helps to control the gun, and prevent burns from the barrel during firing. A vertical foregrip can also allow for easier horizontal movement of the firearm, as it creates a firmer grasping point than conventional hand guards. Some firearms feature a vertical foregrip, This is used to steady firing and counter the effects of recoil, theoretically resulting in far more accurate fire when shooting in full auto mode. It can be incorporated in some rifles as part of the Rail Integration System, as in the image at right.

that can be fitted to most weapons. It decreases horizontal sway on attached firearm, but decreaes long range accuracy. It is one of the first attachments that is unlocked for all classes of weapons that it can be fitted to, but due to its extreme usefulness to light machine guns, it is unlocked in the later attachment and is classed as a primary attachment, and can be found in the underslung rails attachment category.
Aside from most of the Back to Karkand weapons, the player does not use the foregrip in a conventional manner, where the user wraps their fingers and thumb fully around it. Instead, the player uses a "thumb-brake" method, where the user's thumb rests on the handguard or R.I.S. of the weapon and the foregrip simply acts as a stop for the hand to pull against. This sometimes gives the appearance that the player is not actually using the foregrip at all.
