No rails are needed to add this shortened and lightened vertical grip. Made from indestructible glass filled nylon this vertical grip can handle the abuses of our hard use customers. The Direct-Mount Vertical Grip is KeyMod compatible with additional hardware that is sold separately. The Direct-Mount Vertical Grip is made by Unity Tactical in the USA.
