KAK Industry has developed the SIG MPX adapter to assist you in adding the Shockwave Blade pistol stabilizer to your SIG MPX pistol.
The KAK SIG MPX adapter is made from a solid billet of 6061-T6 aluminum and then flat-black hard anodized.
Two threaded (#10-32) alignment holes in the bottom of the MPX adapter allow you to index your pistol buffer tube using the two included #10-32 x 3/1” half-dog socket set screws. Then just tighten your castle nut.
Note: This listing is for the adapter only.
