China Lake

The China Lake is an American pump-action grenade launcher that appears in Call of Duty: Black Ops.

Call of Duty: Black Ops
Unlocked at level 48, it fills a similar role to the Thumper, however it holds four rounds and is more lethal than the Thumper in Modern Warfare 2. It uses the same 40mm grenade rounds as the Thumper, but is pump action instead of single shot. The pumping action is very slow, thus lowering the rate of fire as compared to a pump action shotgun, but is still significantly faster than the Thumper in Modern Warfare 2.

Although the pump is still faster than the Thumper's reload time without perks, it was included to prevent players quickly firing off shots, as unlike the Thumper, the Sleight of Hand perk cannot be used to reduce the time taken after each shot.

The China Lake is also used in some singleplayer campaign missions for missions that require you to clear out a heavy level of infantry/enemies.
