightness settings including 10 for daytime operation and 2 for night vision. The main tube is 20mm, which has + / – 50 MOA of adjustment on both windage and elevation in 1/2 MOA increments.


The battery is side-mounted (right side relative to the shooter) and is IPX-8 rated which makes it waterproof up to 1 atmosphere of pressure (Sig states 33 feet underwater for 30 minutes). Available mounts include low-profile, and co-witness mounts in both screw-on and Q/D configurations.

Further, the ROMEO series includes Sig’ “MOTAC” (Motion-Activated Illumination System) technology, which gives the optic a rated 50,000 hours of “normal use.” In short, MOTAC uses motion-sensing technology to turn the optic on instantly and off when not in use.


The sale itself is through Tidewater Tactical, a dealer specializing in commercial and law-enforcement sales. Delivery begins in “government Fiscal Year 2017”, which means units are likely already in the FBI’s hands as FY2017 started in October.

  • Ambassador Vader

    Why is the sale through tidewater and not just through sig?

    • datimes

      It jacks the price up as Tidewater doesn’t do a sale like this and not make something for the time and effort. Or more money for Comey & his homey. Or they supplied products for testing and support. Or…

    • Harry’s Holsters

      Probably because Sig isn’t a Transgender, minority, immigrant, sometimes female native american veteran owned business. Did I leave anything out?

      A lot of companies that compete for government contracts put the wife down as majority owner as it helps in winning the bids. There is a reason you see more “tactical” gear companies pasting female veteran owned business all over their websites. The same thing goes for disabled veterans.

      I appreciate what our veterans have done but I think the only things that should matter with a government contract are price, ability to provide service and owned and produced in the USA when applicable.

    • Joseph Goins

      Sig didn’t apply to the solicitation as they are not dealers.

  • Harry’s Holsters

    I now feel better about buying one and will.

  • whome18t

    Aren’t these Holosun made in China? I thought the government can’t acquire foreign made products without congressional approval?

    • yodamiles

      Yeah, I’m trying to find something about that because as far as I know, it is produce by same manufacturer as holosun.
      Sig might have brought it in to produce in the US but I don’t see anything yet…..

      • whome18t

        Either someone just didn’t care, or Sig is using some kind of loophole, or they are actually made in the US.

        I’m familiar with this law because I remember the big brouhaha over the Olympic uniforms being made by a foreign countries a few years ago. Not because it was ironic and unpatriotic, but because it was illegal.

        • yodamiles

          TFB should do an article about this….some investigation journalist stuff

        • The Berry Amendment only applies to the DOD.

          While the US Olympic Committee is a private nonprofit corporation (501c3), so no US law like that could apply to them.

    • Teddy

      Forwarding this to the president-elect now…

      • Minuteman


    • Flounder

      When they launched sig said they were made in china with plans to make them in the us.

      Specifically sig said they had plans to make them at their oregon electro-optics facility.

      And it is either made by holosun or a clone of holosun with some minor changes. but china isn’t big on patent infringement. So who knows. No one from sig or holosun will comment.

      • Frank

        Beretta do that don’t they? Assemble mostly foreign parts for Steiner scopes and slap the “made in germany” label.

      • Bill Jacobs

        What I heard was holosun made laser and LED stuff for a lot of companies for 10 years. Then started making optics and making them for other people. Heard this from rep. from another competitor to holoson and sig.

    • Sgt. Stedenko

      The M at the end tells you all you need to know.
      Mil Spec and not made by Holosun

      • Bill Jacobs

        Holosun can’t make Mil Spec? Actually Holosun is putting a dent in optic maker out there. I think Sig said, if you can’t beet them join them.

    • You are probably thinking about the Berry Amendment, that is mostly for textiles and metals.

      I am not aware of any requirement for US made for other products. Though I believe they are supposed to give preference to American made products.

    • UVB76

      Aimpoint and Elcan… Both Foreign even if they have a US based HQ.

      • whome18t

        Those are an exception since they come from NATO countries. Aimpoint is made in the US also.

        Though, there have been plenty of govt contracts today that go to foreign countries when they shouldn’t…but people just don’t care :/

    • micmac80

      Yes making America great again one chinese optic at a time.

      • The Brigadier

        Trump is going to change that, or so he says. Lets wait and see shall we?

  • MrBrassporkchop

    So in a few years will people claim Aimpoints are “junk” now because everyone uses Sig optics?

    • David Harmon

      Doubtful, these “Sigs” are made in China. China has a long way to go before it’s up to US quality standards.

      • Mrninjatoes

        Really? Because my IPhone is a piece of garbage?

        • Minuteman

          I was just about to say the exact same thing.

          Samson’s glass is Chinese as well, yet it’s a top notch magnifier. Not everything made in China is crap. In fact they’re really stepping up QC and certainly capable of manufacturing solid gear.

