Strike Industries Announces SI 2017 Pistol/Rifle, Based On MP5

Last night, Strike Industries unveiled their new SI 2017 Pistol/Rifle which is created by combining this aluminum upper receiver with an MP5 Trigger Group and barrel.  In case you’re wondering about the stock, it’s from a SIG MPX as they’ve incorporated the MIL STD 1913 rail to the rear of the receiver.  

It’s an interesting project as MP5 trigger packs do not have serial numbers and are not considered firearms.  Consequently, this means that the SI 2017 component will be the serial numbered item.  As you can see below, they’ve planned multiple upper lengths.

There aren’t a lot of details yet, but it will be on display in booth #20114 at SHOT Show 2017.

Update: We received this info from Strike Industries:

First and foremost we are keeping the system true to the standard MP5 being one of the most widely used platforms for LEO/MIL worldwide. We don’t want them to have to retrain to new operating procedures so still no bolt lock back. May be a possible upgrade in the future…

The upper is compatible with the already widely available MP5 Lower Receiver, Bolt and trigger pack, what we are aiming to provide is an updated modular upper with, barrel, handguard, and stock configurations for pistol, sbr and rifle options “user choice”.

It will feature continuous top rail, MLOK rail system, integrated flip up front and rear sights on all length options except the shortest length due to structural limits and feature an ambi charging handle.

  1. Definitely used this one in CoD: Near Future BS 27

    But no, if that’s M-LOK then combined with the monolithic up top you’ve obviously got infinitely better accessory/optic mounting than the standard MP5. Is there a specific advantage to the lower/trigger pack not being serialised? I only ask because usually it seems (believe the AR is a good example?) more advantageous to have a serialised lower and easy to obtain quick-swap uppers for lots of barrel length options.

      I believe it’s a technical issue: since the upper is what accepts the magazines and contains the chamber I believe that is the component that is actually considered by the ATF to be the “firearm”, therefore the serialization.

    That right there is pretty damn cool! My “want” list is steadily out pacing my “cash available” list!!

    Gonna be sought after in future set movies I would bet.

    Will these be made in China too?

    • Warren says:

      Probably since all their airsoft items are made there. I like how they don’t even hide that fact. Their tech drawings are exactly the same as their MadBull airsoft drawings. Google it!

    • Christian says:

      Taiwan is where they make the majority of their products, actually. The rest are US made. I spoke to the company at SHOT and they will be close to, if not over, fifty percent made in USA by year’s end. They have a strong relationship with Dupont there in Taiwan, so leaving that behind would be tough, I’m guessing. They did say their FFL and premium products will be or are now American made, which would include the MP5 and SI AR piston top ends. Hey, at least they’re honest about it. Let’s see what happens when President Trump lights a fire under importing corporations’ asses.

    Standard blowback or roller locked?

  5. Dan says:

    What’s magical use does that Allen looking device forward of mag well bring to the table?

    • Paul says:

      My guess is the allen wrench is holding the trunion inside the reciever, to keep the recoil spring from pushing it forward. If that is the case, the trunion, bbl., and BCG would all be MP5 spec., making it roller locked. Notice there is no bbl. installed.

  6. Matt says:

    Is that an Allen wrench take down pin? If so that is a new feature I haven’t seen before.

  7. James F. says:

    its an interesting concept. Why is the handguard so unusually large at the end, it looks like the barrel is small enough for it to be significantly smaller

    • Paul says:

      Notice that there is no bbl. installed. The “OG” MP5 was much smaller at the muzzle, especially with the narrow forearm, because it did not have to have a full length top rail, and did not have proprietary mounting points for forward accessories. Just eyeballing it, it doesnt look much larger than a Bravo or a Knights rail. Because the charging tube is larger than a gas tube or piston op rod, the top does look a bit fatter. Looks like just enough room to internally mount a suppressor.

      What I’m curious about is that pushpin in FRONT of the magazine well??? And, will it be available with or able to be retrofitted with a paddle mag release?

      • Paul says:

        I see it now. Paddle mag release right there in plain sight…. might be time for an eye exam.

    • Cuvie says:

      My guess is to fit a suppressor

  8. BravoMike says:

    It looks like an MP5 and an MPX had a drunken one night stand.

    • Fritzthedog says:

      The MPX gene pool is pretty shallow….. Poor kid.
      My Gen 2 MPX is heading back to Sig for the second time-crap gas system design.
