Paratrooper (Barrel)

For the scorestreak in Call of Duty: WWII, see Paratroopers.

"Stainless-steel barrel increases muzzle velocity and range for more reliable damage at mid-range by improving the speed fired bullets travel."

— MP5 Gunsmith description

The Paratrooper barrel is an attachment type new to Call of Duty: Black Ops Cold War available for Assault Rifles, Submachine Guns, Shotguns and Pistols, increasing the effective damage range by increasing bullet velocity at the cost of diminished movement speeds while aiming and sprinting.
