Abstract: A firearm accessory is operable in two modes. A first mode in which the firearm accessory is coupled, at least indirectly, to a firearm to define a foregrip. In the first mode, a blade on the accessory is in a sheathed position. A second mode in which the firearm is disconnected from the firearm to define a knife. In the second mode, the blade is in an extended position. In each mode and position, the tip of the blade is vertically above the upper end of the grip body. The firearm accessory has prongs that connect the grip body to an attachment mechanism or coupler. Within the coupler are flexible liner locks that have sloped protrusions that engage recess in the blade to lock the blade in the extend position. The liner locks may be flexibly unlocked by depressing a button carried by the grip body.
