US Secret Service Issues Solicitation For a New Service Rifle

The United States Secret Service has put out a request for a new rifle, as listed on this Federal Government business solicitation page, and as reported by Soldier Systems Daily. I recommend reading both as they have different sets of information. There will be a conference in DC on April 4th for any companies/parties that are interested in participating in the competition. Essentially they want a 34 inch, folding stock, 5.56x45mm rifle for their agents. Soldier Systems Daily reported that this is probably going to be an upgrade from the Services current MP5sย (which they also have full length M4s, interestingly enough, most of their uniformed side uses them). They also want it to last 20,000 rounds, and 10 years in service, in addition to 10,000 such rifles. According to their website, they have 4,500 agents, so this contract will give them roughly twice the number of rifles that it would take to equip every single agent they have on staff. Of course, some of these agents probably won’t be issued this depending on their jobs, but it still seems like that is a large amount of rifles for the amount of agents they have, also factoring in guns going down for repair or replacement. They also mentioned that it could either be a direct gas impingement, or a piston operated gun, so it looks like they are looking for some sort of full auto AR15 platform as well. Interestingly there is nothing about magazine capacity, apart from the height which would limit it to maybe a 30 round STANAG magazine. The need for a 5.56x45mm round might be from the increasing threat of assailants with body armor that could stop the current 9x19mm MP5s that they are issued.

Dimensional Requirements:
Height (no taller than, w/o accessories) 8.5 inches

Weight (no heavier than, w/o accessories) 7.5 pounds

O/A Length (no longer than, w/stock fully extended) 34 inches

Barrel length (min โ€“ max)
10-12 inches

Rifling (5.56)
1 turn in 7 inch twist RH

The barrel shall have a minimum service life of 20,000 rounds.

Operating System
The weapon shall utilize a direct-impingement gas-operated system or a short-stroke gas piston system.

Mode of Fire.
The weapon shall be selective fire, i.e. semi-automatic and full automatic. A โ€œburst limiterโ€ in the full-automatic mode is not acceptable.

Fire Selector.
The fire control selector shall be ambidextrous in design, and be a single lever paddle mounted on the side of the receiver, adjacent to the rear pistol grip, thereby not requiring the shooter to significantly break their firing grip when actuating.

The fire control selector shall be a rotary type and shall have three positions; safe, semi-automatic and automatic and shall rotate manually without binding from one position to another.

  • Ray_G

    Hmmm, have they written a requirement for which Sig is the answer?

    • NDS

      Yeah sounds like somebody just rewrote the spec sheet for the MCX

      • JumpIf NotZero

        Miles is incorrect when he wrote that folding stock is a requirement. It’s not. Only bonus points to have a folding stock and an adjustable gas regulator.

        So, the MCX may fit this proposal. But… the SS is going to choose the best gun that fits the main requirements first. Does the MCX stand up against the KAC? Does folding stock even come close to making up that difference?

        I don’t know. The MCX might get selected, but against LMT’s new shorty, KAC, SCAR-L, 416A5 10″… There is some pretty serious competition.

        • TheSmellofNapalm

          My vote’s for KAC.

    • Petto

      Of course somebody in the Goverment really likes Sigs – MCX , MPX and Sig 320

    • mig1nc

      That or maybe the Remington ACR (LOL).

      • mig1nc

        Or I guess the SCAR. There are others, but I think the MCX or SCAR are probably the top.

        • younggun21

          The height and weight requirements might be an issue for SCARs. Perhaps its just cumbersome but stock SCARs have always seemed a bit on the heavy side even in the 5.56 configuration. MCX looks like the lightweight, short answer to the issue at an affordable price.

        • CommonSense23

          The SCAR that got dropped for performance reasons in SOCOM.

          • G0rdon_Fr33man

            The USSS does not play a lot in the sandbox though.

          • CommonSense23

            Ok, so why would you still pay more money for less performance. Especially a gun that has a reciprocating handle.

          • G0rdon_Fr33man

            I would not. This is however, your tax money. Are you surprised if your tax dollar are spent on silly things?

          • Israel asskissing conservative

            Didn’t get dropped.

            It simply wasn’t adopted because it didn’t really do anything that a Mk18 didn’t already do(better).