          • The Brigadier

            They have many decades to go yet . QC cannot be done overnight and took our nation many years of developing the principles behind modern manufacturing quality control before we got it right.

          • Minuteman

            Yep, but they’re gettin’ there. Nothing wrong with the glass in Samson magnifiers. And my Iphone works just fine, I assume yours does as well. I wouldn’t be all that too harsh on China. They’re stepping up their game.

        • Frank

          The iphone is assembled in China with parts that come from probably a dozen countries. When Chinese made lithium ion batteries stop exploding and forcing companies to recall entire model lines then they’ll have figured it out. By the time they figure that out, it won’t cost much less to manufacture things there.

        • Matt Taylor

          It sure is. Lol.

        • David Harmon

          Yes, all smart phones coming out of that country are garbage. If they weren’t you wouldn’t be buying a new one every couple of years. Electronics do not wear out. Batteries do, and software is forced in obsolescence through poor optimization…

          • The Brigadier

            TVs don’t use batteries and Chinese made sets fail after two years. Samsung TVs that are made in China fail after only three years. Do you all remember when your old sets made here lasted fifteen years and some better brands lasted twenty? Its a matter of using higher grade electronics and using wave form soldering that eliminates oxidation and solder failure. Its still cheaper to use tiny, nimble fingered Chinese women to do the soldering with all resulting failures. China makes crap. Its time to take our manufacturing back and show the world again about how its done right.

          • Minuteman

            I have sympathy for your argument, but those days have passed man… It’s a different world now.

          • David Harmon

            I don’t own a TV, and never have.

          • Minuteman

            I’ll tell you one thing though: each and every Samsung phone I’ve had in my life had serious issues. Never had any problems with Iphone whatsoever. China -with hands on oversight from the actual overseas brand- IS capable of putting out quality gear. Just look at Iphone. These things are not at all cheap and would simply be unaffordable if it weren’t for Chinese manufacture. I doubt Apple would even exist without the Chinese. Trump can talk all he wants about bringing jobs back from China, from Mexico etc etc, but we’re living in a free market economy, whether you like it or not. This isn’t the 1950s anymore. Labor in the entire Western world is expensive and that reflects consumer price.

      • Badwolf

        And we all know US made stuff never go wrong. Eotechs are like… the best… ever.

        • Maximilian Johannes Benning

          let’s not even get started on our cars. lol

          • Frank

            To be fair, half of that is because of mexican parts. A Honda accord is made in the US with mostly US parts and is one of the more bulletproof cars to buy at the moment. Meanwhile most US marques are loaded with more foreign parts.

          • Matt Taylor

            Toyota would argue that point sir. 🙂

          • David Harmon

            Honda and Toyota are built in the US.

        • David Harmon

          Sure, except it wasn’t a reliability issue that killed EOtech. It was a faulty design, and expiration of patents. I prefer Americans, and would rather buy something made by them.

          • Badwolf

            There are many other examples, like Remington.

            Don’t get me wrong, I prefer American made as well. I just don’t harbor any illusions that American made automatically has better quality control. Wherever it’s made its the American boss that’s sets the quality.

            I’ve worked as a consultant in many factories all over the world. The only difference between all these countries is cost of litigation if your product blows up. For example you want a certain product or part made, you go to an American factory… Usually answer is of course, depending on how much you’re willing to pay I can give you high, medium, or low quality.

            If you ask a Chinese factory, they give you the same menu, high, medium, or low quality. But they have an additional level, the super low POS quality. American factories are afraid to go this low because if the product blows up they will go bankrupt from lawsuits. But Chinese aren’t afraid to offer this because they can absorb the damages.

            But in any case, wherever it’s made, it’s the American boss that sets the quality level, depending on how much he’s willing to pay the factory. So I don’t get it when some people blame china for bad products because thats exactly what the American boss paid them to make.

          • David Harmon

            Remington is the result of foreign owners taking control of an American company to gut it and dissolve it for short term gains.

          • Badwolf

            Whatever man… you’re moving the goal post.

          • David Harmon

            I didn’t move anything.

      • pun&gun

        The Chinese companies turning out higher-end knives are arguably beating the rest of the world’s manufacturers right now. Reate, Rike, and Kizer are turning out some very high quality stuff.

      • Renato H. M. de Oliveira

        Chinese products are very “bang for buck” based.
        They will sell with the quality you’re willing to pay.

        • David Harmon

          I.E. not at all to me. I want American made products, not Chicom slave labored garbage.

          • Renato H. M. de Oliveira

            Lotsa things are at least partially made in China today.

      • Bill Jacobs


      • The Brigadier

        They have no idea about modern quality control standards or uniformity of sizes or material constancy. We need to bring back manufacturing to the U.S. because it will also bring back 4 trillion dollars in income to our GDP. It will be much easier while we still have skilled people young enough to build the factories the right way and they can teach younger workers correct manufacturing principles. If we wait too long a lot of these folks will be dead.

