Abstract: A hand-held, single-shot grenade launcher including a receiver and attached stocks for both hands, a barrel slidable in the receiver, an assembly of Belleville springs for absorbing recoil and a breech connected to the end of the barrel. A grenade round is manually inserted in a firing chamber defined by the breech and the inner end of the barrel and cammed into firing position by a sliding breech block that carries a pivotal firing lever operated by a striker mounted in the receiver. The striker is biased by a helical striker spring and is cocked by a cocking lever associated with the right hand grip. The weapon is fired by depressing the cocking lever and thus pulling the trigger to cam the striker upward and release it from a sear operated by the cocking lever. Upon release the striker impacts an arm of the firing lever to drive a firing pin carried by the other arm of the firing lever into the primer of the grenade round casing.