  • Anonymoose

    What happened to their SR-16s? Looking at the SR-16E3 CQB (11.5″ Commando version), it seems to be a perfect fit. Also, it doesn’t seem like the MCX has any barrels besides the 9″ and 16″ options, at the moment, but there is the 10″ SIG 516, and there is always the ever-popular HK416 and 10″ Mk16.

    • HKmaster

      Do you have any information about their use of the KAC SR16? I’m curious about what gov/mil contracts KAC has received for their 5.56 guns

      • Anonymoose

        That’s all I know of. The old wiki page for their LMG used to say that some PMCs used it, but that’s really iffy. Other than a couple pictures, we haven’t got much to go on for the USSS’s use of the SR-16, even.

        • JumpIf NotZero

          Definite PMC use. But that doesn’t mean much. I’ve talked to PMCs who had M16A2, 416, LMT whatever, KAC, SCARs, etc etc. Those guys get either Army hand-me-downs, or whatever the flavor of the month during purchasing was. I wouldn’t put too much stock into that metric.

          • iksnilol

            But badarse merc use has got to count for something?


      • alex

        USSS indeed have SR-16’s in their inventory. There was a picture of one when that guy jumped over the white house fence.

        Maybe they want the newer MOD 2. ๐Ÿ˜‰

    • mig1nc

      Actually if you look at the Sig LE catalog they list 11.5 like issued to the London met, as well as a 14.5.

    • younggun21

      I’m pretty sure that the Sig 516 still uses the standard buffer tube and as such would not meet the folding requirement. The 416 can use a shortened buffer tube but again I think that they want a true folder that is separate from a standard buffer tube and bolt carrier set up. Seems to me like the MCX is the answer to this request.

      • Anonymoose

        What folding requirement? Miles mentioned a folding stock, but it’s not on the requirements list.

        • younggun21

          From the article: “Essentially they want a 34 inch, folding stock, 5.56x45mm rifle for their agents.”

          • JumpIf NotZero

            Anonymoose is correct. Miles is incorrect.

            From the actual article I’m sure everyone read: Word is, offerers get bonus points for an adjustable gas block and folding stock.

            The request does not at all call for a folding stock. Only that it’s preferred.

          • younggun21

            Fair enough. If the standard buffer tube is acceptable though, why put out a request? It says right in the article that they are already using M4 rifles (presumably with the 14.5″ barrel) so why not just pick up an order for upper receivers that are shorter than that and save a bunch of money?

            I know everyone is gonna jump on this because the government is fine spending other peoples money and they are correct. However, it seems to me that if you are going to put out a request for a whole different weapon system than you have already ruled out the easy fix which would just be a shorter barrel on the rifles that you are already fielding such as the MK.18 set up or something of that sort.

          • JumpIf NotZero

            And they may well end up with Mk18s. It’s a preference. They clearly want to toss silencers on them (adj gas block) and keep them small. So in that case a folding stock may be nice for them to have. Those two things sort of go together imo. We’ll see what they select. MCX wouldn’t surprise me, but I’m predicting something closer to KAC or LMT or HK.

        • younggun21

          Also there is specific mention of having a OAL of 34″ “with stock fully extended.” It is possible I suppose that they simply mean a collapsible stock but the mention of the stock being fully extended reads to me like unfolded. Perhaps I am reading to much into it.

          Also would be a pretty short barrel for a 5.56 to get 34″ with a buffer tube and standard stock sticking out the back.

  • Major Tom

    This sounds like a job for an SG-553.

  • micmac80

    Talk about bloated goverment ,4500 agents to nanny around the politicans

    • TheMaskedMan

      There are a ton of Secret Service SAs that aren’t on protective detail. They investigate financial crimes as well.

      • Bill

        Indeed. Only a small percentage of agents are assigned permanently to protective details. And then there are agents assigned to protection details of former officials, but a lot of a field agent’s time is spent running down credit card scanners and interviewing nutballs who wrote weird letters to POTUS.

  • TheNotoriousIUD

    Doesnt this spec describe most SBR 5.56 rifles?

    • Israel asskissing conservative


  • Neyro

    Sounds like they need a Bren 805

    • JumpIf NotZero

      Not sure how you got there because not even the Czechs wanted the 805 which is now a model.

