The Patent Pending Arisaka Vertical Grip is a robust, minimal grip for Picatinny handguards. It features a radiused profile at the top which tapers to meet the mounting surface on the handguard, giving a low-profile feel and ergonomic comfort. The grip is hollow, with no end-cap, and has no externally visible clamp hardware. Instead, it uses a unique recoil lug that extends from inside the part, providing a secure, rattle free lockup. The recoil lug and patched mating screw are captured and cannot fall out when the Vertical Grip is removed from the Picatinny rail.
