The Slim Vert Grip is a traditional, right angle vertical grip designed to be mounted to any M-LOK rail system. The contoured M-LOK base creates a smooth transition profile between the rail system and the vertical grip for superior ergonomics. The base of the Slim Vert Grip features a removable sliding baseplate for battery or supply storage. For your safety, Trinity Force recommends this part be installed by a competent, qualified gunsmith/installer with an understanding of the weapon platform that the part is being installed on. Always make sure the firearm is unloaded and pointed in a safe direction when working.