  • flyfishr

    This is nonsense, guns are bad.

    A simple “gun free Zone” is sufficient to keep the president safe.

    • JumpIf NotZero

      They do have a gun free zone. The only difference is it’s backed up with other guns and not signs. But all the same, their gun free zone works.

      • flyfishr

        Ummm no, first sarcasm. Second if gun free zones worked they wouldn’t need to be backed up by anything.

        • JumpIf NotZero

          I’m glad you pointed out sarcasm, as you missed it yourself.

      • john huscio

        Apparently not for JFK or McKinley……and Regan had a close call in his gun free zone….

        • ostiariusalpha

          Andrew Jackson let people shoot at him, but only on the condition that he’d get to murder them if they failed to finish him off.

          • Mark

            And Jackson killed the Bank that tried to kill him. Unfortunately for us all, the Bank was resurrected in 1913 and Jackson wasn’t there to take care of it.

  • Jake Franklin

    Sounds like 300blk might be a better fit but eh it’s above my pay grade.

    • JumpIf NotZero

      Why? What do they care about noise when suppressed? The 556 weights less. The 556 is lower recoil. It’s a NATO caliber they already have. Etc.

      • iksnilol

        Better range?

        I doubt you get a decent fragmentation range from a 10 inch barrel in 5.56.

        • CommonSense23

          Thats why you use a round designed for hunting and loaded for shorted barrels. Which already exist.

  • Guygasm

    Sounds like the Desert Tech MDR is a perfect fit.

    • JumpIf NotZero

      A gun that doesn’t actually exist yet is a perfect fit?

      • Guygasm

        Zing! The MDR is further along than many weapon systems solicited for military/gov contracts. It doesn’t have to be a civilian product first.

        • JumpIf NotZero

          No. It’s not.

          • Guygasm

            Calling the MDR “undeveloped” is a blatant lie. You can question reliability as it is not in the wild but your statement is just silly.

            As an example, the SCAR program had multiple rifle designs that were specifically developed for it by various manufacturers. How is this even in question?

    • Hensley Beuron Garlington

      I agree. The MDR-C, sounds like the prefect fit for what they want.

  • Roadkill

    They should just buy a shotgun. I’m sure Biden would be fine be protected with an SxS. It would get them some Fudd votes, too.

    • Jwedel1231

      If they would just shoot both barrels into the air, everyone would be too afraid to continue with an assassination.

  • kregano

    They might be better off getting a bullpup like the RDB for this, unless they switch to .300 Blackout SBRs or something.

    I would’ve said they should get the X95, but IIRC, that’s a long stroke gas piston, so it fails that requirement right out the gate.

    • GhostTrain81

      I was thinking the same thing… the AUG has a short stroke piston.

      But I just don’t see it happening… bullpups are un-American lolz ( )

  • Lance

    So in a way they’re not replacing there M-4sbut replacing the MP-5s currently in use. Sounds like its to supplement current weapons not fully replace everything,

  • Brian P.

    “Fully automatic SBRs for me but not for thee.”

    Remember folks, we’re just the filthy peasants. They can buy thousands of machine guns on a whim and have their bodyguards carry them everywhere, but they restrict, regulate, and otherwise eviscerate our ability to legally acquire arms and protect ourselves and our families.

    • Hensley Beuron Garlington

      That’s exactly right. We are not free and the Second is clearly infringed upon. ๐Ÿ™

  • USMC03Vet

    Weird I thought they had already replaced the MP5 with the FN P90. Maybe that was just for their uniform guys?

    • JumpIf NotZero

      Some, not all. Most recent fence jumper news had pics of MP5s.

      • Jwedel1231

        Then they should replace the rest with P90s ๐Ÿ™‚

  • NewMan

    HK 416

    • Travis

      No folding stock, and almost literally the same as the M4s they already have.

      • NewMan

        folding stock is not part of the requirement.

        • CommonSense23

          Doesn’t change the fact the M4 is still better than the HK.

          • iksnilol

            Norwegian Army seems to disagree ๐Ÿ˜‰

          • CommonSense23

            And SOCOM and multiple other organizations disagree.

