- "Extended suppressor adds considerable weight to the barrel, but greatly increases the muzzle velocity and reduces recoil to help with long range precision."
- — In-game description.
The Colossus Suppressor is an attachment exclusive to the Oden in Call of Duty: Modern Warfare. It increases sound suppression, damage range, and recoil control, while decreasing ADS speed and aim walking steadiness.
- There is a Model 680 shotgun that can be found with the Colossus Suppressor in Going Dark.
