- "Fully shrouded monolithic integral suppressor keeps the weapon silent and increases range for longer distance stealth assaults."
- — In-game description
The CX-38S is a barrel attachment for the CX-9 submachine gun in Call of Duty: Modern Warfare and Call of Duty: Warzone. It increases the weapon's damage range, bullet velocity, and recoil control, all while keeping the gun sounds to a minimum, but at the cost of some mobility.
The attachment restricts the ability to put Muzzle attachments on the weapon due to its integrated suppressor.