    • Minuteman

      To tell you the truth, I actually do prefer the HWS. It’s just that their battery runtime is pathetic and they’re so damn unreliable that I’m an Aimpoint man. I like the SpecterDR 1-4× over Aimpoint as well, but it uses an odd and kinda hard to come by battery and the runtime is not on par with Aimpoint.
      Aimpoint, to me at least, is King. Trijicon is not far behind at all. I love the TA02. I just prefer the Comp M4S and Samson X3.5 for ease of use and flexibility. This setup will do basically the same thing as the ACOG in the magnification realm. The AR with 55-62gr ammo that most of us regular folks shoot is a 300-ish/400m rifle at best. A red dot with a magnifier will suffice. The ACOG -with a heavier and more expensive load- will push its limits to 550/600m.

    • SGT Fish

      FYI, some aimpoints are in fact made in china, especially commercial market ones

    So, does this mean that EOTech is officially dead?

  • Bill

    Does “competitive solicitation” include competitive testing?

    I’m kind of dubious.

  • alex waits

    Just great, now the FBI is going to have Sig decrease quality & power, just so their officers can handle it. : /

  • 22winmag

    Maybe the (F)ixing (B)ig (I)nvestigations can use these to better spot those missing emails.

  • Ex Light Infantryman

    Aimpoint T1/H1 are made in China.

    • Harry’s Holsters


      • Ex Light Infantryman

        Yes made in China, not the land of hot blonds. Aimpoint prefers to keep that on the downlow.

    • hking

      All aimpoint electro optics are made and serviced in Sweden. They are absolutely not made in China.

  • ??
  • VanDiemensLand

    I’d be uneasy about a primary optic with an auto off function, just me?

    • Dougscamo

      Must be…..

    • Bronson

      Me too.

    • Bill Jacobs

      On some Holosun products you can manually override the auto shut off. Not sure what they did for sig.

  • UVB76

    I want to compare the 4A to the 4M – very close in specs. I wonder if the IPX 7 vs 8 boils down to a particular O-Ring size… Any one have experience in how those two are usually separated on the electrical optical manufacturering process?

  • UVB76

    I doubt that. Maybe the 4M is reviewed by someone in the US and they add particular components/processes to add a little more robustness. Last I heard was the 4M had a few more coatings (?) and a higher submersion depth rating.

  • lifetimearearesident

    So far nobody has commented that they know these are produced in the USA which leads me to believe they are manufactured outside the USA. If there is a production line in the USA people will show up here and let us know where it is.

    Now to speculate. A USA based production line just for one order is simply way to expensive to justify the overhead. If the existing plant is in China or some other non-USA location the chances of setting up another production line in the USA is close to zero.

    • Frank

      I’d speculate that a US federal agency wouldn’t be buying them if they weren’t domestically made. They tend to favor that in most cases for gear. Either it’s setting a bad precedent or the 4M is being assembled in the US at least as part of the agreement to buy them. Considering the cost to make a red dot in the US I don’t see it as being unrealistic for them to set up manufacturing if they receive a larger enough order. It’s not as complicated as you’d imagine. Most of the machining work for a lot of the parts could be pretty easily handled and outsourced. The big up front cost is establishing assembly, but long term the costs of assembly, if automobiles are an indication, only account for about 18% of the total cost. All of this is speculation though.

      • GI

        Aimpoint and Elcan optics aren’t manufactured in the US, but are used extensively by federal agencies.

  • hking

    It says right on the ROMEO 4 box for all models “DESIGNED BY SIG SAUER IN OREGON ASSEMBLED IN CHINA”

  • GI

    Why would anyone buy one of these gimmicky Chinese things over a Trijicon MRO for the same price?

  • Bill Jacobs

    It’s all Holosun. China can make anything now. Tell them what you want they make it. Its that simple.

    • The Brigadier

      And 99 percent of it is made from inferior materials by mostly untrained workers. That is fine for a lot of things, but not to depend on in a firefight. Trump says he will bring back manufacturing to America and it can’t happen soon enough. China makes crap.

      • EC

        If Sig paid for inferior materials and untrained workers, then that’s what they got.

        But if Sig paid for high quality materials and highly trained workers, then China can certainly supply those as well.

        China makes crap only if our corporations want to sell crap. A lot of times our corporations get away with it. China clearly though can create high-quality goods… if the brand (and ultimately consumer) is willing to pay for it.

        For instance, think of the luxury-branded iPhones… very well made in China.

  • int19h

    Can someone clarify if it’s a traditional red dot (a la Aimpoint) – and if so, then how they made it into a reticle? – or holographic, like EOTech?

  • Tony

    Holosun supposedly makes Primary Arms
    If they only came with a lower 1/3rd co-witness.
    Is the screw pattern the same as Aimpoint Micros?
