    Is it possible to put a folding stock adapter on this to make it more compact for transport?

  2. Troyd Wilson says:

    I just received my blade with the Sig MPX adapter. The adapter doesn’t fit onto the back of the MPX. Tried everything & it doesn’t fit. Is it possible I was sent the wrong adapter? Maybe I was sent the one for the scorpion. Please get back to me ASAP. Thanks

      Hello Troyd,

      Feel free to give me a call and we’ll see what the issue seems to be. The rear mounting rails on these SIG MPX guns don’t seem to be held to the best tolerances in our experience. Usually a good dosing of oil can get the adapter on a particularly large MPX rail.

      Thank you,

      Im having the same problem. It seems that the adapter is too small to fit the 1913 picatinny rail

        Make sure you are putting it on there absolutely square. And use a bit of oil as lube. It will go on there and be rock solid.

    Does this fold or is it fixed? Thanks

  4. Jonathan Russell says:

    Will the MPX still be classified as a pistol with the Shockwave blade kit, or will I need a stamp? I live in TX, if that helps. thanks!

      Yes, as long as you don’t use the Blade as a shoulder stock, according to ATF Tech Branch, the MPX remains classified as a pistol.
