The Manticore Arms Tavor 7 Curved Buttpad features an aluminum skeleton structure with an overmolded rubber pad. The rubber pad is curved to conform to the shoulder and gives both better ergonomics and a better grip so the rifle does not slide around. Note: The Tavor Curved Buttpads and X95 Curved Buttpads ARE NOT interchangeable- each model of IWI Tavor uses its own dedicated buttpad. Please be sure to order the correct buttpad for your rifle.
