Have a Knights Armament M4QD suppressor? Yes? Then this suppressor insert kit is the one you need to be quieter than ever before!

The new GHOST design rivals even our Cloak Series inserts by providing even more decibel reduction!

**Note----installation is a key element for the Ghost Series! Follow the instructions provided!

No need to worry about diameters or lengths, this kit is already cut to go right into your Knights Armament M4QD suppressor!

Enhanced design:

  • Custom cut to fit inside diameters from 23.5 to 41.4mm 

  • 2 different types of ported inserts

  • Both types of inserts are ported specifically for air speed and decibel reduction while equally channeling air flow throughout the chamber so the path of the BB is not altered

  • Utilizes high quality open cell foam used specifically for sound/air absorption
  • Inhibits insert movement allowing the inserts to stay centered

  • Baffles(slows down) air and sound collisions throughout the length of the chamber

  • Does not utilize a tube or spring that can negatively affect air and sound flow


Made of Auralex type sound absorbing foam and laser cut to match your suppressor.

Comes with detailed instructions for installation and testing.

Many of the Ghost kits are made to order, so please allow up to 2-4 business days before shipment notification is sent to you. Thank you.

**If you have any considerable fitment issues, please contact us via email at Please provide brand and model of the suppressor, a picture of the issue, and a measurement of the INSIDE diameter of the suppressor. We will get a new kit out to you ASAP.  THANK YOU for your help!