    • CommonSense23

      Have you ever actually used a HK416

    • mosinman

      like others have said, why? they already have M4s

  • J E

    CZ 806 Bren 2 — 35.7in, 6lb. – stock extended, folding stock bonus point, adjustable regulator – bonus point…..

  • Scars sux

    Robinson XCR-L

  • Danny Wildman

    Maybe if politicians stopped mass murder and stealing trillions of dollars every year, they wouldn’t need all this taxpayer funded protection.

    Also ditto for the kind of person who spends their life protecting these scumbags.

    • Jwedel1231

      The agents are just doing their job, protecting elected officials. Hating someone for the actions of those they protect is wrong.

      • Danny Wildman

        “just doing their job” – the Fuhrerprinzip defense didn’t work for the Nazis so why should they work for these SS men?

        • CrankyFool

          For one thing because it didn’t work for committing war crimes, and Secret Service agents typically aren’t in the habit of committing war crimes.

          • Danny Wildman

            Alas, these American SS protect people who commit war crimes on a regular basis.

      • Very true. They don’t have to or agree with or like those they protect. They are still dedicated individuals who are willing to take a bullet for the protected person.


    An “off the shelf” bullpup or SBR should be good enough for the job. Long barrel rifles aren’t necessary for this kind of work.

  • iowaclass

    Here’s my counter-offer: You get an Ares SCR with a ten-round magazine.

    • JumpIf NotZero

      They are mostly in DC after all.

    • iksnilol

      Only loaded with 7 rounds if in NYC of course.

  • Jwedel1231

    This is dumb. Just buy a ton of P90s and be done with it. It’s better suited to this type of work anyway.

  • Hensley Beuron Garlington

    Desert Tech, are you reading? MDR-C, now! LOL.

  • MikeSmith13807

    Too bad Desert Tech doesn’t have the MDR ready… their MDR-C setup is the perfect solution for this application (10″ barrel, 21″ overall length, no folding or unfolding stock). Or if they want a full-length barrel it’s still only 26″–you could add a suppressor and still be shorter than an unsuppressed AR.

  • TheSmellofNapalm

    Sounds like this is right up KAC’s alley with their CQB MOD 2.

  • Joshua

    Do you know if in the request somewhere they classify the firearms as “assault weapons,” or “personal defense weapons” or anything else like that? Everytime a government agency makes this kind of request, this detail should be noted and disseminated to the “pro-gun” folks.

  • Icer

    They’re going to get the MCX.

  • Geoff

    I don’t get it. I thought guns make people less safe.
    Why would an agency in charge of keeping certain people safe want guns?
    Does not compute….

    • Doug


  • Kivaari

    Going with an AR makes sense.

  • Blake

    I thought they had a large number of FN P90s?

  • Captain obvious

    Ruger ac556… Good enough for the A Team and the French, good enough for the USSS

  • Jonathan Wright

    I vote Ares SCR with a short upper…and wood furniture, because black guns are terrorist baby killing machines of death.

  • Nimrod

    USSS be gearing up in case Trump gets in. They gonna need lots more agents to protect him.

  • zippiest

    Why don’t they lead by example, and get rid of all of their guns? When those that protect the president disarm, those who protect themselves will disarm. Until that day comes, I’ll just go ahead and continue to adequately armed myself for the defense of myself and loved ones.

  • Austin

    Sounds like a showdown with the normal players. I’m guessing MCX, 416 and SCAR-P as the contenders

  • HSR47

    If I had to guess, they’re looking to get that many rifles so that they can be sure that they have enough when and where they need them.

    If they have enough firearms, they can send them with the advance team so that they’re on location when the protectee arrives. International travel likely complicates this further.

  • Miguel Raton

    Dust off your resumes people, sounds like the Secret Service is going to be hiring! Seems like they foresee a lot more attempts on whomever is next in office [if Hillary: all the people who don’t want a treasonous criminal in office; if Trump: all the Kool-Aid drinkers who’ve been convinced by the non-stop media attacks that he’s somehow a reincarnation of Hitler…]

    • Bill

      Well, having people swear fealty to him at his rallies is sorta reminiscent of 1930’s Germany…I wouldn’t be a bit surprised if he proposed that all Muslims wear a yellow “M” on their clothing.

      I’d hate to be on his protection detail, but I bet that’s where the action will be as this drags on.
