The grip attachment is available for light machine guns and shotguns. It is unlocked when a player achieves 75 kills with a light machine gun, and 50 kills with a shotgun. Using the grip attachment will replace a player's tier one perk. The foregrip is most useful for LMGs, as they have moderate-high recoil; the grip helps to maintain accuracy at range. 

The grip attachment is only available for the two shotguns, the Double-Barreled Shotgun and M1897 Trenchgun. It decreases weapon recoil just as in Call of Duty 4: Modern Warfare, and as previously, replaces the player's tier one perk. Instead of the polycarbonate synthetic pistol grip from Modern Warfare, foregrips are basically wooden handles, finished and fashioned into sticks that simply attach to the gun's gripping area. With this attachment, the Double-Barreled Shotgun has a small wood handguard under the barrels rather than a vertical grip.

The foregrip attachment is available for LMGs and Shotguns in Multiplayer. For LMGs, the Foregrip is the first unlocked attachment (Marksman I, 10 kills). For shotguns (except the Ranger and the Model 1887, they cannot accept foregrip), it is unlocked at Marksman III (75 kills). When attached to a shotgun it reduces the recoil but the bullet spread remains the same. When on an LMG it greatly reduces recoil allowing for much greater accuracy. Unlike Call of Duty 4: Modern Warfare and Call of Duty: World at War, the grip does not replace the Tier 1 perk.

The grip attachment returns in Black Ops. It can be mounted on the M60, the M14, theStakeout and every submachine gun except the MP5K. It costs 1000 to unlock. For some weapons attaching a grip instead attaches a stock such as seen on theSkorpion. On submachine guns with stocks on the unmodified weapon such as the Uzi, the stock will be folded when Grip is not used, but will be extended when Grip is used.
