Vertical forward grip
A vertical forward grip or foregrip is a vertical pistol grip mounted on the fore-end of a long-barrel firearm, designed for grasping by the frontal support hand (or "off hand"). == Use == Forward grips aid in the maneuverability of the firearm, since the natural angle of a person's outstretched hand is more oriented to grasping objects at a vertical angle, rather than a horizontal one perpendicular to the body.
