KAK Sig MPX / MCX Buffer Tube Adapter


  • Enables the addition of an aftermarket arm brace or other pistol buffer tube accessory
  • Adapter is made of 6061 T6 aluminum, flat black anodized

If using a carbine style castle nut buffer tube there are two threaded alignment holes (10x32 thread) for tubes that use a notch for indexing. A 3/16 half dog socket set screw would be used for proper indexing.
