Strike Industries MP5 Upgrades | SHOT 2017

Strike Industries is in the works with a design to replace existing MP5 receivers, with a design that essentially revamps the existing H&K MP5 in Military and Law Enforcement armories all over the world. For right now it is in the prototype stages, but Strike is very keen on sharing their progress with the world, keeping the rest of us updated on the design process. What they have so far is an injection molded version that shows the industry the direction Strike is headed. Changing from existing MP5s to the Strike design would involve removing the bolt, and changing out the trunnion with barrel into the Strike receiver. All of this work can be done by a Police armorer, and won’t require the submachine guns being sent in to be revamped. The old trigger group is fitted into the receiver. Once completed, the receiver will be aluminum.

For right now the design is being aimed at the LE market, because of the prominence of MP5s. In comparison, the civilian legal MP5 market is somewhat smaller, and the amount of NFA MP5s out there is even smaller than that. But, I assume that if it becomes popular on the LE side, we might see a civilian introduction for NFA and civilian legal MP5s or HK94s.

Changes include an ambidextrous charging handle position with Strike’s charging handle. M-Lok rails are standard in the design on the forward rails.

BUIS’s are integral to the picatinny rail system.

Instead of an actual buttstock, the rear portion comes with a side mounted picatinny rail for the attachment of a picatinny mounted side folding stock. Or no stock at all as is evidenced by the cover photo.

    This has me intrigued. But I doubt it will be any more affordable than clone models of late. Which for my public servant salary is too much for a PCC. At least ETS is getting into MP5 mags now.

      !!! ETS will be making MP5 mags??
      Oh cool. Did a little digging, haven’t seen anything from them re: Shot Show though.

    It’s surprising that HK itself has not done these kinds of modifications to update the MP5, especially integrated rails.

    • AK™

      They possibly had a working prototype called the SMG II which was more modern than the MP5..

    “But, I assume that if it becomes popular on the LE side, we might see a civilian introduction for NFA and civilian legal MP5s or HK94s.”

    Isn’t the upper that is being replaced the serialized part with the MP5 and the rest of the HK Roller delayed family? I don’t see how that could ever work for NFA guns. You are buying a new firearm to put the parts from your old firearm on.

    • Removing the MP5’s trunnion from the receiver is not a trivial process either.

      • JumpIf NotZero

        …. Why are you talking about removing the trunnion!? The MP5 serial number is not anywhere near the trunnion.

        • Jonathan Ferguson

          Because the article states that you need to swap out the trunnion to install the upper.

        • The original article states: “Changing from existing MP5s to the Strike design would involve removing the bolt, and changing out the trunnion with barrel into the Strike receiver.”

          The MP5’s trunnion is retained by several spot welds in the stamped receiver. The easiest method to remove the trunnion is to drill the spot welds and then peel the sheet metal of the receiver away from the trunnion, breaking the remaining weld.

          • Ben Pottinger

            Exactly what I was thinking. This would be a stellar idea *if* they designed it to use a *new* barrel system that allowed a more modern AR “style” retention system. Swapping barrels in a HK roller locked gun is armorer level stuff (and not a trivial armorer level job either!).

            Basically a new gun with the lines of a MP5, the magazines, and the roller locked action but with a more modern assembly and modern optics/accessory mounting options.

    • Anon

      Not if it’s a registered sear…like many of them are.

  • Mr_X

    Call me quite skeptical, but the last foray with aluminum receivers and the HK series of weapons did not end so well on the longevity side.

    This also seems like a substantial amount of work to get features that are already widely available on the market (optical rails, forearm mounting solutions, folding stocks, etc.). Removing the trunion assembly from a built receiver isn’t something you do willy nilly with a Dremel and a hammer and punch. With the cost and collectable status of existing MP5/HK-94 series guns, I don’t see anyone being really keen to hack on their receivers for these debatable improvements.

  • Ron Walsh

    I would take one of these in a heartbeat. I have an MP5 I built from a kit, and another kit that would look great built up with one of these receivers.

  • machgman

    This is a SACRILEGE because its not German engineering!!!

  • g box

    Ok,problem 1) The upper is the serialized part. This is listed with ATF as the either SBR or Machine gun. New upper equates to a new gun maker and new gun.
    2) the Trunion on an Mp5 is welded into the steel upper receiver. So how is steel trunion going to be held into the new aluminum upper. Drilled and tapped then bolted? This will wear out, fatigue and crack. The rollers also run along the inside of the rails of the upper. Steel on aluminum, this will wear.
    I like the looks but don’t see this being feasible. They would be better if they produced a new gun with exemption for law enforcement.
