Lightweight vertical grips position your support hand close to the barrel to help you maintain maximum weapon control at all times. Ergonomically shaped design is optimized for use with the "thumb break" method of grasping the weapon, yet works just as well with a traditional vertical grip stance. Aggressive horizontal serrations on the front and back, plus crackle texturing on the sides ensure a secure grasp in all weather conditions. RVGÖ (Rail Vertical Grip) combines the MVG's ergonomic features with a conventional Picatinny attachment system for use on standard railed handguards. Includes an adapter that enables installation on many non-railed forends, too.
